The Cop and the Criminal

This is a human au

Red is a small 17 year old boy living in a big world. His younger brother Edge is only 16, and already the biggest crime boss in the city. Life is hard for Red. He dropped out of high school and does the dirty work for his brother.

Stretch is a tall young man who's getting everything he ever wanted. He's a 25 year old police officer who's good at what he does. Stretch has a loving younger brother and a good sized apartment.

What happens when 2 people from completely different worlds cross paths?

(Also I know that Stretch and Red are supposed to be the same age, but I wanted Red to be younger)
