Borrowed Boyfriend

The house on the quiet cul-de-sac in Ilsan always smelled like miso soup and fresh laundry on weekday mornings. Not the sharp, artificial kind from those fancy downtown apartments. Real laundry, sun-dried on the balcony where the wind carried faint traces of cherry blossoms from the park across the street. It was the kind of smell that wrapped around you like an old blanket, promising that nothing ever changed here. The same blue gate. The same wind chimes that tinkled whenever someone stepped outside. The same routine that had run like clockwork since the two Shin daughters were small enough to fight over the last strawberry on the breakfast table.

Upstairs, in the smaller bedroom at the end of the hallway, Yuna stirred before her alarm even had the chance to beep. She always did, but still the first one to awake, as if her body had memorized the rhythm of the house better than any clock could. She slipped out of the bed without making any sound, bare feet meeting the warm wooden floor she’d helped her father sand and varnish two summers ago. The oversized sleep shirt which she borrowed of course, brushed the tops of her thighs as she padded to the window and cracked it open just enough for the cool spring air to slip inside.

She stood there for a long moment, letting the breeze lift the strands of her hair that had escaped her loose braids overnight. From this angle, she could see the neighbour’s cat stretching on the roof of their garage, the delivery truck idling at the end of the street, the faint pink haze of dawn still clinging to the edges of everything. Ordinary. Peaceful. Exactly the way she liked the world to look from the outside.

Downstairs, her mother was already humming an old trot song while slicing green onions. Her father would be in the living room soon, folding the newspaper with that same satisfied sigh he gave every morning, as if the headlines had personally agreed to behave themselves. And somewhere in the bigger bedroom across the hall, her older sister was probably still buried under three layers of blankets, dreaming about whatever important things lawyers-in-training dream about.

The younger girl smiled at the thought. Small, private, the kind no one ever saw. Yuna moved through her morning like a shadow that belonged there, folding her blankets into perfect hospital corners, smoothing the sheets until not a single wrinkle remained, arranging the two plushies on her pillow exactly as they had been the night before. Then came the small rituals no one noticed. The way she opened her sister's closet door which was never locked and never questioned, and let her fingers trail lightly over the row of hoodies. The cream one with the tiny embroidered rabbit on the sleeve. The oversized black one that still carried the faintest trace of her sister’s favorite perfume. Yuna chose the cream today, slipping it on over her sleep shirt, rolling the sleeves just once so the cuffs kissed her wrists. It was warm. Familiar. Hers for the next few hours, at least.

No one ever minded. That was the beauty of it. She always returned everything. Washed, pressed, smelling like the same fabric softener her mother used. A little note sometimes, written in her neat, rounded handwriting.

“Thank you, unnie 💕 borrowed for a bit!”

Her sister would laugh and call her a little magpie, ruffle her hair, and never once suspect that every borrowed item had been studied, worn, breathed in, and memorized. That each one had been a quiet test of how easily something could become hers if she wanted it badly enough.

Yuna caught her own reflection in a full-length mirror on the closet door and tilted her head, practicing the smile she gave the world every single day. Soft eyes, slightly parted lips, the tiniest dimple that appeared only when she was being “adorable”. It was flawless. It had taken years to perfect it. Behind it, something else stirred, something patient and warm and endlessly curious, but she tucked it away like she always did, folding it neatly between the layers of her ordinary morning.

By the time she reached the kitchen, the smile was already in place. “Good morning, eomma,” Yuna said, voice still a little husky from sleep, and accepted the kiss on her forehead like it was the most natural thing in the world. She set the table with quiet efficiency, poured barley tea into four cups, arranged the side dishes exactly the way her father liked them. When her sister finally stumbled downstairs, hair messy and eyes half-closed, the younger girl greeted her with the same bright, harmless sparkle she gave everyone.

“Unnie, you look so pretty even when you just woke up,” she said, sliding a plate of perfectly cut fruit across the table.

Her sister laughed, called her a flatterer, and stole the biggest strawberry—the same way she had since they were kids.

And the younger girl just smiled wider, because some things were worth waiting for.

Some things you didn’t borrow all at once. You waited until the perfect moment, until the wanting had grown so quiet and so certain that no one—not even the person you were about to take it from—would see it coming.She had always been very, very good at waiting.

Breakfast blurred into the familiar hum of family chatter. Her father commented on the stock market between bites of kimchi, her mother fussing over whether the rice was too sticky today, her sister scrolling through her phone with one hand while absentmindedly stirring the tea. Shin Yuna, though no one ever called her by her full name unless she was in trouble, sat quietly at her usual spot by the window, legs tucked neatly under the table, listening more than speaking. She nodded at the right moments, passed the soy sauce without being asked, and let the conversation flow around her like water around a stone.

It was easy. Effortless, really. She had spent years perfecting this—being present without drawing too much attention, a soft glow in the background of everyone else's brighter lights. Her sister, Miss Shin, was the one who commanded the room without trying: twenty-three, sharp-minded, on track to pass the bar exam with flying colors. The kind of daughter who made parents beam at neighborhood gatherings. "Our eldest is going places," they'd say, and Yuna would stand beside them, smiling that same dimpled smile, adding a quiet "Unnie's the best" that always made the praise feel even warmer.

Not that Yuna minded. She liked the shadows. They gave her space to watch, to notice things others missed. Like how her sister's fingers tapped impatiently when their mother started talking about blind dates set up by well-meaning aunts. Or how her father always saved the crispiest piece of jeon for Yuna, slipping it onto her plate with a wink when no one was looking. Small details, tucked away like treasures in the back of her mind.

After breakfast, she cleared the table with her usual efficiency, stacking plates in the sink and wiping down the counters until they gleamed. Her mother patted her cheek in passing. "What would we do without our Yuna?" she said, and Yuna ducked her head, murmuring something about it being no big deal. Upstairs, she changed into her university clothes: a simple white blouse tucked into high-waisted jeans, the borrowed hoodie zipped halfway up. She brushed her hair until it fell in soft waves, applied just a touch of tinted balm to her lips—nothing flashy, nothing that screamed for attention. That wasn't her style.

