After spending a year on the run in the human realm, Crown Princess Jisoo was finally caught by a task force sent by her country's own military. Tracked down and forced to return to the world she came from, where the tension between Demon and Vampire nations was steadily rising, Jisoo begrudgingly resumed her position.

Casting off her memories of the human realm, Jisoo must adapt to another strange and new world as she, as per prior agreement, moves to marry Crown Prince Jin of the Northern Territory - a rival Vampire nation - in the last desperate attempt to stop the threat of war escalating between the two kingdoms.
