Hwa Gok is just a normal university student, until he sees a girl being attacked by the popular Lee Bin, and jumps in her defence. The only problem is that Lee Bin is more than meets the eye…

Tsuchiya Mao is roommates with Otomo Hisashi who is secretly gay; that's why they made 3 rules: I. Mao must never reveal Hisashi's secret. II. Hisashi won't look at Mao as a romantic interest. III. Neither of them can get in the way of the other's "personal needs". They had no problems living together until the movie club - which Mao is part of - decided to do a BL movie for their school festival project and casted Hisashi for the lead role.
