I'm looking for Yaoi manga, where man starts to be guard in school.
And one night he was raped in the school, but he doesn't know who did it. And later is discovered that it was art teacher, who has falled for him and has painted painting that tells his feelings about him (Color painting.)

I don't remember how much they knew before the rape, but they had talked some.

Sorry i don't remember much of this, but today at school i remembered that manga and now i have huge erge to see it.

Isn't it chapter 4 from Zenryousei Ginsei Gakuen Monogatari 🙂 ?