The walk to the subway was the same as always: past the corner convenience store where the owner waved hello, down the tree-lined path where joggers nodded politely, onto the platform where she stood at the edge, backpack slung over one shoulder, earbuds in but no music playing. She preferred the ambient sounds—the rattle of incoming trains, snippets of conversations from salarymen and students alike. It made her feel connected without having to participate.

Classes dragged on the way they always did: literature in the morning, where the professor droned on about symbolism in Han Kang's novels; sociology after lunch; group discussions that Yuna contributed to just enough to avoid standing out. She took notes meticulously, her handwriting a series of elegant loops and dots, but her mind wandered in the quiet spaces between lectures. To the hoodie she was wearing, how it still smelled faintly of her sister's vanilla lotion. To the earrings she'd "lost" for her last month, now safely hidden in her drawer. By the way, borrowing felt like a secret game, one where she always won because no one else knew they were playing.

By afternoon, the campus cafe was her refuge. She ordered an iced Americano—no sugar, extra ice—and found a corner table by the window, pulling out her phone to scroll through social media. Her feed was a curated collection of softness: cafe aesthetics, study tips, photos of her and her sister at family outings. She liked posts from classmates, commented heart emojis on her friends' selfies, and paused on a picture her sister had uploaded the night before—a candid shot of her at a study group, laughing with books piled high. Yuna saved it to her gallery, zooming in on the details: the necklace glinting at her collarbone, the way her hair caught the light.

She wondered, idly, what it would be like to step into that frame. To wear that necklace, sit in that chair, laugh that laugh. Not out of envy—not exactly. More like curiosity. A quiet hunger to know how things felt from the other side.

The train ride home was crowded, bodies pressed close in the evening rush. Yuna stood near the door, one hand gripping the overhead strap, her free fingers drumming lightly against her thigh. She caught a stranger's eye across the car—a college guy, maybe, with messy hair and a backpack covered in pins. He smiled, tentative. She smiled back, soft and fleeting, then looked away. That was enough. She wasn't interested in strangers. Not today.

Back home, the house welcomed her with the scent of simmering jjigae. Her mother was in the kitchen, an apron tied around her waist, and her father was dozing in his armchair with the TV murmuring news in the background. Yuna kicked off her shoes, hung her backpack by the door, and called out a soft "I'm home." Hugs from her mother, a sleepy nod from her father. Routine. Comforting.

It was only when she reached the top of the stairs that things felt... different. Her sister's door was cracked open, light spilling into the hallway. Voices inside: her sister's laugh, light and teasing, followed by a deeper one—male, unfamiliar but warm. Yuna paused, hand on the banister, listening.

"Unnie?" she called softly, pushing the door open just enough to peek in.

Her sister looked up from her bed, phone in hand, face lit by the screen. "Yuna-ya! Come in, come in. I was just telling Mom and Dad—I have someone I want you all to meet this weekend."

Yuna stepped inside, perching on the edge of the bed, her expression the perfect mix of curiosity and innocence. "Really? Who?"

"A guy from my study group. We've been seeing each other for a bit. He's... nice. You'll like him."

Yuna tilted her head, smiling that dimpled smile. "If unnie likes him, I know I will."

Inside, though, that quiet something stirred again—warmer now, more insistent. She didn't say anything else. Just nodded, asked a few polite questions, and excused herself to her room.

She closed her door softly, leaned against it for a moment, and let out a slow breath. The hoodie suddenly felt heavier on her shoulders. Borrowed. Familiar.

But this? This was new.

And Yuna, ever the patient one, felt the first real spark of anticipation flicker to life.She had time. The weekend was still days away. Plenty of time to wait. To watch. To wonder.

The days leading up to the weekend blurred into a comfortable haze for Yuna, each one layering on the last like pages in a well-worn notebook. She went through her routines with the same quiet precision: mornings in the kitchen, helping her mother chop vegetables for lunch boxes; afternoons buried in library stacks, her laptop screen glowing with half-finished essays; evenings curled up on the living room couch, half-watching dramas with her family while her mind drifted elsewhere.

But underneath it all, that new spark lingered—a subtle warmth she carried like a hidden phone on vibrate, buzzing faintly at the edges of her thoughts. She didn't poke at it. Didn't analyze it. She just let it sit there, growing accustomed to its presence. Her sister mentioned the boyfriend a few more times in passing: his name was Jihoon, he worked in marketing, he had a laugh that made her cheeks flush when she talked about him. Yuna listened with wide-eyed interest, asking questions that sounded innocent enough—"What's he like, unnie? Does he like the same movies as you?"—and filed away the answers like she did everything else.

Thursday evening, after dinner, Yuna found herself in her sister's room again. Miss Shin was packing for a quick study trip the next day, tossing clothes into a duffel bag while humming off-key to some pop song on her playlist. Yuna perched on the bed, legs crossed, idly folding a stray shirt that had missed the bag.

"Unnie, what should I wear for dinner on Saturday?" Yuna asked, her voice light, as if the question had just popped into her head. "I want to look nice since it's special."

Her sister paused, glancing over with a fond smile. "You always look nice, Yuna-ya. Just wear whatever—maybe that cute sweater Mom got you for your birthday? The pink one with the buttons."

Yuna nodded, but her eyes had already wandered to the open closet. There, hanging toward the back, was a dress her sister rarely wore: soft blue fabric, fitted at the waist, with a hem that skimmed just above the knees. Simple. Elegant. The kind of thing that said "grown-up" without trying too hard.

"Can I borrow something of yours instead?" Yuna asked, tilting her head with that practiced shy smile. "Just for the night? It'd make me feel... I don't know, more confident."

Miss Shin laughed, waving a hand. "Sure, take whatever. You know the rules—bring it back clean."

Yuna reached for the blue dress, holding it up against herself in the mirror. It fit like it had been waiting for her: hugging her curves in a way that felt natural, effortless. She twirled once, the fabric whispering against her skin, and caught her sister's eye in the reflection.

"See? Perfect," her sister said, zipping up the bag. "Jihoon will think you're adorable."

Yuna's smile deepened, just a fraction. "Thanks, unnie."

