Historical and/or political drama are not necessarily my cup of tea, so I usually avoid these genres. I started watching this drama solely because of its popularity, a recent show, a romcom genre, and the ending. I surprised myself I binge-watched it in 3 days!

Like:
- Eye-catching front cover (see my comment on costume below)
- Straigth-forward story line, no plot twist, no shocking surprises, no betrayal. Secrets here and there revealed little by little like pieces of puzzles.
- Not dragging, no filler scenes or conversation.
- Perfect casting, every actor/actress fit their roles well.
- Great chemistry between ML and FL
- Some reviews/commentsI read about actress Shin Se Kyung, that she was bland or stiff in her role as FL. IMO she nailed it perfectly. Hae Ryung role is non-chalant and no-nonsense, which distinguished her with from most women in the drama Joseon Era. We can see her character intro in the beginning when she prefers to read a thriller novel to a group of women who prefer to hear romance instead.
- Some reviews/comments I read about actor Cha Eun Woo's bad acting skills especially in the beginning of the drama. IMO Prince Rim is supposed to be socially inept being confined all his life and only communicates with his subordinates whom have been with him for a long time. There should be a character growth for Prince Rim once he is introduced to outside world thru Hau Ryung, other historians, the French guy, the epidemic area, and Seoraewoon. and how the plot develops. Cha Eun Woo did an outstanding job acting the character transition. I actually cried when Prince Rim broke his heart due to the King's banning him writing romance novels and confiscated his writing tools.
- No love triangle (although there are potentials), so no Second Lead Syndrome
- Amazing friendship and family relationships, and loyalty.
- Happy ending for OTP and most other roles. No death.
- At some point of the drama, some roles become ambiguous , you will be uncertain if they are protagonist or antagonist. The ambiguity adds the spice.
- Beautiful cinematography
- Brilliant costume: I like they chose pastel colored costume for the OTP, symbolizes their delicate and sweet romance. Even the light blue color for the female historian uniform is distinguished from the male historian uniform.
- The OST is easy on the ear. Some notable songs are "My Dream" sung by Yoon Mi Rae, the queen of OST; "Come Here" sung by Lee Seok Hoon, and "Please Remember" sung by the ML Cha Eun Woo.

Dislike:
- I have not found any

Note:
- Probably should add a tag of noona romance, as ML is 20 and FL is 26. It does not seem a big deal in the story since their age gap is never opposed in the drama, and one arranged marriage candidate for ML is older than him (Sa Hee).
