One day, as punishment for seducing the engaged Second Prince, Virginie is ordered to marry Richard, the "Grim Reaper Duke," a man rumored to bring certain death to any woman who becomes his wife. However, to protect his doted-upon Virginie, their father decides to offer Violetta as a substitute instead. With no way to escape the situation, Violetta steels her resolve and marries the "Grim Reaper Duke." But the Richard she meets turns out to be a true gentleman who protects Violetta whenever her life is in danger. Why is someone so gentle called the "Grim Reaper Duke"?!
