Lost yaoi

Another one I wanna find : manga begins with bottom breaking up with his cheating bastard boyfriend in the street, and then a (clean) male underwear falls on his head. He meets the owner of this underwear, the top, who is older than him. They continue to meet and start going out, but bottom is insecure cause he's gay but not the top and top doesn't touch him. But of course then everything goes well, I remember bottom working in a bar and top goes there after work by chance while they were fighting, which is where they talk and resolve anything.
It was a very good yaoi I loved it.
Does someone know?
