Not gonna lie, the main reason I watched the show was for Kyung Soo and So Hee, however, it was a fun, charming, and gracious ride.

I've watched a couple of dramas that had this historical plot somehow, but never one that was fully committed to it. I ended up enjoying it a lot, it was nice to see a representation of the old (but really old) days, even though I know it's impossible to get a 100% accurate portrayal of it.

Story: I enjoyed the main story and the first half of the side plot, but after a while, the second narrative going on became a little repetitive and confusing.
Acting: Amazing cast, all the emotions were portraited perfectly for each character.
Music: The mixture of old new sounds was a perfect addition to the show, it has a great OST.
Rewatch Value: I will watch it again, perhaps paying more attention this time to the second narrative than to the main story I may be able to understand why everything became so weird at some point.
Overall: Recommended for those who like classical stories dramas, but don't expect a lot of romance or fighting, it has both, but not in excess.
