Five Heavenly Babies, Daddy Get Ready！

The obese and insecure Xing Yunshu is tricked by her sister Xing Yike into drugging her husband, Gu Linyuan, for consummating their marriage. Accidentally, she breaks his legs and is banished to her rural hometown. In despair, the soul of an ancient divine physician transmigrates and possesses her body. After losing weight and achieving a remarkable transformation, she supports herself in the countryside using her medical skills and gives birth to quintuplets (Monday to Friday). Five years later, the adorable children encounter their biological father, Gu Linyuan, and are taken to his home under the false pretense of being abducted. To conceal her identity, Xing Yunshu works as a cleaner in the Gu family home under the alias "Yunshu," secretly protecting the children. Gu Linyuan gradually develops feelings for the children and "Yunshu," but he keeps discovering flaws in Xing Yunshu's identity. Xing Yike's repeated attempts to frame her ironically only strengthen the bond between Gu Linyuan and Xing Yunshu. Ultimately, with the children's help and a series of crises, Xing Yunshu reveals her true identity, and the couple reconciles. Gu Linyuan accepted the child, Xing Yunshu promised to heal his leg, and the family of seven was reunited.
