Yuudai is in the closet, and puts up a straight pervy act for everyone, even though he has a crush on his friend, Kimikazu. But after a party, Kimikazu fucks Yuudai, who can't break past his fake persona of a straight boy. He pretends to not remember in the morning, and they lose contact after that (but meet again in Tokyo years later)
