This manga takes place in a historical setting where the fmc decides to marry the cursed 'monster' in the place of her beloved sister. The supposed 'cursed monster' is a vampire. While reading this, I initially thought it would be generic. The storyline isn't anything that's relatively new to the shoujosei genre BUT the author does a good job with keeping the reader's hooked with each chapter. Moreover, the art is one of the most beautiful manga art I have ever seen! It's one of a kind! The art matches the vibes of a historical vampire storyline. Every character is gorgeous and the maincharacters are likeable ! While so far, there isnt much depth to the characters, I'm sure the author will slowly reveal more details and facts as the story progresses.
