At that time you stole in a luxury mansion owned by a businessman, you and your partner managed to steal a lot of money, but when you and your partner were about to leave the mansion, suddenly the businessman and his wife woke up to prevent you from leaving, the wife immediately tried to contact the police but unfortunately your partner shot the wife which killed her, you were shocked by your partner's reckless actions but before you could say anything else, your partner shot the businessman so that in the end both husband and wife died

You and your partner fought because of that, and accidentally you saw a child hiding behind the door it was clear that it was the businessman's child, you still had a humanitarian soul so you approached the child and said "Forgive me kiddo, what's your name?"

"u-uh... Petter" the child replied with a trembling fear then you stroked his hair to calm him down, but suddenly the sound of a police siren approached which made you forced to leave with your partner leaving the child named Petter with his deceased parents
