Asato

Chloe thinks she's an outcast because she does not get along with her stepmother or her fiancé, Emile. One night, she goes to a masquerade ball, where she witnesses her stepsister, Beatrice, and her fiancé, Emile, kissing each other! Heartbroken, she is biting back her tears when a mysterious man with a mask appears, hands her a handkerchief, and leaves. Chloe is confused, but this strange encounter is soon forgotten because she is forced to call off her engagement with Emile so that he can marry Beatrice. That is when Chloe receives a marriage proposal from a man known as "the Devil of Blysche"...!

Natalia, a Count's daughter, can't bear the thought of marriage. The reason is that she can see people's emotions as colors of their aura. Her maids, while smiling, seethe red with hatred, and her gentle teachers bristle with the color of anger. Unable to trust others, Natalia botches her debutante ball and becomes a recluse. Concerned for Natalia, her younger brother Julian drags her to a ball hosted by a member of the royal family. But the overpowering mix of colors and auras makes Natalia feel sick. Suddenly, an aura flaring with red anger and black hatred appears! She's never seen an aura so dense that it completely obscures the person emitting it. Natalia freezes, trembling as the figure approaches her. But as he draws nearer, she recognizes him as His Highness, Prince Ludwig...?!
