hi guys.. I need help to find this yaoi manga that I've read before.. the plot goes like this...

the uke harbors a one sided love for his friend for a long time.. and there's one guy who is always staring at the uke from time to time like a stalker and that's why he became aware of him.. and then one day this stalker guy caught the uke masturbating to his friend's clothes I think?? (i'm not sure about this one.. but i'm pretty sure that he caught the uke doing something related to his feelings for his friend).. that's when the stalker guy threaten the uke and they started doing ecchi stuff together.. sometime later, the uke's friend started to notice that his friend is getting closer to this stalker guy and he didn't like that so he confess his loves for the uke.. but the uke doesn't love his friend like he used to so he turned him down and got together with the stalker guy..

sorry for my bad English.. and I appreciate it if you would help me.. thanks.. (^___^)
