The ending reveals that all the previous stories were actually created by a single writer.The writer included his own story in the book, including the murder of his wife.However, an astute reader discovered the lie and exposed the writer's true identity.The writer suffered a nervous breakdown and was sent to a mental hospital.
Although the writer firmly believes that there are ghosts in the world, this belief may be just his own fantasy.In the last scene, the appearance of the female ghost can be understood as the writer's fantasy, and his repeated words of "there are ghosts in the world" may be that he is hypnotizing himself.This ending not only satisfies the regulations of the State Administration of Radio, Film and Television, but also paves the way for the broadcast of the third season of "Soul Ferry".
