He is the most ordinary security guard in Anju Community and a laid-off assistant to Meng Po in the Wangchuan cafeteria in the underworld. He is sent to the human world to perform a secret mission: to collect various flavors and upgrade the recipe of Meng Po soup. A security room cafeteria with a fragrant fragrance late at night has become a haven for healing. Until the top gourmet investor whose past was buried by his "sacrifice" information - his ex-wife Lin Wan, followed the familiar smell that made her soul tremble. She thought the reunion was to make up for regrets, but the closeness in his eyes was to collect "the taste of broken love". When the community cafeteria becomes the intersection of the yin and yang rift, and the evil ghost uses his obsession with food to escape from the world, he has to hold the spoon in hand and face the surging strangeness. And she chose to stand beside him, using the fireworks of the world as firewood, and the unfinished love as a guide, to cook a "five-flavor soup" with him that could calm the yin and yang and calm the ghosts and gods.
