I liked it a lot. I like how the Duke came around to his emotions and how to convey them. His character makes a lot of progress. I also like how Areum stays solid through the whole story. She stays true to the Duke. There were some hiccups in the story though. In episode 10, the Duke says that if he mates with a human he becomes mortal. They clearly have a child in the end and he was still vampire. I'm a little confused but the story was good in all.
