To raise medical expenses for her grandmother, Jiang Li incurs high-interest debt and is forced to take on pet correction work for the Sheng family. Sheng family eldest daughter Nan Yin suffers from severe depression, and the nourishing soup sent by her stepmother feels bizarre; her fiancé, who should have protected her, heartlessly breaks off their engagement at this moment, and layer upon layer of mysteries follow one after another. Facing two furry children driven mad, Jiang Li strongly breaks the deadlock with a bowl of extra-stinky snail rice noodles. Under the undercurrents of the rich family's internal strife, that eldest uncle who seems to be merely caring for Nan Yin is always watching everything at critical moments—what exactly is he plotting? Healing and comedy intertwine, can Jiang Li lead Nan Yin out of the haze, letting lives that fell into the long night ultimately see the fog clear and the world?
