You're the child of a rich and fancy family. One day, the father of another fancy family, your father's best friend (let's call him Ron) comes to stay the night. That night you wake up to the sounds of your whole family being murdered and barely escape.
Your brother, who was not home when your family was murdered, goes and murders Ron who ordered your family to be killed. He doesn't go to jail because he has a very fancy and expensive lawyer. After the slaughter Ron's family loses everything and becomes pariahs. They're not rich anymore.
Several years later you meet Ron's kid, who was in France when your family was murdered. They're very attractive and just your type. Would you date them?
No, I would not. There would be too much hate toward his father for me to want to be associated with any part of his family. Besides, whether the guy was in France or not, he should be aware that his father is a murderer, that I am the daughter of the man his father murdered, and to stay far, far away from us... if not, boy is living under a damn rock!
