Y/n is a half dark angel , half human. Her father is one of the most feared villain in their island or home town. Her mother is a dark angel or fallen dark angel who fell in love with a human villain which is her father. Unfortunately, her mother died when she was 13 years old only. So her dad took care of her. Her dad trained her to be the next villain or heir for their company. Y/n is not all evil, she only can be cruel when needed. In fact she is very kind. She is very smart and strong too. When she was 19 years old, she is one of the most strongest fighter in their organization. Her father was very proud of her. Until one day, her father had a good deal with another villain, Joker. Their deal is, Y/n will be married with joker son, Ace.(I only took that name on a card because I thought that will be a good name for Jokers son because his name is Joker) Y/n didn't agree with this deal, so she decided to run away from her home. She was looking for a job so when she finds a poster of a maid hiring, she took the opportunity. But she didn't know that her boss was the one and only Black Hat which was cruel, cold, evil, and a heartless demon. She decided to keep her villain and dark angel identity a secret from her new boss. What will happen if these two people will cross each other's lives.......... Will a kind dark angel and a cruel demon think each other as a friend, a enemy, or something more~........ Warning : ~ swearing ~ bad grammar
