The Witch of Paitan Manhwa

Margaret marries Carlos, the feared Grand Duke of the northern Duchy of Paitan, whose grim reputation has earned him names like the Wolf of Paitan and the Incarnation of the Devil. Though he once vowed never to marry her, he changes his mind, and Margaret takes their marriage as fate. His cold behavior on their wedding night—and his later interest in her maid—does little to trouble her, since she plans to leave quietly soon. When Carlos begins to approach her more intimately, Margaret remains convinced that their bond is not meant to last. But he insists they cannot part until one or both of them die. After Margaret learns the secret he has kept, she understands that their connection is bound by a long-standing fate, and that their marriage has been destined to end in death from the beginning.
