I am not seeing everyone's problem with Misha. Yes, she made a mistake in her treatment of Magnus, but please note what they both had to deal with in Eugene the "hero". It is entirely possible that she simply wasn't able to argue with or contradict the things that Eugene would say about Magnus due to Eugene's "hero" status, and it doesn't help that Magnus let Eugene walk all over him for such a long time himself. Magnus admits that Misha was not primarily at fault for his treatment in the party, and admits that he himself should have stood up for his thoughts and instincts. Misha has OBVIOUSLY had a thing for Magnus since the beginning of the manga, and even if she went about it in the wrong way, she did seem to genuinely want to help him stand up for himself and fulfill his potential. We can see in earlier chapters that Misha is proud of Magnus for continuing to fight and help people, and is sincere in her apology and acknowledgement that she wronged him. I don't see that particular scene as a "rejection", but as a chance for Misha to redeem herself in Magnus's eyes and gain his trust. She is not a "thot", she is a sweet girl who was put into an unfortunate situation.
