Lu Zhiwei, the heir to a century-old catering family, completely lost his sense of taste after an accident. The family's time-honored brand "Lu Yuan" is in danger. In a desperate situation, she signed a contract with Gu Shi, the son of her "enemy" who was terminally ill and had an extraordinary sense of taste. He became her "tongue" and she helped him recreate the taste deep in her memory. A contract bound the fate of the two people in the smoke of the kitchen. From mutual use to mutual dependence, they boiled their emotions in the interweaving of ups and downs, and also faced inheritance crises and business plots together. When the contract expired and Gu Shi, who was in critical condition, quietly left the scene, Lu Zhiwei suddenly realized that what she had regained was not only the sense of taste, but also the deep affection that had been integrated into every dish and was based on life.
