Park Kae In (played by Son Ye Jin), a furniture designer and the daughter of a famous architect, is kind, impulsive, and a complete slob in her personal habits. Naive and trusting, she's stayed with the same man, Chang-ryul, for years, ignoring all the poor treatment she's received at his hands. When he dumps her in the worst possible circumstances, she's heartbroken, and determined to never take a chance on a man again. Enter Jeon Jin Ho (Lee Min Ho), straightlaced (and straight) architect who needs to scout out her house for his latest business deal.
After Kae In takes him as gay during an early encounter, Jin Ho sees his opportunity and decides to pretend to be gay in order to move in with her. Once there, he gradually embarks on a mission to make over the inveterate tomboy/slob, but in all the mayhem of the makeover and hiding his true orientation, the unexpected happens and the perfectionist architect begins to fall for her. What will happen when the man who's pretending to be gay and the woman who thinks he's gay develop feelings for each other?
