All of humanity has come to share the same dreams.

Some nights, a tale of adultery between a teacher and his student.

Other nights, a romance between a commoner playwright and a noblewoman actress.

Yet other nights, a story of burgeoning love between a truant young man and a teacher-in-training.

Again and again people see these same three dreams.

Why does everyone now endlessly experience these dreams?

This is the story of the girl who's called the world.
