Its about a guy who confesses his love to the playboy of school the guy says yes and goes straight to his house?

They sleep with each other.
They stay in bed i think for 3 days or something

They guy knows the player doesn't date but the player likes having sex with him.

Als a third guy likes the guy (not the player )

Last i know is that the player invits the guy to a luxery hotel (almost at the end of the manga

Playboy is seme
Third guy was i think just clasmate/friend
But i think the playboy only slept with women but got interest in sleeping with a guy

It reminds me of Overdose but I'm not sure it fits completely.

Also next time instead of making a new thread bump up your old one, but only after 7 days has passed http://www.mangaupdates.com/showtopic.php?tid=44767&page=1#post629088

So keep in mind I'm filled with typos
