Know this manga ?

The MC is super gentle and kind . One day he found about his classmate being gay. He ignored that but after watching him he found out that his boyfriend is trash and always hits him. He couldn't ignore that so he told him to break up with him. The gay guy said they he is OK with that cuz no one else would date him . After that his wounds got worse and started skipping school . MC felt bad and visited him , and started wiping his body . at that time the boyfriend appeared and thought that he cheated on him then he hit him and left him . MC held him and said he will take responsibility and date him . Even tho he isn't gay and doesn't like him he did it out of kindness or petty. I read it long ago so I wanna know what happened next
