1-2. Waraibanashi no You da
3. Akogare no H, Hikaru Hoshi
4. Kyou wa Me kara
5. Hanabi no Koro
6. Shukudai wa Saishuu H ni Owaranai

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.
