「'For a woman, you're far too meddlesome. Therefore, I'm calling off our engagement!'」

Histrica, the only daughter of the Viscount Erland family, known by derogatory nicknames like "The Ice Lady" and "The Emotionless Iron Mask," not only had her engagement broken off by her fiancé with those words, but also learned that her fiancé had been stolen by her best friend from their aristocratic school days.

Severely branded as "damaged goods" at a social ball, Histrica, convinced no one would ever marry her now, was about to put a definitive end to her life as a noble lady. However, her destiny took a drastic turn after she helped a man who seemed unwell.

She ends up getting engaged to Erik, who is whispered to be "The Hideous Duke" in society.

Erik was once hailed as the royal court's genius prime minister, but he suffered from an illness that left him with a gaunt appearance.

However, Histrica, who had undergone a Spartan education since childhood and possessed more knowledge than a dictionary, had a lead regarding Erik's illness...

This is a story about a brilliant, mentally strong, but slightly eccentric girl who, while bringing a workaholic, emotionally broken duke back to a more human life, rediscovers her own emotions, gets her revenge, and finds happiness.
