fun-fact. show based on real events and the first korean profiler himself was present during the filming!! it's a story of the first profiler in korea,based on his book from my knowledge, and as a citizen of a country where we still don't have any profiles i find it pretty educational too. i rewatch this kdrama now, and i have to say that it's as interesting as it was and maybe even more. characters, their thoughts, the process of investigation itself - everything is perfect. and i have to say that after a year of listening to this soundtrack i still love it!! must watch!
