    Chapter List

    When going on his daily morning runs, it was extremely common to have zero interactions with anyone else. Part of the reason for that was there weren’t many people up that early in the day, but what was probably a bigger contributing factor was the tendency Korean people to mind their own business. Not that Seojun minded; in fact, he liked it that way. Being alone in his thoughts while feeling the wind through his hair and on his skin and his feet pushing off against the pavement to propel his body forward was all the reason he needed to partake in this daily ritual.

    So, when a sudden yank to his arm sent him tumbling into an alleyway, to say that he was shocked was an understatement. In fact, shocked was probably the wrong word to use: terrified was more appropriate, at least initially. What diffused that feeling was faceplanting into a pillowy surface, only realizing what it was when his arms hastily wrapped around a smaller frame, a pair of shoulders.

    Seojun pulled himself back in a hurry, stumbling over his words as he stammered out a, “Sorry!”

    “Sorr—” Now that he was back firmly on his feet, he could see the person who had abruptly pulled him off the sidewalk: a young woman, an insanely attractive young woman, wearing a confused yet bright smile, who stood at perhaps around Sunny’s height with a bust to match. “Why did you apologize? I’m the one who suddenly pulled you over.”

    “Um, no, it was because—” now that he thought about it, was this woman a succubus? He had been trying to get the idea out of his head, that all insanely attractive women were succubae or otherwise demonesses, but the fact that she did what she did and seemed to recognize him added to his suspicion. “—I faceplanted into your, um,” his eyes darted to her impressive rack, diverting his gaze just as quickly, “yeah. Sorry about that.”

    The woman, or succubus, paused for a second, maintaining the same confused expression before letting out a giggle that Seojun could only describe as magical. His mood wasn’t bad at all, and in fact was pretty good after having had the chance to feel the woman’s ample bosom against his face, even if by accident, but hearing the almost musical sound made his mood improve tenfold, it felt. Subconsciously, a smile spread across his lips as she replied, “You’re interesting. But, more importantly: do you wanna prank Taeyeon?”

    That all but confirmed that this was a succubus he was talking to, and from her approachable demeanor, he surmised she was friendly. Maybe the encounter with Jessica made him drop his guard too much … but whether that was the case or not, the current problem at hand as something else. “Um, ‘prank’? How?”

    “I want to surprise her into thinking that I manifested my Trait as a brainwashing ability. So, basically, all you’ll have to do is listen to my commands.”

    Well, that answered one question, but didn’t answer perhaps the most pressing ones. “Sorry, first of all, can I have your name?”

    “Oh!” Realizing her mistake, the succubus let out a sheepish chuckle. “Sorry! I was so excited when I saw you on my way over to Taeyeon’s house that I forgot my basic manners. I’m Yeri, I’m an offspring of Taeyeon.”

    Hm? ‘Offspring’? Seojun was under the impression that succubae couldn’t get pregnant. Was he mistaken?

    “Offspring…?”

    “Yep! She made me into a succubus a few decades ago.” Ah, so that’s what she meant. Not that Taeyeon gave birth to her, but that she transformed her into a succubus…?

    Seojun never really gave much thought to how it was that succubae existed, mostly because every encounter with one quickly devolved into fucking, but now that he gave it some thought, it made sense that they were derived originally normal women. That led him to the curious topic of how a succubus gets created … maybe through a ritual similar to the Servant Ritual he had partaken in twice?

    “And I suppose you know that I’m Taeyeon’s servant, then?” Yeri nodded. “Why did you want to prank her?”

    “Because it’s fun! Why else?”

    Seojun did admit, the idea of catching the usually in-control and stoic demoness flustered and off guard did seem interesting. But, the other reason for wanting to follow along was the infectious energy that Yeri was exuding. With how brightly she was smiling and just the positive energy that seemed to emanate from her relatively small frame, it was hard not to comply with her request.

    “I’ll do it.”

    She let out an excited squeal in response. “I promise not to tell you to do anything too crazy,” she said, stopping short upon grabbing his hand.

    “Hm? Is something wrong?”

