I find historical cdramas often hard to follow. This show is clear and you can skip through without being lost. I love the relationship between the two the MLds, without the interference of a female character. There is a underlining question that keeps you on the tip of the toes. Trying to follow the clues to find the right answer. There are a few filler episodes you can skip through, and it doesn't hurt your understanding of the series. overall this show is easy to follow with interesting plot points along the way.
