I came to this crime drama because it paired my favorite couple from JUMONG: Song Il-Gook & Song Ji-Hyo. I stayed because I enjoyed how the drama developed & how the detectives solved their cases. The supporting cast (especially Min-Joo's over the top office mates) all handled their roles well. One of the pluses for me was seeing a softer side (& a smile) to my favorite perennial bad guy: Kim Gyu-Chul. The other plus was Insooni's contribution to the OST: loved her Farewell/Goodbye! Overall, this was a very enjoyable drama & by the end, when the story's main issues were resolved, I was glad I watched it.
