At her daughter Siyan's seventh birthday party, the protagonist Lin Wan discovered that her mother-in-law had added her nephew Zhou Ze's name to her daughter's birthday cake without authorization, and forced her daughter to give up her beloved cake doll to her nephew. That night, her mother-in-law and her husband Zhou Zhiyuan tried to persuade Lin Wan to give up the school district housing she purchased with her pre-marital property to her nephew, a boy, but Lin Wan refused. Later, Lin Wan discovered that her mother-in-law had already used a forged power of attorney and stolen documents to illegally transfer her daughter's degree to Zhou Ze. After her husband learned about it, he still asked her to compromise for the sake of the family interests. Lin Wan was determined to fight back. She first reported the loss of her real estate certificate, invalidating the certificate in her mother-in-law's hand.
