Su Jinyue, a five-star chef, transmigrates into the body of an overweight wife who has endured endless abuse and is forced to marry Xie Chenyuan, a man suffering from a serious leg injury. She abandons her predecessor's timid ways and uses her exceptional culinary skills to set up a market stall, fiercely fighting back against her exploitative birth family and repeatedly thwarting the schemes and provocations of Lin Wan'er, the county magistrate's daughter. The couple find warmth and support in each other, starting with a humble food stall and building the Jinyue Restaurant together, only to face repeated secret schemes by the merchant Zhou Fulai. Working together, they gather evidence and expose all the forces behind the plots. Meanwhile, Xie Chenyuan's true identity as the wrongfully accused Marquis Who Guards the North is revealed, and the couple join forces to clear the decades-old injustice. Once the turmoil has passed, they resign from their official positions and return to their hometown, where they run their restaurant, raise twins—a boy and a girl—and enjoy a peaceful, prosperous life surrounded by the warmth of home.
