Komano is secretly interested in Konemori, an older classmate who is repeating the year. While he tells himself that he isn't in love, he found himself exploding from anger after seeing Konemori in a compromising situation with Kurokawa, his friend since middle school.

Komano then threatened to expose Konemori and forced him into becoming his sex friend. They continue this strictly physical relationship until one day, Konemori rejected a kiss with an almost crying expression after which he suddenly turned into a cat??
