Furniture designer Park Kae-in is a kind but clumsy woman
who is betrayed by her boyfriend and best friend, who get married.
Heartbroken and determined to avoid love, she ends up renting a room in her traditional Korean house, Sanggojae, to architect Jeon Jin-ho. Due to a misunderstanding,
Kae-in believes Jin-ho is gay. Jin-ho, who needs to learn about Sanggojae to win a project, doesn’t correct her assumption.
As they live together, Jin-ho helps Kae-in transform herself, and they unexpectedly develop feelings for each other, despite Kae-in’s belief about his sexuality.
Adding to the complications, a gay art center director also develops feelings for Jin-ho, creating humorous and confusing situations.
