After I saw the casting and the trailer I was really excited to watch this show and thought it would be another thriller masterpiece. However, it turned out for me to be a bit disappointed. It's definitely not a bad show and I still enjoyed it overall but I just couldn't help feeling sad that I didn't like watching it as much as I thought I would.

The acting and casting is on another level with Choi Woo-sik and Son Sukku as the main characters. Nevertheless, I wished for more screentime of Lee Tang (played by Choi Woo-shik) because I personally thought the thriller was going to be a bit more through the eyes of the killer than the police officer. Because of the lack of screentime I found it difficult to relate to the character or at least understand his traits a bit more.

The first episodes were all great and I couldn't wait to watch the show further but later on at approximately episode 5 and following I got a bit bored and it felt really slow. I personally didn't like the adding of Song Chon as a character but I do understand that he had to be there to make the story clearer. I simply wished for more thriller aspects. However, the ending really got me and I'm hoping for season 2!!!

(I did this review only based on the series I did not read the webnovel it's based on)

All in all, the drama disappointed me even though it may have been because of my high expectations.