That night, alone in her room, she tried on the dress again. No audience this time—just her and the mirror, the soft glow of her bedside lamp casting long shadows across the floor. She smoothed the fabric over her hips, turned to see how it fell from behind, and let her hands linger a moment longer than necessary. The material was cool, silky, a contrast to the warmth building in her chest.

She imagined eyes on her—not her family's, not her friends'. Strangers, maybe. Or someone specific. Someone who might see past the buttons and the hem to the girl underneath, the one who borrowed not just clothes, but moments, feelings, desires.

But she shook the thought away, hanging the dress carefully in her own closet. Patience. That was her strength. The weekend was almost here, and with it, the chance to see how far a borrowed dress—and a borrowed glance—could take her.

Friday passed in a drizzle of rain that tapped against the windows like impatient fingers. Yuna spent it indoors, baking cookies with her mother (chocolate chip, her father's favorite), studying for a quiz she already knew she'd ace, and scrolling through her phone in bed long after lights out. She searched Jihoon's name idly, piecing together fragments from social media: a profile picture of him at a cafe, arms crossed, smile easy and confident; posts about weekend hikes, work rants, the occasional photo with friends. Nothing groundbreaking. But enough to paint a picture—a canvas she could fill in with her own colors.

By Saturday morning, the rain had cleared, leaving the air crisp and full of promise. Yuna woke early, as always, and went about her day with a quiet hum of energy. She helped tidy the house, arranged fresh flowers on the dining table, and chose her outfit for the evening with care. Not the blue dress—not yet. That was for later. For now, jeans and a simple tee, the borrowed hoodie thrown over top like armor.

As the afternoon sun slanted through the windows, her sister texted from the train: On my way back with Jihoon. Be home soon!

Yuna read the message twice, then set her phone down. She stood in the kitchen, pouring herself a glass of water, and took a slow sip.

The spark inside her wasn't buzzing anymore. It was steady now. Ready.

She had waited long enough.

The doorbell chimed at exactly 6:47 PM, a soft, melodic ping that echoed through the house like the start of a familiar song. Yuna was in the living room, fluffing the cushions on the couch for the third time that afternoon, when she heard it. Her mother bustled out from the kitchen, wiping her hands on a dish towel, while her father muted the TV and straightened his shirt. The air carried the rich aroma of bulgogi sizzling on the stove, mixed with the subtle sweetness of freshly steamed rice—her mother's go-to menu for important guests.

Yuna smoothed her hands over her jeans, took a steadying breath, and followed her parents to the door. She positioned herself just behind them, peeking over her father's shoulder with that wide-eyed curiosity she had mastered years ago. The door swung open, and there they were: her sister, Miss Shin, cheeks flushed from the cool evening air, arm linked with a tall figure beside her.

"Everyone, this is Jihoon," her sister announced, voice bright and a little breathless, as if she'd been practicing the introduction on the train ride over. She stepped inside first, kicking off her shoes and hugging their parents in quick succession. Jihoon followed, bowing politely—deep enough to show respect, but not so formal it felt stiff. He was exactly as Yuna had pictured from the scattered social media glimpses: mid-twenties, with neatly styled hair that fell just over his forehead, a casual button-down shirt tucked into chinos, and a smile that crinkled the corners of his eyes. Handsome in an approachable way, like the guy next door who'd help carry groceries without being asked.

"Nice to meet you all," Jihoon said, his voice steady and warm. He extended a hand to her father first, then her mother, who beamed and waved him off with a laugh, pulling him into a quick hug instead. "I've heard so much about your family. Thank you for having me."

Yuna waited her turn, hands clasped loosely in front of her, head tilted just slightly to one side. When Jihoon's gaze finally landed on her, she felt that inner spark flare—not dramatically, not enough to show, but enough to make her pulse tick up a notch. "And you must be Yuna," he said, extending his hand with an easy grin. "Your sister talks about you all the time. Says you're the smart one in the family."

Yuna took his hand, her grip light but lingering for the briefest second longer than necessary. His palm was warm, calloused just a little at the base of his fingers—maybe from gym workouts or typing at a desk all day. She met his eyes with her softest smile, the one that made her dimples appear like hidden treasures. "Hi, oppa," she said quietly, the honorific slipping out naturally, innocently. "Unnie exaggerates. But it's nice to meet you too. Come in—dinner's almost ready."

She stepped aside, gesturing toward the living room, and watched as he toed off his sneakers, placing them neatly by the door. Her sister chattered away, filling the air with stories about their train ride and the funny old lady who'd shared her snacks with them. Yuna listened, nodding along, but her attention drifted to the small details: the way Jihoon's shoulders moved under his shirt as he hung up his jacket, the faint scent of his cologne—something clean and woody—that wafted past as he brushed by her. Nothing overt. Nothing anyone would notice. But to Yuna, it was like adding another piece to her private collection.

They migrated to the dining table, her mother insisting everyone sit while she brought out the dishes. Jihoon took the seat across from Yuna's sister, leaving Yuna at the end of the table, diagonal from him—a perfect vantage point. As the conversation flowed—her father asking about Jihoon's job, her sister jumping in with anecdotes—Yuna played her part flawlessly. She passed the banchan bowls with both hands, refilled water glasses before anyone had to ask, and laughed softly at the right moments. "Oppa, try the bulgogi," she said at one point, sliding the plate closer to him. "Eomma makes the best marinade."

Jihoon glanced up, fork midway to his mouth, and nodded with genuine appreciation. "This is amazing, Mrs. Shin. Thank you." His eyes met Yuna's again, brief but warm. "You're right, Yuna—best I've had."

She ducked her head, murmuring a quiet "I'm glad," and let the compliment settle inside her like a borrowed trinket tucked into her pocket. The meal stretched on, comfortable and unhurried, filled with the clink of chopsticks and easy laughter. Her sister dominated the stories, as she always did, but Yuna didn't mind. She was content to observe: the way Jihoon's hand rested casually on the table near her sister's, fingers occasionally brushing hers; the subtle glances he gave when she spoke, full of quiet affection.

By dessert—fresh fruit and a plate of the cookies Yuna had baked the day before—the spark inside her had settled into a steady glow. Not urgent. Not yet. But present, warming her from the inside out as she watched, waited, and wondered how long it would take for a glance to turn into something more.

