A little girl was hit by a gangster's car on the street and her brain was damaged. The gangster took the little girl home and raised her for seven years.
Because the little girl was dressed as a boy when she was hit by the boss, the boss has been dressing the little girl according to boy's standards for the past seven years, and has never doubted the little girl's life experience.
It wasn't until the little girl was seven years old that the boss suddenly discovered that the little boy he had raised by his side for seven years was actually a girl...
It turns out that the little girl is not crazy at all. She pretended to be stupid for seven years and pretended to be a man for seven years. All this was a conspiracy carefully planned by the mastermind behind the scenes.
Concept: It tells the story of a girl who was sent to a big boss to lurk for revenge when she was ten years old.
