Highly recommended for those who like Crime-Mystery-Suspense series. In the beginning it may seem like a normal series but the story will get deeper and deeper with each ep. Very interesting series.

Plot: An unsolved serial ki*lling case of 13 years ago, comes before the police in a new way.
Why couldn't the police find the culprit 13 years ago? Why did this criminal not commit crime in 13 years? Will they be able to find the culprit?

They showed the past and present (of the series) little by little in a very beautiful way. The making style was great. That's why I enjoyed the series more. This series will give a very different vibe while watching, sometimes there was comedy and the family life of the detectives was also showed due to the need of the story.

The different color grading of past present was top notch. The acting of the main 2 actors was very good. The series created good suspense and mystery.
