Physician Lin Wanqiu accidentally takes her elder sister's place in an arranged marriage and marries Shen Yanbei, the seemingly ordinary butcher from the eastern end of the village. Expecting a life of hardship, she is surprised to discover that her husband not only dotes on her but also secretly owns three properties in the provincial capital, hidden beneath his pillow. With her exceptional medical skills and talent for managing accounts, and with her in-laws' wholehearted support, Wanqiu resolves misunderstandings and builds a thriving grocery business from scratch in the county town. Along the way, she unexpectedly reunites with her biological family, from whom she was separated many years ago. Finally, surrounded by her family's love and protected by her devoted husband, Wanqiu moves forward hand in hand with him toward a warm and happy wedding.
