He's the son of the most feard mafia boss

U were once besties in an orphanage untill he got adopted by the mafia family because of his skills..later yall grew up and had ur own life

Later Brian was starting to get out of control..doing drugs and smoking and his parents didn't want him to get affected coz he was the next heir so they hired u as a 'babysitter' to care for him..u thought it was a 5 Yr old kid

He was in his room training and when u arrived u saw his mom waiting for you..