As the evening wound down, her parents excusing themselves to clear the table, Yuna stood to help, stacking plates with her usual quiet grace. Jihoon offered to pitch in, but she waved him off with a smile. "Guests don't do dishes, oppa. Sit—talk to unnie."

He chuckled, settling back into his chair. "Alright, if you insist."

She carried the stack to the kitchen, the sound of her sister's laughter following her. In the sink, under the running water, Yuna let her mind wander just a little further. Borrowing a hoodie was easy. A dress, even easier.

But this? This would be something worth the wait.

And Yuna, as always, was very good at waiting.

The evening lingered like a half-finished sentence, the kind that hangs in the air and makes you wonder what's coming next. After dinner, the family migrated to the living room, her parents settling into their usual spots on the couch while her sister and Jihoon claimed the armchairs across from them. Yuna hovered for a moment, debating where to sit, before choosing the floor cushion near the coffee table—close enough to be part of the circle, but low enough that she could observe without being the center. She tucked her legs under her, smoothing the borrowed hoodie over her knees, and reached for the remote to queue up a light variety show her mother liked.

Conversation ebbed and flowed, easy topics at first: Jihoon's favorite hiking spots around Seoul, her father's stories from his own college days, her sister's animated recap of a recent case study that had kept her up late. Yuna contributed sparingly—a soft laugh here, a nodded agreement there—but her eyes moved freely, tracing the room's dynamics. She noticed how Jihoon leaned forward when her sister spoke, his attention undivided, genuine. How his fingers tapped lightly on his knee during pauses, a subtle rhythm that matched the upbeat music from the TV. How, every so often, his gaze would drift—just for a second—to include her in the circle, as if making sure she wasn't left out.

"Oppa, do you like spicy food?" Yuna asked during a lull, her voice cutting through the chatter like a gentle breeze. She looked up at him from her spot on the floor, chin resting on her hand, expression open and curious. "Unnie hates anything too hot, but Eomma's kimchi jjigae is legendary. We could make some next time you come over."

Jihoon turned to her, surprised but pleased by the direct address. "I love spicy—I grew up on it. That sounds great, Yuna. I'd be down to try it." Her sister chuckled, nudging him playfully. "Careful, she's recruiting you for kitchen duty already."

Yuna smiled innocently, shrugging one shoulder. "I just like cooking with people. It's fun."

The exchange was brief, harmless, but it planted a seed. As the night wore on, her parents began to yawn, excusing themselves around 10 PM with warm goodnights and a final round of thanks to Jihoon for coming. "Drive safe," her father said, clapping him on the shoulder. Her mother added a hug and a whispered "He's a keeper" to her sister that Yuna pretended not to hear.

Left alone in the living room, the three of them chatted a bit longer—lighter now, with her sister teasing Jihoon about his terrible taste in movies and Yuna chiming in with a quiet endorsement of a rom-com they'd all seen. But eventually, the clock ticked toward 11, and Jihoon stood, stretching his arms overhead. "I should head out. Early meeting tomorrow."

Her sister walked him to the door, Yuna trailing a few steps behind like a polite shadow. At the threshold, Jihoon turned, bowing slightly again. "Thanks for everything. It was really nice meeting you all—Yuna included."

Yuna met his eyes, her smile soft under the porch light. "Come back soon, oppa. We can do that jjigae."

He laughed. "Deal."

The door closed behind him, and her sister let out a contented sigh, leaning against the frame. "What do you think, Yuna-ya? He's pretty great, right?" Yuna nodded, looping her arm through her sister's as they headed back inside. "Yeah, unnie. Really great."

Upstairs in her room, Yuna changed into her sleep shirt, the blue dress still hanging in her closet like a promise unspoken. She brushed her teeth, washed her face, and climbed into bed, the events of the evening replaying in her mind like a favorite highlight reel. Jihoon's smile. His laugh. The way "oppa" had rolled off her tongue so easily, and how it had made his eyes linger just a beat longer.

She wasn't rushing. That wasn't her way. But as she stared at the ceiling, the glow inside her felt a little brighter, a little more defined.

The first visit was just that—the first. There would be more.And Yuna, patient as ever, closed her eyes with a small, secret smile.

The weeks that followed slipped by in a rhythm that felt almost too predictable, but Yuna found comfort in the sameness—it gave her time to plan without anyone noticing the subtle shifts in her routine. Jihoon became a semi-regular fixture in the Shin household, dropping by every other weekend or so, usually for casual dinners or movie nights that her sister orchestrated with increasing enthusiasm. Each visit was marked on the family calendar in Miss Shin's bold handwriting: "Jihoon over—bulgogi?" or "Movie night w/ oppa." Yuna glanced at it every morning over breakfast, her finger tracing the dates like a map to hidden destinations.

She didn't change everything at once. That would have been too obvious, too unlike the Yuna everyone knew. Instead, she started small, testing the waters with the precision of someone dipping a toe into a pool before diving in. On the second visit—a lazy Sunday afternoon where Jihoon came over to help her sister with some work project—Yuna opted for simplicity. She wore her usual oversized tee, but paired it with shorts that rode just a little higher than normal, the kind that showed the smooth curve of her thighs when she crossed her legs. Nothing scandalous. Just enough to draw a fleeting glance if someone was paying attention.

They were all in the living room that day, papers spread out on the coffee table, her sister explaining some legal jargon while Jihoon nodded along, laptop balanced on his knees. Yuna had excused herself to the kitchen earlier, returning with a tray of iced teas and sliced fruit. She set it down carefully, bending at the waist rather than kneeling, feeling the hem of her shirt lift ever so slightly. She didn't look back to check if he'd noticed—just straightened up with her usual smile and settled into the armchair across from him, legs tucked up casually.

"Oppa, do you need more ice?" she asked, her voice soft amid the rustle of papers. She leaned forward to push a glass toward him, the motion pulling her shirt taut across her chest for a brief moment.

Jihoon looked up, his eyes meeting hers before flicking down to the glass. "Oh, thanks, Yuna. This is perfect."

Her sister glanced over, oblivious, and ruffled Yuna's hair. "You're the best hostess, Yuna-ya. What would we do without you?"

