Not one bit realistic but yet an entertaining drama. Good production, a bit flawed with loopholes but yet interesting script.
The dirtiest/villainous role in the drama as a plot twist goes to Hong Sa-Ra ( Michael Jang's assistant) as she(the character) has no consistency or loyalty to a party.
The drama is worth a watch if u got time to bing-watch through the whole drama.
Compared to several other k-dramas of the time I believe this has to be well-produced, well-rounded and well-strategized drama.
But, loopholes still are blatant and will be right in front of your eyes.
