Blue glass, a transparent blue ceiling, blue leaves, and power poles skim the top of the train car, while the teenager leaning on the seat quietly observes the scenery overhead. The carriage is exceptionally quiet, with no other passengers besides him.
The train clanks gently forward, and beneath the twilight sky, everything seems to be coated with a faint layer of blue. When passing through intermediate stations, mechanical announcements briefly break the silence of the carriage.
[The train has now arrived at Suoqing Station. Passengers disembarking at this stop, please exit in an orderly manner.]
The train doors slide open slowly, but nobody gets off. The station is empty, with only a few indistinct birds perched on the power poles, uttering several cries.