Yuna laughed lightly, waving it off. "It's nothing, unnie." But as she leaned back, crossing her legs slowly, she caught it—a quick shift in Jihoon's posture, his gaze lingering on her bare skin for just a heartbeat before he refocused on the screen. It was subtle. Blink-and-miss-it. But to Yuna, it was like finding a new trinket in her collection: small, shiny, full of potential.

The afternoon dragged into evening, the work session giving way to takeout pizza and a mindless action flick on TV. Yuna stayed put, commenting occasionally on the plot twists, but mostly watching the way Jihoon interacted with her family. He was good at it—charming without trying too hard, making her parents laugh with stories from his office mishaps. Every so often, though, when the room's attention was elsewhere, Yuna would stretch her arms overhead, arching her back just enough to make her shirt ride up an inch or two, exposing a sliver of midriff. Or she'd reach for a slice of pizza, her fingers brushing close to his as she handed him a napkin.

By the time Jihoon left that night, waving goodbye from the doorway with her sister tucked against his side, Yuna felt the glow inside her deepen. It wasn't about the shorts or the stretches—not really. It was about the awareness she was building, layer by layer, like stacking borrowed books on a shelf until the weight became impossible to ignore.

The third visit came mid-week, a surprise drop-in after Jihoon's work meeting ran late nearby. Her parents were out at a neighborhood gathering, leaving just the three of them to fend for dinner. Yuna had been in the shower when the doorbell rang—perfect timing, or so it seemed. She heard her sister's voice downstairs, the low murmur of greeting, and took her time drying off. Wrapped in a fluffy white towel that barely skimmed her thighs, hair damp and cascading over her shoulders, she descended the stairs with light steps.

"Unnie? Is that oppa?" she called out innocently, pausing at the bottom step where the living room came into view.

Her sister turned from the kitchen counter, where she was unpacking delivery bags. "Yuna-ya! Yeah, Jihoon just got here. We're doing jjajangmyeon—want some?"

Yuna nodded, stepping fully into the room, the towel knotted loosely at her chest. Water droplets still clung to her collarbone, tracing slow paths down her skin. "Sounds good. Hi, oppa," she added, turning to Jihoon with a shy smile. He was seated at the table, phone in hand, but his eyes lifted—and held. Just for a second, his expression flickered, surprise mixed with something warmer, before he cleared his throat and looked away.

"Hey, Yuna. Didn't mean to interrupt your evening," he said, voice steady but a touch quicker than usual. "No interruption," she replied, padding closer to grab a glass from the cabinet. She reached up on her tiptoes, the motion causing the towel to shift ever so slightly, hugging her curves a little tighter. "I was just finishing up. Let me change quickly—be right back."

She didn't linger. Didn't push. Just flashed another dimpled smile over her shoulder and headed upstairs, feeling the weight of his gaze follow her for a breath or two. In her room, she slipped into comfy lounge pants and a cropped tank—nothing too revealing, but short enough to show a hint of toned stomach when she moved. By the time she rejoined them, the moment had passed, dissolved into casual chatter over noodles and shared chopsticks.

But Yuna knew better. Moments like that didn't dissolve. They lingered, like the scent of shampoo in damp hair, waiting for the next breeze to carry them further. And as the visits continued, so did her quiet game—each one a step closer to the borrowing she truly craved.

Yuna's game evolved with each passing visit, subtle as a whisper but persistent as the tide. She never overplayed her hand— that would shatter the illusion she'd so carefully built. Instead, she wove her temptations into the fabric of everyday moments, making them feel accidental, inevitable. A brush of her arm against his as she passed him a controller during a family game night. A lingering hug goodbye that pressed her just a fraction closer than sisterly affection demanded. Small things, stacked like borrowed books, until the pile teetered on the edge of collapse.

The fourth visit was a rainy Saturday, the kind where the sky hung low and gray, turning the house into a cozy cocoon. Jihoon arrived soaked from the dash to the door, his hair plastered to his forehead, shirt clinging in ways that made Yuna's gaze linger from her spot on the stairs. Her sister fussed over him, grabbing a towel from the hall closet and draping it over his shoulders with a laugh. "You look like a drowned puppy, oppa. Sit—I'll make tea."

Yuna descended then, her steps light and unhurried, wearing a loose tank top and yoga pants that hugged her legs like a second skin. The top was one of her own this time, but chosen deliberately: thin straps, a neckline that dipped just low enough to hint at the curve beneath when she moved. "Hi, oppa," she said softly, offering him a small smile as she took the wet jacket from his hands. "Let me hang this up for you."

Jihoon nodded, rubbing the towel through his hair. "Thanks, Yuna. Appreciate it." His eyes met hers, and for a split second, they flicked downward—instinctive, uncontrollable—before snapping back up. She turned away before he could see her satisfaction, hanging the jacket on the coat rack with deliberate slowness, her back to him, shoulders rolling as if stretching out a kink.

They spent the afternoon indoors, the rain pattering against the windows like background music to their lazy plans. Her parents were napping upstairs after a long week, leaving the three of them to sprawl in the living room with board games and snacks. Yuna claimed the spot on the floor again, this time stretching out on her stomach to read the game instructions aloud, her legs kicking idly in the air behind her. The yoga pants stretched taut with each movement, and she knew—without looking— that Jihoon's position on the couch gave him a perfect view.

"Unnie, your turn," Yuna said after a round, rolling onto her side to face them, one arm propping up her head. The motion tugged her tank top askew, exposing a sliver of skin at her waist. She didn't fix it. Instead, she reached for a chip from the bowl on the table, popping it into her mouth with a slow, thoughtful chew. "Oppa, you're really good at this. What's your strategy?"

Jihoon cleared his throat, shifting in his seat. "Uh, just luck, I think. You're not bad yourself, Yuna."

Her sister snorted, oblivious as she drew a card. "Don't let her fool you—she's competitive as hell under that sweet face."

Yuna laughed, a soft, melodic sound, and let her free hand trail absently along her side, fingers brushing the exposed skin. "Only sometimes, unnie." Her eyes met Jihoon's again, holding just long enough to spark that unspoken question, before she looked away with feigned shyness.

