When college student Park Y/N is mysteriously transported to a royal kingdom, she awakens as the long-lost 9th princess, believed to have been in a coma for years. Surrounded by the luxurious palace, she is faced with a world she doesn't remember, and a family she doesn't fully recognize. Her best friends from college, Jaehee and Yana, are by her side, but they don't remember their past lives or the truth of how they all ended up in this new world.
Confused and desperate for answers, Y/N tries to piece together the fragments of her old life, but the more she questions, the more everyone seems to brush it off as the lingering effects of her coma. Meanwhile, the kingdom is on the brink of political unrest, and Y/N's awakening threatens to disrupt the arranged marriage between her powerful cousin, Jeon Jungkook, and her elder second cousin, Kim Hyeyoon-the kingdom's future queen.
As Y/N struggles to accept her role in this strange new world, she must navigate political intrigue, family secrets, and the growing realization that her awakening could change the course of history. But can she trust anyone in this world? Or is she just a pawn in a game she doesn't yet understand?
