Apartment resident Shen Feng kindly gives neighbors rides to commute, using it only to split gas and toll expenses. Newcomer Qiao Wei floats the idea of free commuting, causing neighbors to abandon their original carpool. However, lacking standardized free service proves unsustainable, with frequent issues such as missed schedules and missing service causing deep distress to the neighbors. Everyone finally understands that human favor cannot override rules. Shen Feng lets go of moral kidnapping, joins several car owners to build an open and transparent mutual aid carpool model, and returns neighborhood travel to a rational and orderly state.
