Hi! I read this manga long time ago and I want to read it again.

There was a boy who went to a festival and got raped by another boy (or maybe an older man?) who wore a cat mask. I think he was traumatized by it. Later (when he was older) he found out his friend (who drives a delivery moped) was the one who did it because he found the mask in his house. I can't remember what happened after that.

Thank you, I hope you can help me ♥

Was it Canvas ni Kuchizuke o chapter 6-7? It was a fox mask though. 🙂

Yes, that's it! Thank you so much!
