I find the storyline of an innocent love story of two strong leads fighting for the unification of 3 countries meaningful. And, the replacement male lead and the female lead had really great onscreen chemistry and their acting is superb. However, as the episodes built up, there were so many different villain characters being brought in, each with their personal and evil agenda which made it went a bit off as the story should focus more on the relationship between the lead couple and how they bring about the unification of the 3 countries. So, there did not need to have so many villain characters but just a few main villain characters will do. Nevertheless, this drama was good and touching.
