After a messy breakup with a trashy ex forces Seon Ihyeon 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 Nam Chanu, 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?
