Overall, the drama is all right. It could have been shorter though. I feel like the sections of the female detective doubting/hating the main male lead is kinda long and repetitive.

Romance is not that attractive. I would not ship these two leads. There aren't much romance scene in this drama. (not gonna lie, I skipped the romantic scene between them at the end of the drama lol)

The acting is not bad. Actors are good, but the characters itself are sometimes silly.

I do like Kang Mi Na acting in this drama. She's funny to watch. :)

For Kwon Soo Hyun, this is the first time I saw him acting. He is not bad. I like his Cha Do Won character; it's mysterious but not enough. His sense of justice kinda remind me of character K in Inspector Koo. Both kill people that are deserved to be punished. However, the difference is Cha Do Won also kill the innocent (prosecutor Han). One thing I would change Cha Do Won acting is show more creepy expression to create more mysterious vibe (smiling). His smiling is more of like forcing himself to smile (not natural). It would have been better if he shows more expressions. His expression in this drama is kinda stiff.

One thing I like about this drama is when Nam Han Joon did the criminal profiling. I love criminal topics such as forensic science; so it's interesting to learn how criminal profiling works.

Overall, my rewatch value is 4/10. Story is 5/10. Acting is 7/10. Romance is 3/10. Music is 5/10
