Read the synopsis and you will know why I add "Love in Time" (2015) as recommendation. I think the synopsis got similiar to this one after I watched this.
Both of these dramas focus on a male vampire who is cold and withdrawn due to their past. These dramas are both incredibly overacted and a bit cheesy, but still enjoyable if you are looking for a vampire story with eye-candy.
Both are about a guy who loses his first love and becomes a vampire. The difference is that in Love in Time, the main story takes place in modern times.
