For those with patience and a little knowledge of the era it's set in, this drama is a gem that is sorely underrated. It's episode format is a little different from most dramas; they aired 30 min episodes 5 days a week for about 6 months. This format let the characters slowly age and grow in a more organic way. This compelling slice-of-life storyline isn't for everyone, especially those that need a shocking revelation every episode to keep their attention. That's not to say that there isn't excitement though, Heo Jun's life was packed full of danger, compassion, intrigue, war, and dedication. The fact that these are actual events just makes it all the more compelling. I found myself eagerly checking for new episodes almost every day. I am notoriously hard to please when it comes to rating dramas, especially historical dramas, but this one is one of my favorites. I gave it a 9, which is high praise that only a few other dramas have gotten from me.
