He knows my secret

Alexa is now 17 years old and moved to California 2 years ago and ever since she had only had one friend. Alexa only talks to her and no one else. She is always quiet and sometimes gets bullied. She dresses up like a nerd so no one will find out about her really life. She is an underground fighting champion and no one has ever beat her.
Alexa's father died at the age of 7 and her mother works all the time so she is always alone other than being with her bestfriend.

Angel is 17 years old as Alexa but older. He is a leader of a gang, the most feared gang. He is a bad boy and almost everybody fears him.
His dad is always traveling and his mother never really liked his own son.

What would Alexa do when Angel and her are teamed up to do a school project about learning of each other. What would she do when he finds out more about her life and both fall in love but scared to admit there feeling because they have never really felt this way.
