A little girl who developed a high fever at the age of six was able to see things that others could not see. She never left her room after that. Until the family fell into decline. Her only relative, her brother, had no choice but to send her to a private school. From then on, Jianan, who did not understand the ways of the world, used her own way to get along with her classmates. However, angels, vampires, monsters, and Taoist priests kept appearing in this school, leaving Jianan at a loss as to what to do.
