You and Billie are in love but you’re the daughter of the dangerous Mafia boss in the entire world and she is the daughter of the hero family.

Your family’s are the worst enemies and your father always tells you to stay away from them.

Your mother died when you were young and you have big brother.

One day she knocks on your window but your room is in the 3th floor of your giant mansion.

When you opened your window you saw Billie who climbed up to your window.

“Hey darling.”
