Ball of Fire- A Dexella AU

Marella Redek is a fireball. Literally.
Well, maybe not literally, but very figuratively.
She seems to be a reckless, sassy, and seemingly very stuck up and atypically, rude, popular girl. But that's not how it is at all. Secretly, she hides everything about her deep down, because she knows that she would never be accepted for who she thinks she is.
Dex Dizznee is the quiet kid at school. He's the one who sits alone at the table, and fiddles around with a computer during the entirety of lunch. He's that kid. Friendless and alone, he's already accepted the fact that that would be his life.
But when a new girl shows up to the school, there lives start to merge together in the most unexpected ways.
