Looking for a yaoi!!

Okay so i'm looking for a yaoi but don't remember much so here it is. Person A lives in an apartment next to Person B, Person A also goes to the same school/class as Person B. Person B is in an abusive relationship with a guy and person a finds out, anyway i think person b breaks up with him (the abusive guy) and both person a and b become close friends because they are both gay.... thats all i remember though i think one guy was blonde and the other had black hair though i'm not sure. If anyone knows it i'd be very happy because i've been looking for it for days.
