Instagram posts made me to watch this K-drama. I was very excited because they have the deadly combo of Lee dong wook and Kim bum. The initial episodes found boring for me. But later it became really interesting. The story is based on legends playing many fictional characters. If you're not interested in legends you can drop this. Apart from contemporary K-dramas you won't find typical cliche here. It is a perfect mixture of romance and bromance. And it's climax.. I don't know how I managed not to shed tears. Background score also did work well. Lee dong wook just hit the spot. I'm sure you will have a good time watching it, if you love fictional dramas!
