Shogo Izumi, who has changed high schools and is now commuting from his aunt's house, sees Mina and Rei (Akira), whom he met on the train on the way to school, having sex in the school nurse's room. An amazing fact I learned there! Rei was a hermaphrodite, and she had both a pussy and a penis. Rei has a history of rape and hates men, and Mina loves Rei. And Shogo falls in love with both of them. Can a love triangle be established? A slightly sad and unusual love story.
