I decided to watch this drama because of main male lead ,he is ultimate . I had seen all his historical based drama and in every drama he just nailed it.
Come to story .
As I written in title the story about to find the secrets of two mentioned sword because of this some people selfishly killed the innocent people and the male lead thinks that to save the innocent is his obligations. So when he was doing this many people come across in his each phase of life and in each phase of his life he lost his important person.
At the end secret reveal and it went under wrong hand but everything went fine at the last .
One thing disappoint me that the chemistry between the leads started at the end's few episodes . As I like love story so I wanted to see their scenes equally than other scenes.
