There's someone that is looking for a yaoi manga with a seme that has a white undercut (kinda like Sangwoo's hair) and an uke with black hair. They accidentally removed it from their want to read so now they can't find it. The only thing they got to read is that the uke is an introvert, and told the popular seme that he likes him, and asked him to have sex with him.
Ps, it's school stuff, so if you have read anything similar, please send the link!
