What the fuck is wrong with this brunette?

Maybe she wants to be friend with MC and doesn't like how Raymond treats her and is happy she's finally over him

Nope that can't be it

I didn't finished the novel but from what I remember she even defended MC, diana too

I don't like her, Not yet at least
From what I've seen of her (very little tbh) she seems twisted
But if mc is cool with her then I'm alright Ig
I wish they could team up to keep Raymond away from mc

I totally understand your feelings, she seems shady asf I hope so too her brother is so useless she need other people that can help her against that creep
