Looking for a story

I feel like I might have made this up or something I can't find it anywhere. It's a college story about a playboy (seme) who gets asked out a lot and he always says yes but never develops true feelings so the girls dump him. One day a flustered energetic puppy type uke asks him out and the playboy says yes. The uke has no expectations and is just happy to be dating him. The seme ends up falling in love. I think the fact the uke has no expectations becomes a bit of a problem. And I believe the playboy did not know who the uke was before they started dating but obviously the uke did know and had a crush on him and decided to take his shot. It's NOT seven days or date me too. I have no idea if it was a manga or manhwa can't remember any colors or what the characters looked like. It also could be a live action bl but again not sure.
