Anoko wa Shoujo no Furi wo shite

Kokiyo Kakei is a new teacher assigned to an all-girls high school, even though he has certain "reasons" for not being able to relate to women… When Kakei meets Sei Hiruma, the "prince" of the school, who just got out of the hospital after an injury, Kakei's life as a teacher changes drastically… If they had never met, things would not have been broken... This is a not-love story between two queer people.
