She's Stronger Than You Think

DISCLAIMER: I am not part of a gang and I don't encourage you to join one either. This is just something I am experimenting with.

Matt is the leader of a powerful gang, but they're more like family to him. His cousin, (y/n), and friends, Dan and Sean, are also part of that gang.
Nate, Felix, and Mark are part of a rival gang, who are just as powerful.
What happens when the two groups cross paths? And what will happen when Matt borrows too much money, putting his friends and family in danger?
