Lin Xiaoman accidentally discovered that the customers he delivered seemed to have secrets.

Lin Xiaoman's curiosity was completely aroused, and he began to use his identity as a "food delivery" to piece together bizarre stories like a detective through takeout orders, customers' words and deeds, and even the residue in the trash can.
