Hwang Si-mok's character development throughout the two seasons is like watching a baby grow up, and it's very satisfying and heartwarming to watch. We saw someone who seems to be cold, emotionally void of anything, and a loner in the beginning, but slowly begins to warm up and trust others. So seeing him and Han Yeo Jin at opposing sides of the prosecution and police throughout season 2, especially with them having little to no interactions at all, was a little heartbreaking to see. So surely, most of us cheered when we get glimpses of them together. The same goes whenever Si-mok and Seo Dong-jae have interactions, of which I would have loved to see more given the last scenes they had in season 1.

I just love how the plot was smartly written and well-executed, and props to the writer and director for casting such a solid and incredible cast. So many twists and turns, and the versatility they portray is truly commendable. This just shows that the cast need not to be entirely star-studded/full of A-listers (Bae Doona and Cho Seungwoo are though) to be able to make a drama successful.

The drama was able to excellently portray how the events that took place in season 1 shaped the characters at present. I'd like to believe that the fog in episode 1 was a foreshadowing on our morally gray characters and principles; the deeply-rooted corruption and power play; as well as the never-ending feeling of being lost and frustrated in pursuit of justice. And I'm pretty much in awe at how a motive so simple was made entirely intricate, and has managed to create a domino effect, affecting so many people and in so many ways. And in great detail, too! Even the slightest act or situation that may seem harmless or nothing at all, can bring so much implications and impact on the characters -- all because everyone has different motivations and principles.

The finale was a bit of a cliffhanger IMO, but I'm still incredibly hopeful that there will be a season 3 with how things ended.
