By now, we've seen so many FBI/CIA/NIS/Spy/Ghost movies and series that it's really hard to take this Drama seriously.

They completely missed the mark here. It could have been so great if Everyone was completely oblivious that K was an agent (a ghost at that) and we (the viewers) were the only ones in-on-it... but no... Everyone and their mother in this drama knows NIS agents, ghost agents that are supposed to be "Secret" agents.

If this is fake then it's hard to sit through and believe the rest. The beginning had something, but it's all downhill from there and the ending isn't great either.

I should have dropped this by the middle (ep 7~8 ish) but like a fool I stuck to it only to be disappointed and regret having pushed through to the end. Oh well, win some and lose some.
