When Miyo finally comes of marriageable age, though, her hopes of being whisked away to a better life crumble after she discovers her fiancé’s identity: Kiyoka Kudou, a commander apparently so cold and cruel that his previous would-be brides all fled within three days of their engagements. With no home to return to, Miyo resigns herself to her fate-and soon finds that her pale and beautiful husband-to-be is anything but the monster she expected. As they slowly open their hearts to each other, both realize the other may be their chance at finding true love and happiness.“
