I wish she gave up on him and did 180 in treating him. Not many things are scarier than heartbroken women.
If people started treating him like a freak and messing with him for fun instead of ignoring him, then we'd at least have rather believable failed romance and bullying story. Could get MC to work his way up from there, maybe even end with a different girl. Sadly this is romcom, so we all know what's likely at the end.
yeah - the tone's all wrong for too hard of a shift into actual bullying and despair, including the "feel" of the artwork itself, I think.
It would be very interesting, yes - honestly seeing a "bad ending" would be super intriguing, though I imagine it would
not be well-received and thus would be professional suicide on the part of the author to go that route, and again the vibes do not lean that direction thus far.
My own thoughts/prediction is a lesser version of that, at least - that she will start paying less attention to him, he'll think "finally" but then continue getting pangs in his chest whenever he sees her talking to someone else. It'll slowly eat away at him as he starts isolating even more (not like he has friends, but leaving the class to eat lunch, not engaging whatsoever with anyone when they try to talk to him, become a self-ostracizing outcast that gets whispered about by the class) - and the whole time, even as she distances herself, the FL will still be looking out for him, maybe toning her own behavior down around others to try and modulate how she's been around the ML up to this point.
Maybe he gets into a spot of real trouble (not like bullying, but something that would set off his germaphobe alarms in a bad way, like tripping into a mud puddle & having a major panic attack, or getting sick and ending up in a bad way at home), and she'll come to his rescue. She'll handle it well, trying her best to not be the usual loud/energetic version of herself, and they are forced into hanging out for a day or something - and he notices the change, and realizes that she's trying for his sake - and that makes him make an effort to confront
all of his feelings toward her and himself.
And that progresses their relationship forward, to whatever end the author wishes (if this is a finite series with a predetermined end point, I could see it ending right around there with him confessing his feelings and them getting together, seeking to better understand and balance out the "extremes" of the other).
I guess we'll see whether I'm at all in the ballpark with any of that.
