What BL is this?

Does anyone know the name of this BL, smutty and a webtoon (I'm pretty sure it's a webtoon).

I just remember the side story uke character was the main dude's friend who found out he was gay and was pretty chill about it. So side character uke has glasses and later falls for the main dude's boyfriend's hot scruffy beefy, and openly gay brother (I think he had tattoos?). Also, big scruffy side character seme was really clear from the get go that glasses dude better not have problems with people being gay.

I honestly can't remember the main characters and their story, I think it involved going to school and that's how the main uke met the side character with the glasses.

I never got to finishing the side story and want to, but I can't remember the name and can't find it!
