Hakuchuumu no Aojashin

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.
