In this chapter, a young man named Shuguang recounts the story of how he came to live in his parents' apartment in the city of Changchun in China in the year of 2014. After graduating from university, Shuguang's parents bought him an apartment on the top floor of a building in the spring garden of the building. Shuguang had been working as a voice control light in the corridor of the apartment, but one day, he suddenly saw a shadow enter the stairway. He hid in the room and watched as the shadow moved through the narrow air vent. When Shuguang realized that the shadow was a man, he began to wonder why he was being watched. When he realized that it was two people, he decided that it must have been a fight. When his neighbor, yani, saw the shadow, she also felt the same strange feeling as Shuguang. When she realized that her eyes were staring at her, she began to cry. .
