Nadia is a kind-hearted and compassionate girl who lives with her sister in a nursing home. Nadia has been able to speak to spirits and use magic ever since she was young, but because she wants to spend her days living carefree and in peace, she covered up her power and never spoke of it to anyone. One day, Nadia finds out that the nursing home is experiencing financial difficulties, and decides - on her own - to take on a request from the royal family in order to resolve them. But in the middle of handling the request, she meets two mysterious and handsome young men named Lut and Zack, and they find out about Nadia's power. Even worse, they give her the shocking truth that she is actually "the reincarnation of the kingdom's founding queen"...?! And to think, all she wanted was to live a peaceful life!
