Please, Help me! I'm looking for a yaoi about high school roommates...

I'm looking for a yaoi/ shounen ai manga that I read some time ago but can't really remember the name! It was like this there was a guy named Aki ( i'm not too sure if the name was really that it could be Akihito or samething that begins with aki...) that liked his roommate, they lived in a high school dormitory.The roomate found out about Akis´feelings and so he starts to treat him bad, he separated one side of the room on the other with adhesive tape and banned aki to go to his side, he then brings girls to his room to do sex with. The name of all the girls he brings start by aki..., so when they (the roomate and the girl) are doing sex he calls for Aki. Sorry for not being able to descrebe properly I read it some years ago so I only remember this ( and my english is not the better!)... Please help!!! and thank you very much to the ones that help me
