Natsume, whose job is to accompany customers to sleep, holds the dream of becoming a writer, and faces the upcoming life of three years alone. She is a lonely person, but she is not afraid of being alone, she enjoys it. She greets different customers and finds writing inspiration from their experiences. After work, she dips in ink and uses the simplest pen on the simplest rice paper to combine other people's stories with her own feelings and write a book for whom she doesn't know who she wants to write.
