People are a bit hard on the MC. It is difficult to view a negative review as constructive criticism when all you've received was praise so far and, well... the reviewer does not exactly mince words. Actually, it is more like she is venting her frustrations instead of offering advice. She has the right of course, but the MC likewise has the right to be annoyed by her - and that's where things would normally end, if they hadn't met in real life as well. The fact that they did is an interesting twist and I can't wait to find out what'll happen after this. The story can still go horribly wrong from here, but it has potential.
