The Grim Reaper and the Young Lady

Yulia is the beautiful daughter of the Duke Anker, but she has the reputation of being a haughty and cold-hearted "villainess," which caused the Fourth Prince to break off their engagement. Instead, she gets married to the widowed Marquis Winkler, a man with the fearsome nickname of "The Grim Reaper."
