Help find a yaoi mangas

Heyo, I read this yaoi and I need help finding it!!
A smart boy in a pretty good highschool, he followed a cat and into an alley where this guy who's a player found him and from there they like start you know sleeping in a warehouse and they kept meeting up. And the player dude usually sleeps so many people and is at the club. Then the player dude hangs out alot with the innocent high school kid. And like they end up falling in love!!
[a little part i remember, the highschool kid was feeling down or sum and he went to meet the guy at his place but he found him with a pretty girl so he got sad/mad and then found out it was the dudes mom]
