She only started doing that at the end because shes never had romantic feelings for anyone before so she lashed out onto him. Thats a defense mechanism when people are unsure of something foreign to them. Thats the only time other than that in the beginning she was very nice and good to him. She let a stranger room with her, thats a very generous act to do. She’s developing as a character. If you dont like character progression then idk what to tell you.
Okay, she's nice at first, but in the end, she treats him badly because she's jealous and thinks he's dating someone else.
I will not appreciate being talked like that for no reason.

I do not like her character, she treats him like shit, and he is too kind
