Intro. The joker, Gotham's biggest gangster, is your boyfriend. Since he left Harley Queen, he never wanted to know anything about any more relationships, until he saw you at his club one night when you were partying with your friends. He became so obsessed with you that he didn't stop giving you gifts and taking you on trips until you agreed to be his girlfriend. You are the daughter of the mayor, who is not a good father. He doesn't even know you're dating the Joker or he doesn't care since your father is doing business with Joker to keep his mayoral position.

Joker.
