What a ride, twist after twist, the show did a very good job with building up the hype and anticipation leading up to the climax event for it to meet expectation, did not disappoint at all. A little unfavorable for them to disclose flashbacks and behind the scenes that's not from the MC's perspective in the middle of the series, making things already known to viewers. A serious mood all the way, large cast with each own significant role to the plot, continuous large singular case, tons of death especially people closest to the MC one by one. Show wrapped it up nicely without any hole and ridiculous ends. Some serious acting skills displayed by a few side characters. Main instrumental OST is good. Glad they didn't over focus the romance between MCs like in Flower of Evil. Not a single second of this show felt too fictional until I will call bullshit, very well immersed.
