Liu Qian is a property manager in an ordinary residential area who provided value-added services to the residents for free for three years, including watching children, walking dogs, sunning quilts, and more. She served the property owners diligently and conscientiously, but because an elevator repair delayed her in picking up a child by three minutes, she suffered malicious reports from the owners. Liu Qian woke up to reality and decided to close her doors and stop serving the residents of the residential area. The next day, the residential area fell into complete chaos.
