It's a decent drama but a few things held it back. Inconsistent pacing was too obvious to ignore. The inconsistency carries on with the writing, sometimes they are strategic and smart while other times they throw themselves as a human shield, this is coming from the same army and the same leadership. I liked the leading cast they did a good job but I wish they put more effort into writing the character Yi Hyun. While the romance is a side thing, they could have given it more attention to let it mature and develop more appropriately or remove the romance altogether. Their encounters were scarce which made the high moments less impactful due to the lack of investment in their relationship. Anyway, the drama is one of the better historical ones.
