Aiko Satō, who has won many literary awards, retired from her life as a writer and had no guests. She spent a gloomy time, but then a middle-aged editor named Tachibana came with a commission for a story. The story begins with a series of essays that are initially unpleasant, writing out her anger towards society. Aiko's life will undergo significant changes by the time she is 90 years old.
