I watched this drama when it was released.It was one of the best I have watched. It is great in every aspect such as acting which is best,music-one of the best OST's I've heard is there then cast is superb and they are well suited for there roles.
I don't really understand how people can dislike this drama..it has great start which keeps you watching till the end and with a great ending as well. I think one who dislikes this drama may be addicted to some fantasy type of drama and are not used to this type of genre and story.
As I end I shd say that this is a must watch and if you have chosen this as your first kdrama then it your choice and keep on watching it till end.
Thank you✌
