Looking for a manga please help

Okay I can't remember alot about this, but umm it's a yaoi. A girl dies, and either only two people go to the funeral or only two stood out cause crying? This guy was the girls boyfriend, and he approaches the other guy, who seems to have been very close to the girl but he never knew him. Fast forward and he let's him stay in dead girls apartment, for free? All the while trying to solve his relationship with her. We later find out she basically prostituted her "friend" out and was abusive. Near the end the guy gets kidnapped by some other guy and forced to wear girl clothing. Actually, I'm pretty sure he says I can be your gf for you, I'll dress up like her, to stay in the house to the mc.

Anyway I know this is confused but if anyone knows what this is please reply. I thought about it the other day and not knowing the title is killing me. Also wanna reread ヾ(☆▽☆)
