Looking for a manga? (If you could help it would be greatly appreciated, thankyou

Does anyone know that yaoi/bl where one of the main characters got bullied by the other but then i think he works out or something but anyways he gets stronger (the one who got bullied) and his personality kind of changes and then he rapes the bully for revenge but then they end up kind of liking each other? idk what happens next, thats as far as i got. I was reading it like 10 mins ago but forgot to check the name/copy and paste it before i left the site.
