After a messy breakup with a trashy ex forces hyeon Seon to take a three-year-long break from college, the last thing she wants to do upon her not-so-inconspicuous return is to dive straight into another relationship. But then comes Chanu Nam, a notorious bad boy who finds himself having a vested interest in Ihyeon. And suddenly, what was supposed to be a low-key senior year is looking like it's going to be anything but. The harder Ihyeon pushes Chanu away, the stronger he keeps pulling her back. But something's gotta give - so who's giving in first?
