The busybody neighbor next door repeatedly steals Su Qing's flower express deliveries and spreads rumors to smear her. With endless tolerance yielding no results, Su Qing uses cash-on-delivery to set up a counterattack strategy. The greedy neighbor consecutively signs for high-priced cash-on-delivery flower bouquets, stepping into trouble step by step. Surveillance footage, audio recordings, and homeowner group confrontations cause conflicts to erupt layer by layer. In this neighborhood game of chess, there is no extreme revenge, only demanding the justice that rightfully belongs to oneself. In the end, grudges are reconciled, and Su Qing rushes toward a new life, protecting her freedom to buy flowers and realizing that one does not need to yield blindly—daring to speak up for oneself is true freedom in life.
