I had my doubts when I read the premise - a man in a woman's body sounded odd. However, I'm so glad I watched this!
Most dramas let go of their comic sequences once they get to the more serious plot points - this drama kept cracking me up throughout. I didn't want it to end!
The acting is brilliant - Mr Queen & King Cheol Jong, alongwith the supporting cast - fit so aptly in their role. I loved seeing how they embodied all the different emotions of their character, alongside a healthy dose of humour. The ML surprised me the most - I didn't expect to like him as much. His reactions to the queen's antics are phenomenally done!

I can see myself coming back to this drama, time and again, whenever I need to lift my spirits.

--spoiler ahead--
I have to say: I severely missed bong hwan in the ending - I wished that he would return to the king but he didn't. "The thought of both Bong-hwan and Cheol-jong going through life with a gaping whole in their hearts longing for something they will never have again just kills me." - this feels extremely unfair to cheol jong & bong hwan. Even though they're played by the same actress, I wanted bong hwan to continue in joseon rather than so yong.
