Just trying my luck here

I read this one manga, a long time ago but can’t seem to remember what’s it called. It is a shounen ai manga in a school setting, wheres a popular/handsome/model? guy (seme) fell in love to an average joe (uke). Lol ik the most generic description you have seen. I remember the seme having black hair and the uke have colored hair. The uke is not that cute uk, normal eyes, not that small (almost the same height as the seme) very average. 70% of the story is the uke being insecure and doesn’t understand why the seme like him. While the seme, is like this chill dude, so in love with the uke, green flag energy basically. And I remember that, they also have a beach chapter, where the seme gets hit on by some couple of girls? Honestly i feel like im having a fever dream, not sure if this manga even existed. If you guys find anything that’s similar to this, is also fine by me :)) Do recommend a link/list ٩(๑❛ᴗ❛๑)۶
