Underworld Complaints: Acquaintances First

Funeral after-sales specialist Jiang Zhao is poached by the Underworld to join the hotline department with a base salary of 28,000 yuan. On his first day, the vengeful former client Zhang Jiaguan complains about a paper villa missing a toilet. After investigating the logistics error and soothing the ghost's anger, Jiang Zhao discovers that 392 of his earthly clients are actually restless souls from the Underworld. He successfully resolves multiple group incidents and is exceptionally appointed as the Yin-Yang after-sales specialist. However, mysterious ownerless ghosts frequently appear, leaving notes that reveal hidden system loopholes within the Underworld.
