One of the best dramas of this genre (and I don't like this genre at all). Drama may seem slower at the start but its required. Followed the novel very closely but brought it to life even better with many comedic moments and wonderful acting.
No complicated relationships. A lot of things were properly explored and explained.
Fantastic portrayals of the lead characters by the actors. Amazing chemistry (CP) between them as well. All of the supporting cast were solid in their acting.
Strong female with an equally strong male in partnership together. Story/Plot had points where it was tear worthy but also imbued with comedic moments.
BGM music was very adept and well suited. Costume design was really good with no weird headdress like items and makeup was subtle. Production quality and CGI were also good.
Oh yes and a special and happy ending that is very different from the usual of this genre.
Something I will re watch again and again.
