A certain continent, a certain era. The war between the north and the south of the mainland is over, and the world is moving towards peace. Violet Eve Garden, a soldier in the war, left the army and came to the big port city with the "words" left by people who were very important to her. The enthusiastic crowd shuttled to and fro on the streets lined with gas lights. Violet found a job as a "letter writer" on the street. It is the work of organizing the corresponding language according to the client's idea. She faced her clients and touched their innermost frank feelings. At the same time, Violet came to understand the meaning of the "words" as she recorded the letters.
