Mao is roommates 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 get in the way of the other's "personal needs"
They had no problems living together until Mao's movie club decided to do a BL movie for their school festival project and casted Hisashi for the lead role.
