The protagonist, Tanaka Jueru, enrols in a distant school with the certainty of not finding any of her middle school classmates. However, her class is full of well-to-do and socially integrated boys, while she is unable to make friends with anyone.

During recess she sits on a chair in the corner of the classroom to pretend to be asleep. One day she has a lucid dream, and from then on she always comes up with new tricks to make more of them, choosing to have fun in her dreams rather than interact with her classmates in the real world.
