One of the best dramas in 2013. The cast is outstanding, it's very exciting because of the scary elements and the love-line is very adorable! This is a must watch, with eye candies (So Ji Sub, Seo In Guk OMG), with 10/10 music, twists, and it hardly contained super annoying characters who you want to punch in the face! I have watched so many dramas which had a really strong beginning but all went to disappointment. Not this one! It won't dissapoint you until the very end :)
