I remember reading a bl manga about a sadist that beats his masochists partners so bad that they don't sleep with him no more, and his crush from highschool -I think- confessed to him that he liked him, so they started dating and he tried his best not to show his sadist side, but he couldn't take so they broke up but stayed as friends, then someone attacked his ex and stabbed him with a knife then all he wished for is for him to be okay and they got together and he somehow lost his sadist side and felt good with normal sex or smthn?? HELP I CAN'T REMEMBER THE MANGA'S NAME!!
Not sure but I went through my read list.
