Poor art student Eugene is humiliated, beaten, and told that talent means nothing without noble blood. When the ruthless Duke Arthur saves him in a storm, Eugene becomes dangerously obsessed with the powerful man who treats the world like his private kingdom. After entering Windsor Estate through his best friend Allen, Eugene is pulled into Arthur’s cruel rules, forbidden desire, and hidden past. Determined to prove his worth, he follows Arthur to Paris, where a corrupt art dealer traps him in a black-market auction. Arthur rescues him at a shocking price, but their romance threatens to destroy Allen and expose the duke’s greatest secret: Allen is not his real son. After Eugene risks his life to save Allen, Arthur finally breaks, loses their seven-day bet, and surrenders his empire—and his heart—to the commoner he once tried to push away.
