This story is about an obsessive love and a man, slowly drifting into insanity because of this twisted love, because of his twisted soul and there is a very artistic expression about it. An absorbing, artistic story. Absolutely successful acting with very good looking actors and actresses. Extraordinary, unforgettable music and OSTs. The music is great and very relatable to the story with the lyrics. Many times I've heard people complain about k-dramas' music and say that even if they were going to watch it, they wouldn't be able to watch it because the music was too cringy. Well, if they had seen this show, I'm pretty sure they would never have complained about it.