As the game wrapped up, the rain easing into a drizzle, Yuna stood to clear the snacks. She bent to pick up a fallen die from under the table, her back arched, the tank top riding up further. When she straightened, she caught Jihoon averting his gaze, his hand rubbing the back of his neck—a tell she'd started to recognize. Satisfaction bloomed warm in her chest, but she kept her expression neutral, stacking bowls with quiet efficiency.

Dinner that night was simple—her mother's leftover stew reheated, eaten around the kitchen island with casual chatter. Yuna positioned herself next to Jihoon, close enough that their elbows brushed occasionally. Each time, she'd murmur a soft "Sorry, oppa," with a quick glance up through her lashes. By the end of the meal, the air felt thicker, charged with something unspoken, though her sister remained cheerfully unaware, planning their next outing.

When Jihoon left that evening, hugging her sister at the door, Yuna stood a step back, waving with that dimpled smile. "Bye, oppa. Drive safe."

He nodded, his eyes lingering on her a beat too long. "Will do. See you soon, Yuna."

The door closed, and Yuna turned away, the glow inside her now a steady flame. She wasn't borrowing trinkets anymore. This was bigger, riskier— and infinitely more thrilling.

But patience was still her ally. The real game had only just begun.

The humid Friday evening hung heavy in the air, the kind of sticky warmth that made skin glisten and breaths come shorter, as if the weather itself was conspiring with Yuna's long-brewing desires. Her parents' absence left the house feeling vast yet intimate, every creak of the floorboards amplified, every shadow a potential hiding spot for secrets. Miss Shin had buzzed with excitement all afternoon, prepping the kimbap with Yuna's help, chattering about how this was the first time Jihoon would see their "girls' night" vibe without the parental buffer. Yuna had smiled through it all, rolling the rice with precise fingers, her mind already several steps ahead—picturing the lace against her skin, the way her nipples would pebble under the sheer fabric, the hitch in Jihoon's breath when he finally saw her unmasked.

Jihoon arrived punctual as ever, his knock firm but polite, carrying that bakery bag like a peace offering. He looked effortlessly handsome in a fitted t-shirt that clung to his broad shoulders and jeans that hugged his thighs, his hair slightly tousled from the evening breeze. Yuna greeted him at the door alongside her sister, her sundress modest for now, but she let her eyes linger on him a beat longer than usual, tracing the line of his jaw, the vein pulsing faintly in his neck. "Oppa, you made it," she said softly, her voice a gentle caress that made him smile back, oblivious to the undercurrent.

Dinner was a slow burn in itself. They sat around the low table in the living room, cross-legged on cushions, the soju flowing freely as her sister poured round after round. The kimbap was salty and fresh, paired with kimchi that added a sharp bite, but Yuna barely tasted it—her focus was on the way Jihoon's fingers wrapped around his glass, strong and capable, the same fingers she'd imagined on her skin during those quiet nights alone. Laughter filled the room, her sister's stories growing louder, sloppier, her cheeks a deep rosy flush. Jihoon matched her drink for drink at first, his eyes sparkling with amusement, but Yuna nursed hers, staying sharp, watching as the alcohol chipped away at boundaries.

By the time the third bottle was half-empty, Miss Shin was swaying, her head lolling against Jihoon's shoulder as she giggled at nothing. "Oppa... you're so warm," she mumbled, her hand clumsily patting his chest. Yuna watched from across the table, her own cheeks warm not from the soju but from the anticipation coiling low in her belly. "Unnie, maybe you should lie down," Yuna suggested innocently, rising to clear a few plates. Her sister nodded hazily, and Jihoon helped her up, his arm steady around her waist as he guided her upstairs. Yuna listened to their footsteps, the door to her sister's room clicking shut, the low murmur of his voice soothing her into bed. She knew from experience—her sister was a lightweight; she'd be out cold for hours.

In the kitchen, Yuna moved with purpose, washing the dishes under the soft glow of the overhead light, the water's warmth nothing compared to the heat building between her thighs. She slipped upstairs briefly while Jihoon was still with her sister, changing into the babydoll nightie she'd hidden in her drawer. The black lace was exquisite against her pale skin, the sheer panels teasing glimpses of her hardened nipples, the hem so short it barely covered the curve of her ass. She let her hair down, running fingers through it to add volume, and applied a slick of cherry gloss to her lips, making them look plump and inviting. A quick spritz of vanilla perfume—her sister's favorite, borrowed of course—completed the transformation. Innocent Yuna was gone; this was the version she'd kept locked away, the one that hungered.

She positioned herself in the hallway, heart pounding with a mix of nerves and triumph, as Jihoon's footsteps echoed down the stairs. He appeared at the bottom, keys jingling in his hand, his expression relaxed until he saw her—standing there like a vision from his darkest fantasies, blocking the path to the door. His eyes widened, raking over her form: the way the lace cupped her full breasts, nipples pressing insistently against the fabric; the sheer material hinting at the shadow between her thighs; her long, toned legs on full display, ending in bare feet with painted toes. "Yuna... what the fuck?" he whispered, his voice hoarse, frozen in place as if rooted to the spot.

She stepped closer, hips swaying with deliberate seduction, her doe eyes now smoldering with intent. "Leaving so soon, oppa? The night's just starting." Her voice was a sultry whisper, laced with the innocence he knew so well, but twisted into something filthy. She reached out, her fingers trailing feather-light down his arm, feeling the goosebumps rise under her touch.

Jihoon's breath hitched, his gaze dropping to her cleavage before snapping back up, conflict warring in his eyes. "This isn't funny, Yuna. Your sister's right upstairs—she could wake up any second. I'm with her. You're... you're like a little sister to me."

Yuna's laugh was low, throaty, as she closed the distance, her body inches from his, the heat radiating between them like a live wire. She could smell his cologne mixed with the faint tang of soju, see the pulse jumping in his throat. "Little sister? Is that why you've been staring at me every time you come over? Why your eyes linger on my legs, my ass, when unnie's not looking?" Her hand slid up to his chest, palm flat against the rapid thump of his heart. "I know you want me, oppa. I've seen it in the way you shift in your seat, the way you can't stop glancing. Let me show you what you've been missing."

