in my opinion, it was so hard to believe that there’s a way he’s a main lead. maybe if he ended up with jae-i at the end he could’ve been considered a main lead, but he didn’t. other than the romance plot, the whole reason he came to the school was to get revenge for his brother, but he ended up barely doing anything. his presence honestly just seemed SO pointless. the romance between the teacher and woojin also seemed kinda pointless. they were dating and everything, but their breakup honestly seemed so rushed too. like one second they were “in love” but the next second they were broken up because woojin suddenly liked hera?? if they were going to do something of that sort, they should’ve at least added at least a bit of a plot. i swear she was only added to the drama to be an nuisance to viewers. this show didn’t have a plot whatsoever.
