Xiaolin's private EV charging station is repeatedly used without permission by Auntie Wang, who lives upstairs, and her son, Wang Bao. When Xiaolin asks them to stop, they accuse Xiaolin of being stingy. Xiaolin remotely locks the charger, installs surveillance cameras, and leaves town. Auntie Wang secretly hires someone to dismantle the charging station and illegally connects the wiring. Their unauthorized use of electricity causes a fire that destroys neighbor Brother Long's Rolls-Royce. Auntie Wang tries to shift the blame onto Xiaolin, but Xiaolin presents the surveillance footage and exposes the truth. The court holds Auntie Wang fully responsible and orders her to pay 680,000 yuan in damages. In the end, her house is auctioned off, her son flees, and she falls into poverty and mental instability. Xiaolin eventually sells the apartment and moves away, realizing that kindness must have boundaries and that there is no need to tolerate greedy and selfish people.
