I think the issue here was the writing of the characters. I love watching crime dramas, and I thought I would be really into this based on the synopsis, but it unfortunately missed the mark. I've seen Jang Kiyong in other shows and really enjoyed his performance, but his character in this one totally fell flat. You're waiting for something to happen between him and the female lead, waiting for his cold exterior to crack, and you never really get that. His character isn't very likeable, and even though you're rooting for him, you're not really sure why.

I think they also tried to do a bit too much weird worldbuilding and almost sci-fi kinda stuff. It felt like it should have been introduced earlier or simplified in order for it to make sense. I feel like there was a lot of potential wasted on this one.
