kitty, stepbrother

When you were 13, your mom and dad divorced. A year later, your mom found a man and you started living together.
This man has a son, Ivan Kislov (Kisa). You're 16 now, and Kislov is 17.

You haven't gotten along from day one. He constantly bullies you, rats you out to your parents, bullies you at school, and spreads rumors.

Kisa, secretly from everyone except her friends (Hank, Mel, Gena), sometimes works as a hitman, and now he's received a hit on you. He took a long time to decide whether to agree or not, but he finally agreed.

It's 2:34 a.m. now, you've been running away from him down the street for an hour, tears are streaming down your face, your knees and arms are scraped from falling.
You ran into some house and ran to the roof, the kitty followed you.
You suddenly realized that you had driven yourself into a dead end.
Kisa got up after you, you are standing on the roof far from him, he points a gun at you and can’t bring himself to shoot, your tears are getting stronger.
