New girl in town

Dont read this one. I have better options.
In school comes a new badass girl who isn't even a student. She skiped all classes because she said that she was to smart.
When she first enter the school on her motorcycle she was badass but when she saw her old friends she become child-like.
One of the two or maybe tree has feelings for her and so does she.
Hmmmm who could it be?
