When college student Uyun meets the quiet and introverted TA Jinhyeong, he immediately asks him out, saying he wants to get to know him more. After just three days of dating, Jinhyeong moves in with him, and that's when he starts showing a completely different wild side. All of his BL novel and comic consumption has perverted his perception of the perfect first time with his boyfriend. He's thought of it all, from doing it in the subway to having Uyun role-play as a K-pop idol. But as weird as Jinhyeong's ideas are, Uyun doesn't entirely hate it...?
