The little girl Meng Jingran was abused by her parents, who valued boys over girls and treated her like a servant.
The abuse since childhood made the little girl understand the ugliness of people, and she decided that she would take revenge on those who bullied her.
The little girl can see ghosts, and she kindly reminds the children and parents. But everyone didn't believe her and regarded her as a madman, insulted her and beat her. Aunt Wang from the house next door didn't like her and flushed her with water.
All this made the 5-year-old girl feel twisted. She vowed to make Sister Ghost well fed and let Aunt Wang and her parents go to hell.
Ten years later, she met Yuan Yi again, her brother when she was a child, and the seeds of love sprouted with him.