He swallowed hard, his hands clenching at his sides as if fighting the urge to touch her. "We can't. It's wrong—fuck, Yuna. This could ruin everything."

She pressed closer, her breasts brushing against his chest, nipples hardening further at the contact. "Wrong feels so good, though," she murmured, tilting her head to ghost her lips along his jaw, her breath hot against his skin. "Unnie's passed out—she won't hear us. And I won't tell if you don't." Her hand drifted lower, boldly cupping the growing bulge in his jeans, squeezing gently through the denim. He was already half-hard, twitching under her palm, and a low groan escaped him despite himself.

"Shit... stop," he muttered, but his body betrayed him, hips bucking slightly into her touch. His hands finally moved, gripping her waist—not to push away, but to hold her there, fingers digging into the soft lace as if anchoring himself.

Yuna smiled triumphantly against his neck, nipping lightly at the skin before pulling back to meet his gaze. "Make me stop, oppa." Her challenge hung in the air, and something snapped in him—the weeks of teasing, the stolen glances, the forbidden pull. With a guttural curse, he surged forward, crashing his lips against hers in a kiss that was all fire and desperation. It wasn't gentle; it was claiming, his tongue invading her mouth, tasting the cherry gloss and the sweetness beneath. Yuna moaned into it, her arms wrapping around his neck, fingers tangling in his hair as she kissed back with equal fervor, her body arching to press every curve against him.

His hands roamed greedily now, sliding down to cup her ass, kneading the firm flesh through the thin nightie, lifting her slightly so she could feel the full hardness of his cock grinding against her core. Yuna gasped, breaking the kiss to tilt her head back, exposing her throat, and Jihoon took the invitation, his mouth latching onto her pulse point, sucking hard enough to leave a mark—a secret bruise she'd hide with makeup tomorrow. "Oppa... yes," she whimpered, her hips rolling against him, the friction sending sparks through her already soaked pussy.

He growled against her skin, one hand slipping under the hem of the nightie, fingers tracing the edge of her lace panties. "You're so fucking wet already," he muttered, voice rough with lust as he felt the dampness soaking through. "Have you been thinking about this? Touching yourself while imagining my cock?"

Yuna nodded shamelessly, her breath coming in pants as she tugged at his shirt, pulling it up to expose his toned abs. "Every night, oppa. Dreaming of you fucking me instead of unnie. She's too vanilla— I bet she doesn't let you do half the things I will." Her words were a deliberate taunt, and they hit their mark; Jihoon's eyes darkened, his fingers shoving the panties aside to plunge two digits into her slick heat without warning.

Yuna cried out, the sound muffled as she bit her lip, her walls clenching around the intrusion. He pumped them slowly at first, curling to hit that spot inside her that made her knees buckle, his thumb circling her swollen clit with firm pressure. "Like this?" he rasped, watching her face contort in pleasure, her cheeks flushed, lips parted in ecstasy. "Tell me how it feels, Yuna. Better than your fingers?"

"So much better," she gasped, riding his hand shamelessly, her juices coating his fingers, dripping down his wrist. The wet, obscene sounds echoed in the hallway, mixing with her whimpers and his heavy breathing. She clawed at his back, nails leaving red trails through his shirt, urging him deeper. "Faster, oppa... make me cum on your fingers first."

He obliged, thrusting harder, his free hand yanking down the strap of her nightie to expose one breast, his mouth descending to capture her nipple. He sucked greedily, teeth grazing the sensitive peak, tongue flicking until she was mewling, her body trembling on the edge. The dual assault—fingers fucking her relentlessly, mouth devouring her tit—pushed her over, her orgasm crashing through her like a wave. She shuddered against him, pussy spasming around his digits, a gush of wetness soaking his hand as she whispered his name like a prayer: "Jihoon-oppa... fuck, yes!"

He didn't let her come down, withdrawing his fingers only to bring them to her lips. "Taste yourself," he commanded, voice low and dominant, and Yuna obeyed, sucking them clean with hollowed cheeks, her tongue swirling around them like she would his cock. The sight made him throb painfully in his jeans, and she felt it, her hand fumbling with his belt, zipper rasping open as she freed him.

His cock sprang out, thick and veined, the head glistening with precum, and Yuna's mouth watered at the sight. She stroked him base to tip, her grip firm, thumb smearing the bead of fluid over the slit. "So big, oppa... no wonder unnie keeps you around. But I bet she doesn't take it like I can." She dropped to her knees before he could protest, the cool floor a stark contrast to her heated skin, and took him into her mouth without preamble.

Jihoon hissed, his hand fisting in her hair as she bobbed her head, lips stretching around his girth, tongue tracing the underside. She hollowed her cheeks, sucking with enthusiasm, taking him deeper with each pass until he hit the back of her throat. Gagging slightly but not stopping, she looked up at him through lashes, eyes watering but filled with wicked delight. "Fuck, Yuna... your mouth," he groaned, hips thrusting involuntarily, fucking her face with shallow movements. Saliva dripped from the corners of her lips, making a mess, but she reveled in it, one hand cupping his balls, rolling them gently while the other stroked what she couldn't swallow.

He pulled her off after a minute, too close to the edge, hauling her up by the arms to pin her against the door. "Not yet," he muttered, hiking up her nightie and lifting her leg to wrap around his waist. His cock nudged her entrance, teasing the slick folds, and Yuna whined, grinding down in desperation. "Please, oppa... fill me. I need it."

With a single, powerful thrust, he buried himself inside her, the stretch bordering on pain but oh-so-pleasurable, her pussy fluttering around him like it was made for this. They both moaned—loud, unrestrained—as he bottomed out, his balls slapping against her ass. He paused, savoring the tight heat, forehead pressed to hers, breaths mingling. "God, you're perfect... so fucking tight. Tighter than her."

Yuna clenched deliberately, drawing another groan from him. "Say it again. Whose pussy is better?"

"Yours," he admitted through gritted teeth, starting to move—slow at first, deep rolls of his hips that made her feel every inch. "Yours, Yuna. Fuck, you feel like heaven."

