Having watched most saeguks ( historical kdramas ) out there , i didn't expect much from this drama but i still started it for a pretty shamefull reason : Lee soo Hyuk and Lee Jun Ki . If you guys start watching this , just do not judge it based on the first episode because it doesnt get entertaining until the second one . So now i will state my honest opinion on this drama . First , Lee jun ki is known for his saeguks , that is why he is playing his role perfectly . Lee soo hyuk is also doing really well , his character actually suits his the best . He actually does look like a vampire lol !! Moving on to Chang Min , that guy suprised me . For an idol , he is doing amazing and looks so hot with his beard xp . The main actress , lee yoo bi , is so refreshing . I watched all of her dramas , it's her first main role and she is doing just great . Her chemistery with lee jun ki is also fantastic . On this i'm saying Bravo !! Let's move to the thing i disliked : Kim so eun . Don't get me wrong , i really like this actress. But her character is meaningless ( i mean the double of his first love ) . I really hope she has some kind of impact in the next episodes . Second , the storyline is pretty good , not outstanding either . I know its an adaptation of a manhwa , but there are some things which dont make sense sometimes and illogical stuff but it's still great . The loveline is well managed and not too cheesy and is different than typical drama lovelines . The vampire side might not be that attractive , for me at least , but it is not a twilight thing so don't worry . Finally , if all this reasons were not enough , well watch it for Lee Jun Ki's beautiful eyes at least ( seriously he is stunning ) !! Hope i was of some kind of help :D
