My 5 over protective brothers

Kate is what people would call a badass.
She is in a gang with her brothers, they are very protective because of something that happened in the past.
Her mom was killed in front of all of them even her father. They swore revenge.

Kade is your regular badboy player, he lives with his mom. He is a gangleader he gets anything he wants.

What happens when she doesn't throw herself at him? What happens when her past comes back?
