Introduction: Su Wan, a social genius who is only good at caramel pudding, hired the reclusive Michelin chef Lu Yan in order to cover up his culinary skills. Their relationship began with a sweet deal: lifelong pudding in exchange for the lifelong mask of 'Boss Su'. Faced with professional doubts, how does Su Wan use high emotional intelligence in public relations? When the trauma recurs, how to appease his "fear of fire" with pudding? Former colleague Mr. M investigates the background, how to protect each other's secrets? In the smoke of the kitchen, the deal gradually turns sour, from partnership to redemption. Lu Yan: "What will you do if my identity is exposed?" (Low voice) Su Wan: "Then we face it together, at worst, I will make pudding for you for the rest of our lives." (Steady eyes) However, when Lu Yan confessed the truth about the fire three years ago, a bigger crisis also came: the real reason why he chose to live in seclusion was far more painful than she imagined.
