The Marriage of a Cold-Hearted Duke and a Disaster Lady

To treat his uncontrollable magic power, Duke Christopher proposes marriage to Lady Cecilia, the daughter of a noble family. Cecilia, who agrees under certain terms, enters into a marriage where she is expected to help him with his treatment. As they live together, they gradually come to understand each other. Though their relationship begins as a contract, the two slowly grow closer as they share time and experiences. As their bond deepens, Cecilia begins to question her own role—not just as a noble's daughter but as Christopher’s wife. She starts to fall for him, even though she fears she may one day lose her powers. Although troubled by these thoughts, she becomes determined to support her husband as a true partner. During this time, a war breaks out, and Christopher heads to the battlefield. There, his magic surges out of control. Just as he is on the verge of collapse, Cecilia, who has rushed to his side, helps suppress the magic, deepening the emotional bond between them. However, the defeated general's daughter sets her sights on Christopher, plotting to take him for herself and threatening Cecilia's place. Even so, Cecilia never loses heart. She receives magical aid and confronts Louise. After Louise’s retreat, Cecilia and Christopher reaffirm their connection. With the Empress granting them her blessing, the two begin a new chapter of their lives together.
