First of all, Lee Joongi is one of my favourite Actors (along Song Joongki), but I am not a fan of all of his dramas. One Drama I dropped because in my opinion the role in 'Hero' didn't suit him. I planned to see SWWTN even before he was confirmed as the male lead. But when I read that he would play the role of Kim Sungyeol I was happy because I missed him in a drama. The Story sounds interesting (I didn't read the manhwa) so I was excited for the beginning of July when the drama started. Normally I don't like dramas with Vampires but I thought that it would be different, if it is set in the Joseon period. So I started the drama from beginning when it was aired. The Beginning of the drama was very interesting, but some scenes was a bit...not boring for me, but not so, that I would give it a 10. The Cast was very good. Lee Joonki plays his role as a Vampire scholar very autenthic and even though I wasn't a fan of him after this drama I would be one. Before this drama I thought already that he is the best when it comes to historical dramas, even though I would love to see him in a drama like 'Two Weeks' again. When I heart that Lee Yoobi would play the female Lead I was sceptical. I watched Pinocchio and there I found her very annoying. But I think she did very well and the Chemistry was very good. Kim Soeun is a very talented actress, but her role was a little bit confusing. Changmin surprised me with his role as the crown Prince. He acted very well compared to his drama 'Paradise Ranch'. Jang Heejin and Choi Taehwan did their rifht thing and were well, too. But what I like the most of this drama is the Music. I love the OST. All of them. In my opinion it is the best OST in a drama this year. All in all I would recommend the drama and I will watch it again, if my 'plan to watch'-List is smaller^^.
