Very interesting mystery, thriller, crime, and suspense drama!! I really liked how the cases and information presented at the beginning were related and connected to the big reveal in the later episodes. Some of the cases were also very intriguing and kept me watching. Although some moments were slower than others, the story was written very well and it also had excellent acting from all of the cast members, especially the serial killer revealed! The chemistry between them all (specifically the investigative team) was also very strong. There was also an unexpected touching moment which just made me so sad. So glad that I gave this drama a try! AND FABULOUS OST!!! Definitely would recommend it!
