helix's Favorite

Can someone help me find a yaoi manga? I can't remember the name of it but I remember that the uke was depressed at a bar and a guy comes up to him. They start talking about why he's depressed and it turns out that the the guy was the uke's boyfriend's first man and he told the uke that he alone couldn't satisfy the seme, so he came up with a way to test it. The uke handcuffed the seme to a bar above the bed and walked out handing the guy the key and the guy proceeds to rape him and when he doesn't moan the guy pulls out a knife and starts cutting him to make him scream so that the uke thinks he is enjoying himself and when he leaves the uke come in to find him badly injured. After he gets out of the hospital they make up and have sex and I remember that the uke always wore leather outfits.
