Mira, a pure-blooded human, is sent to the Dracula family as a peaceful hostage, becoming the adopted daughter of the Duke and Duchess and a princess of the vampire kingdom. She possesses the ability to read minds, seeing through the cold exterior of the heir, Dorian, that he deeply loves her, and also befriends the loyal Nova. At the academy, Mira is harassed by Iris, but Dorian protects her at every turn; at a banquet, she is provoked, and Nova stands up for her. During a camping trip, Mira is severely injured by the pro-war faction led by Leo and Iris. On the verge of death, Dorian uses his Embrace to transform her into a vampire, forging an eternal bond between them. The conspiracy is thwarted, peace is maintained, and Mira grows from a helpless human into a cherished vampire princess, living happily ever after with Dorian, achieving a perfect ending.
