An ordinary schoolgirl with an idealistic dream longs for a fairy tale romance and her own “prince charming.” But her world changes the moment she discovers a mysterious book hidden in her school library. When she opens it, she unknowingly releases the sealed characters of Grimm fairy tales into reality.

Suddenly, her everyday life is overtaken by strange encounters: enigmatic hunters, dangerous wolf-like figures, and other unsettling beings drawn from stories she thought she understood. Each carries their own motives, and not all of them are safe. As An is pulled deeper into this fractured fairy tale world, the line between story and reality collapses, and the idea of romance becomes something far more dangerous.
