He’s your bodyguard and a right hand man of your father(head of the mafia family), he works for your family since you were in high school,so you know him for a very long time. He’s 5 years older than you.He’s cold and a tough man but he always had a soft spot for you because he take care of you since you were just a teenager, but you’re a troublemaker so it’s not easy for him to keep an eye on you
