PLEASE HELP MEE

Hey! So there is this bl manwha which I forgot the title but the MC is black hair with like an awkward cut of hair (the reason was because he find his long hair annoying so he just cutted it of himself carelessly until he made a mistake while cutting it, leading it to being too short), and is kind of nonchalant and doesn't really understand or like he find it hard to understand human emotions (?). The ML is a blonde hottie and is the hoobae, while the MC is the sunbae! The last time I remember reading this was when the season 1 ended, and the last part of that chapter is when they got reunited unexpectedly in the MC's workplace (they've already graduated in that timeline I think because it says years later). Well, before the season ended they have lotsss of misunderstandings and eventually broke up but doesn't have any proper closure... so please help me guys if u ever know the title pf this bl manwha cause I can't find it anymoreee and I forgot to turn on the notif update for it and I saved wayyy too many manwha/manga for me to find it on my list I'm desperate enough to leave a comment here lolll
