the Slytherin and the Griffindor

Once friends until they were separated by a hat.
They started hating each other just because of some people's beliefs.
After Casey started flirting with other boys she realized just how much she liked her childhood best friend Draco Malfoy.
It'd be complicated but she'd figure out how to make him fall for her.
What she didn't know is he was trying to do the exact same thing.
