Jiang Yunyi, the eldest daughter of the Jiang family, was abandoned in the countryside from a young age and saved the severely injured Ye Mo Han. The two made a promise to each other. Twenty years later, in search of a medical manuscript and Ye Mo Han, Jiang Yunyi marries into the Fu family on behalf of her stepsister. Unbeknownst to her, Fu Jingshen is actually Ye Mo Han, the eldest grandson of the Ye family, and Ye Mo Han is unaware that Jiang Yunyi is the 'Moonpie' he has been looking for all along.
