So for the entirety of the story the FMC has abused her power to negate and reverse any circumstances that even vaguely inconvenience her's status but NOW she won't negate and reverse the various damages imparted because of two of her classmates coming to literal blows over her (and a third person essentially forcing their way into her home)? My hate for this wretched saga is almost matched by my disappointment in it.
Remember the way he got dragged into her world? Being threatened with prison on a false rape accusation? We know she wasn't serious about it...but he doesn't. And she's used that to be completely unreasonable with him ever since. (And she was serious about a lot of that.)
It can't be easy to reconcile her apparent (to him) toxicity with his ever-increasing romantic attachment to her. I wouldn't wanna admit it to myself, either.
