This article is probably a sadistic one. It tells the story of a heroine who travels into a book she wrote and uses a street order to kill the hero who goes to the river to save her but is pulled into the world of the book by her.

A life that has experienced two important life stages: the war between immortals and demons and the rupture of the book world.
