Highly recommended for those looking for fast-paced police procedural with time jump element.

What I like

1) Acting - Cho Jin-Woong was the standout performer out of the three leads. His facial expressions were on point that I cried during one of his scenes (when he was so desperate). Kim Hye-soo and Lee Je-hoon were great in their roles too.
2) Great writing - It was stressful at times because I felt for Lee Jae-han, who couldn't just trust anybody.
3) The connection between three leads - Detective Lee Jae-han-Park Hae-young connection is so sweet.
4) Engaging plot including sub-plots - This drama is plot-driven. I love how the mini cases are interwoven with the big case.

What I dislike
1) The ending - I want to know what happened to Detective Lee Jae-han.

Favourite scene
The bomb scene threw me off guard and made me panic!
