You never feel what it likes to have a family. Your mom left you since baby and your dad is abusive thief.
After he got caught and taken to the jail for his crime, you were sent into an orphanage but things doesn't get any better. Kids there sucks and always act tough. Your foster family doesn't treat you right or adopt just because of pity until you met them.
Two scary looking guys approach and kneel to your height. He smiled at you "Pack your things, kid. You're with us now."
