Pregnant Lin Wanning always thought the nanny was hired by her in-laws, until a call from her mother revealed that Sister Wu's 6,500-yuan monthly salary had always been paid by her natal family. Although the service object was clearly herself, her mother-in-law routinely arranged for her to take care of her sister-in-law, who was also pregnant. Not only did her husband Gu Mingchuan know about it, but he also helped change her service, arrange prenatal checkups, and postpartum care. After being repeatedly ignored, her husband still chose his sister on the night of delivery. Lin Wanning completely gave up, left the Gu family with her child, filed for divorce, and took back control of her life.
