The restaurant that Sonmi~451 lives and works in seems to be the very same café that Vyvyan Ayrs dreamed about before composing his best work. This illustrates how, in addition to the book’s nested structure, where each chapter is a story inside the next chapter’s story, the stories have other, less linear connections to each other. The futuristic terminology and character names in the chapter make it clear that this story contains elements of science fiction. Sonmi’s number, “451,” is likely a tribute to Ray Bradbury’s famous science fiction novel,
Fahrenheit 451.
