Kim Dan, a struggling physical therapist, has been facing a series of financial and personal setbacks. With his grandmother’s illness, persistent loan sharks, and a difficult ex-boss hindering his job search, Dan feels like he’s at the end of his rope. So when he’s offered a job treating the highly paid MMA fighter Joo Jaekyung, it’s like a ray of hope in the darkness.
But things take a surprising turn when Jaekyung asks Dan for a particular type of treatment the night before a big match, offering five thousand dollars in return. The treatment is something Dan isn’t quite prepared for, especially when he discovers that Jaekyung’s “jinx” is related to his performance in the bedroom.
Despite his reservations, Dan agrees to the offer because he desperately needs the money. As the night unfolds, Dan discovers that Jaekyung is not only a fierce fighter but also a rough lover. Will Dan be able to survive the night with Jaekyung at his most primal, and could their encounter be the key to breaking Jaekyung’s jinx once and for all?
