Okay, so I have been spending days trying to figure out this manga, but I cant remember. The story goes like:

The uke goes to a party and calls the seme (by the way they are a couple), the seme says that he should not drink because when he does he always ends up cheating. The uke says he wont cheat on the seme, but meets this sexy man and has sex with him. After that, the uke goes home and apologizes and the seme forgives him but then the uke meets the other guy again and starts to fall for him. I don't remember how it ends, but I hope it rings a bell to someone. 😕 🙂

Thanks in advance. 🙂
