One of the best mystery Korean dramas in my opinion. At first I was skeptical about watching it, but when I tried 1 episode, I finished it right away.

It's still the best mystery, thriller and crime drama in my opinion, and I'm eagerly waiting for season 2, but it doesn't look like it's going to happen.

In terms of story, cases, the uniqueness of the dynamics of the story really makes the audience drift into it especially in the last episode.

As for the music, I don't remember the OST at all, but I think the tension in the drama itself made me forget about it hahahaha
