Hiyori Kohinata. She's my aunt, my family and my teacher. The only thing she cannot be is my lover. But I still can't forgive any other man to have sex with her. She's sweet, and can be easily charmed by men. I have to watch her constantly. There are rivals everywhere.
Gym teacher, classmate, pervert guy all in the same school... I 've got one month to graduation. One month to keep her faithful.
Busy.
