In this era of hypoxia, there is a remote and mysterious northern grassland town (time and space swap). The ancient capital of Beijing is already flashing with neon lights. A delicate girl is sitting in a cafe and drinking her last sip of coffee. At this time, her symbol is an older female from Beijing. No one remembers her name, and no one knows her story.
Suddenly a panicked customer burst in and accidentally broke the coffee cup. The fragments scattered on the floor, as if tearing the girl's entire dream to pieces.
If one day you become that person who rushes into the Beijing subway station and rushes to work during the morning rush hour, your youth has been lost.
