Fan Ci is an inconspicuous little cook in the imperial kitchen. On the surface, he is docile and has a shy smile, but in fact, he is paranoid and sinister in his heart, with an almost pathological possessiveness towards the people he recognizes. After accidentally saving the prince who left the palace incognito, he was promoted to be the private chef of the East Palace. From then on, he used delicious food as a blade and gentleness as a net to make his way in the deep palace. While curing the prince's anxiety and loneliness with exquisite snacks, he quietly eradicated all those who coveted the prince. But the powerful and ambitious regent became his most dangerous opponent - the only person who could see through his true face.
