Ottilie, the daughter of a Marquess, possesses the ability of "Mind Reading." Because of this, she has been oppressed since childhood by her older sister, Iama, who wields the magical power of "Charm."

One day, through a twist of fate, Ottilie ends up attending a ball at the Royal Palace. While the people around her treat her with fear and disgust for her ability, the inner voice of Crown Prince Varic reaches her:

For the first time in her life, Ottilie meets someone who affirms her existence. She is soon appointed as the Crown Prince’s Aide.

However, Varic starts approaching her not as a superior, but with overwhelming sweetness and affection...!?

Meanwhile, jealous of Ottilie's newfound success, Iama begins to plot in the shadows to drag her sister down to ruin...
