A good first few episodes and really bad one at the end

I really liked the beginning of the drama with the originality of the script and the fact that Hee Joo is mute. Her dual personality was also very interesting.

However, after that, the script became empty... Total inconsistencies at the end. The last episode was nonsense: how can we go in heels in a country at war ? Aspects without explanations: the past of the parents of the "good" paik seon ?

Also quite sad that the music in the drama was almost nonexistent.
