long shot but could it potentially be this?
I think it's this one: https://www.mangago.zone/read-manga/hinekure_sakura_ni_koi_ga_saku/
I forgot the name but a yaoi where the uke has crush in seme since HS and he even followed the seme to university. Both of them are good looking and popular. Turns out, the seme knows the uke has been following him because uke is stalkerish but the seme was just waiting for the uke to approach him. When seme noticed some other guy was close to uke, he decided to make first move instead.
