Lin Hui and her husband, Zhou Jianmin, run a fast-food restaurant and have spent three years providing free group-buying services for their residential community. They sort orders for free, deliver goods to residents' doors, and make life easier for their neighbors. But when seafood arrives a little late, their neighbor Wang Li demands 5,000 yuan in compensation. In the community owners' chat group, Wang Li plays the victim, spreads rumors that the group-buying ingredients are spoiled, and stirs up public pressure. After three years of kindness are completely dismissed, Lin Hui is heartbroken. She disbands the group-buying chat, removes the store's pickup point, and permanently ends the service. Residents are suddenly forced to pay more for groceries and struggle with inconvenient pickups. Only after experiencing the consequences do they realize what they have lost and unite to condemn Wang Li.
