Hey, I'm trying to find a manga where the uke is going out with a straight/married man, and there are problems in their relationship. Seme is uke's friend and he's secretly in love with him. I remember a scene where seme and uke are together in a flat, uke goes to the hallway to answer a phone call from the straight man who says he's sorry for the things he did and he wants uke back etc etc. Uke starts crying because he realizes that he loves seme, then seme walks to the hallway, sees uke crying and grabs the phone to shout at the other man for making uke cry. I think they get together in the end?

I know this one. It's in a Asou Mitsuaki's manga... Wait a bit.

Found it: Ch.4 of Tear Drop.

Thank you so much!
