Looking for a yaoi manga yet again

Okay so this mangas characters remind me a lot of the ones from Bouai Friendship, but they’re different. In the beginning of the manga the main character is staying inside from gym because of bruises that his dad caused I think?? And he’s found by the love interest who sees the bruises and points them out. Then he basically blackmails the main character into having sexual with him so that he doesn’t tell anyone about the bruises. I appreciate any help you guys can give!! <3 (づ￣ ³￣)づ
