This is my first fantasy drama that I really loved after "My love from another star". The story is superengaging & the characters played the role really well especially Lee Jong Suk. If you're looking for a fantasy rom-thriller drama, there's no better choice than this. This drama has blown my expectations & was far more than just good. This definately needs to get into your watchlist & trust me you won't regeret this.
Overall for me this is a MUST WATCH kdrama which has everything you need for in a fantasy genre.
