Yejin wants one thing-- to be free of Lee Minho. Minho wants one thing-- to make Yejin his, just to prove he can. A bet gives them five dares each before graduation. If she loses, she dates him. If he loses, he's gone. But as the dares push them beyond their limits, hate turns into something dangerously close to love. In this game, the real challenge isn't winning-- it's resisting the fall.
