After a messy breakup with a trashy ex forces Ihyeon 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.

But something’s gotta give – so who’s giving in first?
