The birthday duo celebrates in a different type of way.

The day gets spent in as many places as possible that don't involve the apartment.

After a drunken night at a new nightclub, you indulge in more than just alcohol.

Winter break is here, and Yujin plans to take full advantage of the time off by keeping your full attention on her.

The best Christmas present isn't under the tree—it's in your bed.

With Yujin busy with exams, the apartment becomes off-limits—so Wonyoung needs a brand new place for her own "studying".

Wonyoung lets her jealousy get out of hand, and does what she can to pry your attention away from Yujin to keep it all to herself.

It's almost Christmas, and Wonyoung is as needy as ever.

After a much needed dinner outing, the night gets started and seemingly never ends.

Starting the day in Yujin's sheets, breakfast turns into a meal that never ends.

Milkshakes with your roommate Jang Wonyoung somehow turns into a disaster, and you're left dealing with the consequences.

Following a desperate, violent encounter with Karina, a heavily drugged Wonbin helplessly watches the remaining Houses fall to the billionaires. Paralyzed, he is forced to witness Wonyoung take the stage for her devastating grand finale.

In the heat of the auction, emotional walls crumble between Wonbin and Yujin, leading to a public display of passion and a heartbreaking loss as the bidding war claims its first victims.

Trapped in the game, Wonbin is forced to participate as a Jack and confronts his past heartbreak, while a drug-fueled haze leads to an intense encounter and a stunning reveal on the auction stage.

The Blackjack Auction begins with the House of Hearts, where Wonbin witnesses terrifying performances and bids to save a terrified idol from a dark fate, leading to a shocking abduction.
