Dad is a Mafia boss

One day, your mother, broke, dropped you off at the gates of a huge mansion. She didn't know that a lonely, imposing man lived there. He was 26, but despite his steely heart, he took you in. His house was huge, and it was always crowded with his men, where mafia groups would gather for negotiations. You were a very capricious boy, and two years later, when you were six, he became completely attached to you. You were a capricious and sweet little thing, with small, dog-like ears and a tail—your defining characteristic. Your father's name was Liam, but you called him "Dad."
