The story takes place at the beginning of the 19th century. Goo Hae-Ryung is a historian who tries to fight gender stereotypes as her work is often looked down on. She meets Prince Yi Rim.
This is one of the best examples I've came across to what I like to call a "cosplay show", it had little to no serious consideration for its proposed era. The trend continued when the drama started to get preachy from a modern society point of view while being in no position to allow it to attempt such a thing. These could have been avoided if the drama was a parody, of which, it was not. There were obvious other problems and inconsistencies too, but what stood out the most was the mundane sequences filling the biggest portion of the drama, these were a real brain rot.
What did the drama want to be? A social commentary, a political play, a profession spotlight, a slice of life, or a light romcom? It never embraced any aspect of fully committed to a theme. Whenever it tried to delve deeper, it pulled itself back up to the surface. Unsuccessful mix, regardless. There were other points to be made about the cast, chemistry, and romance but I don't feel like repeating myself.
