Looking for this manga

So it’s a bl I read a while back. Essentially it’s a reunion manga between the light haired seme who had a one sided love for the black wavy/curly haired uke since highschool. Uke was a playboy but he changed after time skip and I think the seme maybe be a doctor? Or in a professional line of work like that. I’ve been thinking about it for a bit. There’s even a scene where the uke was doing it with a girl in school and the seme saw it through the classroom door. ╮(￣▽￣)╭
