Fate sure likes to keep Cecilia on her toes. After being reincarnated as a doomed villainess in an otome game, she was sent to work in the brothels only to be saved by Lucas, the captain of the knights and second-in-line to the throne. But duty calls when an ancient dragon appears and Lucas--the kingdom's hero and sole wielder of the legendary sword Eckesachs--is called to save their kingdom from calamity. To make matters worse, Cecilia learns that every hero who has faced an ancient dragon in the past has been slain! Nevertheless, Lucas departs for battle with a promise that they will wed upon his return. But does fate intend to send him to the altar...or the grave?
