Viera is a hardworking noblewoman from a impoverished viscount family. She toils as a court mage in the Magic Bureau’s Technical Department, sending most of her earnings to support her ailing father and household. When her father falls ill and the family urgently demands she find a husband, Viera is forced to attend a social gathering. There, ignored by the other nobles and frustrated by her lack of connections, she drowns her disappointment in drink. In her intoxicated state, she impulsively proposes a contract marriage to a nearby handsome knight with striking blue-gray eyes and black hair. The knight, Lukash, surprisingly accepts her terms: they will divorce after one year, and he requires nothing from her.

The next morning, Viera discovers that her new husband is no ordinary knight. Lukash is the country’s most powerful divine beast knight, a legendary hero revered by all. What was supposed to be a convenient, temporary arrangement quickly shifts as Lukash makes it clear he has no intention of letting her go. He begins to dote on her with overwhelming affection, transforming Viera’s once-struggling life into one of luxury and protection. As she navigates her new married life, Viera must come to terms with her husband’s true identity, her growing feelings, and the complications that arise from being wed to the strongest warrior in the kingdom. The story follows their evolving relationship, blending fantasy elements with romance and the slow unraveling of the misunderstandings that sparked their union.
