Playboy Tristan, after a fight, is forced to accept a bet: within seven days, win over the abstinent top student Arthur and snap nude photos of him. Tristan launches an over-the-top pursuit, but mistakenly believes Arthur is secretly in love with a girl of the same surname — and uses that as leverage. What he doesn't know is that the dark-bellied top student has long been deeply in love with him, and feigns submission while playing along with the misunderstanding. And so unfolds an extreme tug-of-war with the power dynamic flipped — until the playboy is utterly, completely claimed.
