Su Qing, a modern graduate student, accidentally traveled through time. As soon as she fell into a designed "catch an adulterer" incident, she was fully protected by her reborn mother-in-law, Wang Cuifen. Wang Cuifen was abandoned by her biological children in her previous life, leaving Su Qing to take care of her until she died. In this life, she only doted on her daughter-in-law. The mother-in-law and daughter-in-law teamed up to tear down the best of the Su family and punish the unfilial children of the Xie family. Su Qing also helped her husband Xie Jianhua avoid the fate of sacrifice, and the relationship between the two warmed up. With the support of her mother-in-law, she prepared for the college entrance examination and was admitted to Beijing University. The mother-in-law, daughter-in-law, and husband worked together to get rich, and finally got rid of the bad relatives, and the family of three lived a prosperous and happy life.
