I mean they don't know her situation just like how she didn't know how many knights died during the mission her father sent them to.
Still no reason to have that attitude towards her tho unless she was being a bitch but not really
If I were one of the knights I'd feel the same too ngl. Why should I be buddy buddy with the daughter of the person who sent us to a deadly mission where I lost a bunch of my comrades. None of it is Maxi's fault but it's human nature to behave like that until they get to know someone.
I'm not liking those knights. What a bunch of assholes
