Help! Looking for a yaoi manga!

It was about a guy who takes care of this other guy when he would get extremely depressed and suicidal and would stop showing up to work.
They are really in a relationship and fuck though.
The depressed dude was an author, I think. And he was obsessed with the other dude. Like a stalker.
Before they were together he was stalking the guy and the guy thought the stalker dude was poor but he finds out he's an author and actually very rich.

PLEASE I DIDN'T EVEN READ IT THAT LONG AGO. Help me find this yaoi!!!
