As the descendant of the hidden cooking god, Shen Nianxin works as a teacher and cook in her small kindergarten, living a peaceful and warm life. Until a mixed-race boy named Huo Xiaobao came to the garden, who was as delicate as a porcelain doll but scorned any food. When he went on another hunger strike to protest, Shen Nianxin brought out a bowl of home-cooked scallion noodles drizzled with sesame oil. The little boy was stunned, and then cried out "Wow". A pair of small black horns popped out of his head, and his tail wrapped around her wrist. His milky voice was choked with sobs: "Sister Niannian, I have been looking for your smell for three hundred years." Only then did Shen Nianxin remember the "Little Hei" who followed her eagerly in the mountains in her childhood and then disappeared inexplicably. Now, her kindergarten hides her childhood sweetheart, an ancient ferocious beast, a picky glutton cub, and various little monsters disguised as human cubs that are attracted by the aroma of the food one after another. The arrival of the Demon Realm Management Bureau and the mysterious hunter suddenly made her kindergarten cafeteria the focus of the three realms.
