Lin Xiaoyang, a delivery guy with a "detail-obsessed" habit and deduction addiction honed from his job, always helps neighbors with small troubles—until he stumbles into a murder scene investigated by criminal police Su Xiaoning. He reconstructs the crime using a takeout slip and shoe prints at the victim's door, but is detained by Su as a "suspect." From bickering to partnering, Lin solves serial express thefts and influencer domestic violence cases with his "delivery guy perspective," even uncovering clues about his sister missing for three years. Su gradually discovers this yellow-jacketed boy not only has a photographic memory but also secretly took a knife for her. When the truth comes out, the "busybody" she once despised has long become her most reliable "civilian Sherlock"—even her heartbeat signals their growing bond.
