Rural woman Hu Xiaotang, along with her daughter Momo, returned to the city with her educated-youth husband He Wenhao, only to face all sorts of disdain from the He family. Externally, the He family only claimed she was a nanny, refusing to register their marriage, and the cowardly He Wenhao also followed his family in mistreating the mother and daughter, with Momo even being called a wild child. After a conflict, Momo was accidentally injured, and Hu Xiaotang, with no money for medical treatment, fell into desperation. She unexpectedly met Guan Tingshan, a steel mill hero who was disabled in the line of duty and wheelchair-bound. Guan Tingshan admired her resilience, proposed marriage, and promised to give the mother and daughter a stable life and city household registration. The two registered their marriage to form a family, and Guan Tingshan sincerely treated Momo, helping her enroll in a key primary school. The He family grew jealous and repeatedly spread rumors to make things difficult.
