Loved the action and political stuff and all that, Ji Chang wook had another great performance but the most outstanding part of the whole show was the female lead, Song yoon-ah! Her characterisation and acting was brilliant! She aced it as Choi yoo-jin.
However, what I didn't like about the show was that despite how strong the chemistry between Kim je-ha and Choi yoo-jin was, it was disappointing that they didn't get more screentime...
I didn't like how An-na out of nowhere appeared and how fast Kim je-ja actually ended up with HER! She had a weak characterisation and was annoying to be honest....
Until the last episode I expected something to happen between Choi yoo-jin and Kim je-ha but nothing...
What a pity that such a strong chemistry between a bodyguard (K2) and a strong female character as a position as Choi yoo-jin didn't get what the audience actually expected and wanted...
