This is a youth novel of the post-90s generation, which accumulates many memories of the era. One day those born in the 80s and 90s will all grow old, and no one may remember their youth or what their era was like. As people grow older, many details will become blurry. If they are not recorded, all these will become the dust and smoke of history with the death of a generation and can no longer be salvaged.
Purpose: Memoirs of the post-90s generation
