Unlike her beautiful and magically gifted younger sister, Elma was ordinary and incompetent. She had been shunned by her father and sister, and was bullied constantly. One day, she met a man whose face was hidden by a cloth. He was a knight, known as a “demon” who could take away the sanity of anyone who saw his face. Elma inadvertently saw his true face, but she wasn’t fooled. A man who was interested in her came to see her for no reason, and when he learned that she was unhappy, he forcibly took her out of the house.
At first, Elma was confused, but then she was drawn to his kindness. Meanwhile, while living happily in a safe place, Elma gradually regained her sealed memories. It seemed that the family that bullied her had some secrets of their own. This is a super royal Cinderella love story in which a daughter who was unjustly oppressed becomes happy after being discovered by a beautiful ducal knight.
