No, she's not his friend
She's actually part of the gang that's bullying him
She is not aggressive one, more like passive aggressive - never starts a fight but doesn't stop it either
She's not bad she's just an ordinary person. That's a common thing in society after all
She does not pity him but her good side will be seen soon
What a plot for a book (or film\cartoon) huh?
I AM SORRY FOR MY ENGLISH I'M TRYING :,)
