Vampire genre in K dramas is less compared to zombie genre which gets better with each drama and even rivals western zombie films & dramas lately, but sadly for vampire genre k dramas there are only few & I dropped the Blood k drama, including this drama I only liked three other vampire k dramas that I watched.
The story of this drama revolves mainly around protag also called Night Scholar/Vampire Hunter & the Antagonist called GWI sort of elder Vampire I think if compare to western Vampire stories etc.
So this is the last Vampire K drama that I enjoyed watching, Protag becomes a Vampire as the main antagonist mortally injures the Vampire hunter who turns the protag into a Vampire to kill GWI, In this story vampire hunter is not humans but rather vampires that tries to keep their humanity, story revolves mainly around protag & the antagonist they are the main pillars of the story, if the actors who portrayed these roles didn't do a great job this would have turned into a bad & very boring drama.
Don't expect modern level Vampire action, this follows the old vampire genre style, slow paced but don't drag the story atrociously like older k dramas that increase frustration levels to max & also test viewers common sense & patience.
I liked the Vampire actions in this drama they may look old now but when this aired this was one of the best Vampire K drama I watched till that time, don't think there is any new Vampire genre K drama after this drama.
Like I mentioned above drama is slow paced and takes it's time to introduce the characters, story world etc, there is a lot of talking between characters and skipping can cause losing some important information regarding story, you will see GWI talking a lot he will reveal some info regarding his past and the people he met his lover etc, I have watched this drama more than 2–3 times and currently rewatching again this time gave more attention to GWI conversation and his interactions with other characters including Night Scholar aka main protag, in some scene we feel GWI might have some kindness next scene he does some brutal killing despite being hated he doesn't want to turn second female lead who works for ML, even tells her becoming a vampire with a heart is not easy one can die or turn into a bloodthirsty vampire etc, SFL aka the queen she looks like Night scholars old lover she has her plans in one scene we might think she is planning something next scene we see her human side, I think almost every cast in the show did well, compared to older k dramas or even some new ones this story is interesting till end, there is a start and end, most k dramas gets a great start then start getting bad and by the end viewer might start hating the show.
This is one of the better Korean Vampire genre drama. The drama has some good music, but sadly they have not used the music well to make some scenes even better like the scene where Night scholar loses his black cloth, and he has to save FL in the morning, I think the production tried to reduce the budget or go with low budget, so everything in this drama depends on the performance of the actors, the best part of the show is performance of the cast.
