After dying on the battlefield, a knight awakens in a new body—inside enemy territory, in the domain of the grand duke who was once her greatest rival. To her surprise, he recognizes the woman whose body she now inhabits and seems to have cared for her deeply. Determined to use this second chance, she becomes his personal butler while secretly planning to earn his trust and eventually return home with his head. Two years later, however, she is still by his side—and receiving far more love and devotion from him than she ever expected.
