Anyways I'm trying to find a manga I read years ago...
So basically from what I can remember, everyday our main man goes to this abandoned school right next to his school (?) and masturbates in the bathroom. He's caught by another schoolmate that blackmails him. I know it sounds a lot like onani master kurosawa ᵇᵘᵗ ᶦᵗ'ˢ ᵍᵃʸ.
