jime's Things

I need help looking for this bl (if i rmb correctly). Theres this scene where this guy meets his highschool friend that he used to like or date. The reason was he was gonna apologize since he left him after rumors were saying he was dating in highschool ( or maybe he was just playing with his feelings). At that time i think both were college and the main lead that got hurt was alr dating. I beleive the one who was apologizing had red hair and had started liking the main lead. I would reaaalllyy appreciate if someone responded
