Thanks so much. I read it when it had ine chapter out and forgot its name. Thanks again
happy to help! :D
First of all its a yaoi manga. It takes place in a school setting. The uke never goes to do sport class because of his scars which he obtained via abuse from his dad. The seme finds this out and blackmails the uke. Turns out the seme also had a traumatic past which left him a big scar. I think his scar was from a burn or something. The uke is black haired and the seme is white or blond haired.