    “Oh…” Did he do something? Was his hand sweaty? Seojun’s mind buzzed with all the possible reasons for Yeri’s sudden pause, but as abruptly it happened, so too did she recover. “No, nothing’s wrong.” Having recovered, she didn’t go back to her energetic, peppy self that she introduced to Seojun. It was a deeper, more sexual tone that she had switched to, and Seojun could guess as to why that was.

    But it wasn’t like he could act on it out here in public. It was only when they returned home that he began to wonder about her slight change in demeanor, but that thought went by the wayside when Yeri started giving him instruction on how to act.

    Seojun wasn’t much of an actor, but if all there was to it was to obey Yeri’s commands, how hard could it be?

    “I’m home~”

    “Stay here for now,” Yeri whispered to him, jumping up from the couch.

    “Taeyeon!”

    “Oh, Yeri, you’re here already?” the older demoness said, greeting her offspring with a hug.

    “Yep! You’ll never guess what happened recently!”

    Taeyeon laughed. “Wow, you’re more energetic than usual. Have you met Seojun already?”

    “Oh! Yep, that’s part of what I wanted to show you!” Taeyeon pursed her lips and pulled eyebrows together in confusion. “Seojun, you can come out now!”

    He got up, walking towards the two with as neutral of a facial expression as he could maintain. Of all the things they talked about, how his default modus operandi should be wasn’t among those, so he could only hope Yeri was fine with his decision of using a neutral expression. Although, thinking about it a bit more, maybe it was a bad decision when he thought about the commands Yeri might get him to do. “Yes, Miss Yeri?”

    “Seojun?” Taeyeon’s eyes darted between Yeri and Seojun as she pulled away from the hug. “How was your morning run?” Seojun, however, kept his gaze on Yeri, the pleasant, customer service smile similarly directed at her. “Seojun?”

    “Go ahead and answer Taeyeon, Seojun.”

    He turned to his Mistress and answered, “It was pretty good, Miss Taeyeon. I had the good fortune of running into Miss Yeri during it which made my morning run all the better.”

    Taeyeon let out a hearty laugh at that. “I see ‘Miss Yeri’ has grown on you. Are you doing some kind of roleplay, calling me ‘Miss Taeyeon’? I didn’t interrupt anything, did I?”

    “No! Who do you take me for, Taeyeon?”

    “Are you or are you not a succubus who feeds on any and every guy she can find?”

    Yeri opened her mouth to defend herself but no words came out. Taeyeon cocked her eyebrow, only to be met with an indignant, “But, it all tastes so good! I think the better question is how you can resist not feeding off every guy you see. You know, it took a lot of restraint to not feed off anyone when coming over here.”

    Taeyeon smiled in response, a kind of gentle smile a mother might direct at her daughter after catching her sneakily eating from the cookie jar. “Yes, I’m proud of you, but an offspring of mine can do better. Feeding with no regards to quality is the very reason why your Trait has yet to manifest, Yeri-ah.”

    “Oh, that’s what I wanted to tell you! My Trait did manifest!”

    Again, Taeyeon cocked her eyebrow. “Oh?”

    “Yeah! See?” she said, pointing at Seojun. “Let me demonstrate: Seojun, do ten squats.”

    Seojun laughed to himself at the rather strange request but obeyed nonetheless, not paying much mind to the onlooking Taeyeon as he did the brief exercise before standing back up and returning his gaze on Yeri.

    “So your Trait is to coerce people into doing exercise? Maybe I should hire you as a personal trainer…”

    “No!” Seojun nearly laughed at Taeyeon’s remark, and again when Taeyeon let out her full, deeper laugh. “My Trait is the ability to brainwash people.”

    “Ah, is that so? What’s the activation condition?”

    “It’s touching—touching while exchanging bodily fluids.”

    Taeyeon nodded, eyes glazing over as if in deep thought before responding, “On second thought, hiring you would be a problem. I can’t have you feeding off every man who comes to work out at my gym.”

    “I wouldn’t—I mean, aren’t you proud of me?”

    “Hm?” Taeyeon’s eyes refocused onto the brightly smiling succubus in front of her. “Of course! Good job! That’s a very interesting Trait you acquired, but make sure to not force people to do things like wire their entire bank account to you, ok?”
