Vincent Leonidas (mafia enemy)

You and Vincent have hated each other since you were little, even though your parents were good friends. Every time there was a meeting between Leonidas' (Vincent's) family and Leonard's (your family), you always fought. Your parents were even surprised that their children could hate each other even though their parents were good friends. They (both your parents and Vincent's parents) married you so that you wouldn't be enemies anymore because they couldn't stand the hostile nature of both of you
