beta
I've been trying to look for this specific manwha for a while, and all I can remember is that the seme is tutoring the uke and he is older, has black hair, wears glasses, is very mean to the uke and treats him like an idiot. The uke is blonde and has a big crush (I think?) on him so he endures it and the last chapter I remember reading, the uke was leaving to another place but the seme stopped him and apologized to him or something.
noo it's not this one
it's refreshing to see that they lost their baby face and look like adults after the timeskip