The pace built, his thrusts turning punishing, slamming her back against the door with rhythmic thuds that echoed through the quiet house. Yuna's nails dug into his shoulders, legs wrapped around him now as he lifted her fully, fucking her mid-air with brute strength. Her breasts bounced with each impact, the lace chafing deliciously against her skin, and she met him thrust for thrust, hips snapping to take him deeper. "Harder... mark me, oppa. Make me yours," she begged, her voice breaking on a moan as he angled to hit her g-spot repeatedly.

Sweat slicked their bodies, the air thick with the scent of sex—musk and vanilla and arousal. Jihoon's hand found her throat, squeezing lightly, just enough to make her vision blur with pleasure, his other hand rubbing her clit in frantic circles. "Cum for me again, baby. Squeeze my cock like the slut you are."

The words sent her spiraling, her second orgasm ripping through her with intensity, body convulsing, pussy milking him as she soaked his length, her juices trickling down his thighs. "Oppa! I'm cumming... don't stop!"

He didn't, pounding through her climax, extending it until she was oversensitive, whimpering pleas mixing with sobs of ecstasy. Only then did he let go, burying deep with a roar, his cock pulsing as he filled her with hot spurts of cum, painting her walls white. They stayed locked like that, trembling, the door cool against her back, his weight pinning her as aftershocks rippled through them both.

But Yuna wasn't done. As he set her down on shaky legs, cum dripping down her inner thigh, she pushed him back toward the living room couch, her eyes gleaming with hunger. "We're not finished, oppa. Sit. Let me ride you properly—show you what borrowing really means."

Jihoon stumbled back toward the living room couch, his jeans still hanging open, cock glistening with their combined fluids as Yuna pushed him down onto the cushions with surprising strength. He landed with a soft thud, eyes locked on her like she was a siren he'd willingly drown for. The babydoll nightie was askew now, one strap hanging off her shoulder, the lace damp and clinging to her sweat-slicked skin. Cum trickled down her thigh, a lewd reminder of their hallway frenzy, but it only fueled her hunger—she wiped it up with her fingers, bringing them to her mouth and sucking them clean with a deliberate pop, her gaze never leaving his.

"Look at you, oppa," she teased, her voice husky from her earlier cries, climbing onto his lap to straddle him. His hands immediately went to her hips, gripping hard enough to leave faint bruises, but she loved it—the sting mixed with the ache between her legs. She ground down slowly, her soaked pussy sliding along his length, teasing the head with her folds but not taking him in yet. "Still hard for me? Unnie must not satisfy you like this."

He bucked up instinctively, a frustrated groan escaping him as his cock twitched against her heat. "Fuck, Yuna... you're killing me. Just ride me already." His hands slid up under the nightie, palming her breasts, thumbs rolling her nipples into stiff peaks. She arched into his touch, head falling back as jolts of pleasure shot straight to her core, her hips circling in slow, torturous grinds.

"Not so fast," she whispered, leaning down to capture his lips in a messy kiss, tasting herself on his tongue. Her nails raked down his chest, pushing his shirt up and off, exposing the lean muscles she'd admired from afar. She broke the kiss to trail her mouth lower—nipping at his collarbone, sucking a hickey into the skin just above his pec, marking him as hers in a spot his clothes would hide. "I want you begging, oppa. Tell me how much you need my pussy."

Jihoon's control was fraying, his breaths ragged as he thrust up again, the tip catching her entrance but slipping away. "Please, Yuna... I need it. Need to feel you clench around me again. You're so fucking perfect—better than anyone." His words were desperate, hands roaming to squeeze her ass, spreading her cheeks as if to urge her down.

Satisfied, Yuna lifted her hips, positioning him at her entrance, and sank down inch by inch, savoring the way he stretched her anew. The mix of his cum and her arousal made it slick, easy, but the fullness still made her gasp, walls fluttering as she bottomed out. "Ah... oppa, you're so deep," she moaned, starting to rock slowly, her hands on his shoulders for leverage. The couch creaked under them, the sound joining the wet slap of skin on skin as she picked up speed, bouncing with increasing fervor.

Jihoon thrust up to meet her, his hips snapping hard, driving deeper with each stroke. One hand tangled in her hair, pulling her down for another bruising kiss while the other slipped between them, fingers finding her clit and rubbing in tight, fast circles. Yuna's moans grew louder, unrestrained now, echoing through the empty house— "Yes, oppa! Right there... fuck me harder!" Her breasts bounced freely as she rode him like a woman possessed, the lace of her nightie chafing her sensitive nipples, adding to the overload of sensations.

He flipped them suddenly, pinning her beneath him on the couch, her legs wrapping around his waist as he took control. "My turn," he growled, pounding into her with brutal force, the angle hitting her g-spot relentlessly. Sweat dripped from his brow onto her chest, mixing with hers, and Yuna's nails scored his back, drawing thin red lines that made him hiss in pleasure-pain. "Gonna fill you up again, baby... make you drip with me all night."

The build was frantic, her third orgasm cresting like a tidal wave—body arching off the cushions, pussy spasming wildly around him as she screamed his name, soaking the couch beneath them. Jihoon followed with a guttural roar, thrusting deep one last time and emptying himself inside her, pulse after pulse until he collapsed, spent and trembling.

They lay tangled like that for long minutes, breaths syncing, the air heavy with the scent of sex. Yuna traced lazy patterns on his back, a satisfied smile curling her lips. "See, oppa? Borrowing you feels so right."

He lifted his head, chuckling weakly, but his eyes held a new possessiveness. "This isn't just borrowing anymore, Yuna. You're mine now."

And so the affair ignited fully—stolen quickies in the bathroom while her sister showered, risky car fucks in the driveway under cover of night, whispered dirty texts that made Yuna's phone buzz during family dinners. Yuna played her innocent role to perfection, borrowing glances, touches, and eventually Jihoon's heart, piece by secret piece. Her sister never suspected, too wrapped up in her own world, but Yuna knew the truth: some things, once taken, were never returned.

In the end, when Jihoon finally chose her—whispering "I love you" in the dead of night as they lay in her bed—Yuna just smiled that dimpled smile, her hand over his heart. She'd always been good at waiting. And even better at winning.
