Physical therapist Kim Dan has been down on his luck for as long as he can remember. Between an ailing grandmother, loansharks and an old boss making it impossible for him to find a decent job. Running oit of options and barely making it every month, naturally it feels like a dream come true when he's finally hired to treat the top MMA fighhter, Joo Jaekyung, the offer seems more tempting when the MMA fighter personally calls Kim Dan a night before one of his matches while offering him five thousand dollars. He claims to have a 'jinx' where he is in need of a particular type of treatment a night before his official matches. But its something Kim Dan is not prepared for.
You see, Joo Jaekyung is a beast while in the ring but he is a real moster in the bedroom. Kim Dan is not sure if he can survive Joo Jaekyung at his most primal. Nevertheless, the promise of a high pay makes Kim Dan accept this ill fated deal.
Could a night together with Kim Dan help break this jinx? And what awaits both of them down this road?
