Help! I'm finding a Yaoi manga!

So the setting is everybody is a university student. Uke had a crush with his best friend but he had a gf. Uke lived next door to seme.
Uke's crush borrowed uke's room to have sex with his gf. Uke agreed. But then he had to stay somewhere so he asked seme.

That was when they had sex, seme thought uke loved him because there was one day uke stared at seme's beer hard.

Btw seme is a playboy and brings lots of girls to have sex in his room, and it bothers uke a lot.
