Su Wanqing, the heir to private cuisine who has lost his sense of taste, is forced to cooperate with Gu Yan, an international gourmet who broke up three years ago in order to save the old restaurant that is on the verge of demolition.

In the old kitchen full of fireworks, they must jointly recreate the taste in their memories, and taste each other again in the bitterness and sweetness - can the ingredient called "regret" be slowly simmered into a bowl of perfection worth waiting for?
