This drama.is everything. First time that I liked the Ahjussi character. The trio is indeed awesome! Hoping for season 2 with the same cast. I like how the cases in the drama are based on true crime cases. This drama is a bit like the hollywood movie frequency and I love that movie that I one of my project was based on that movie :) The differences are the radio they used. In the movie the father and son are the one that's communicating while in the drama they don't know each other. The pallettes they used in the drama to transition from present to past is perfect. Best scene for me.is when Ahjussi is crying in the movie theatre while everyone is laughing it was heartbreaking. Even the supporting roles shine in this drama. Best Crime Drama for me. To those who haven't watch it yet I recommend you to watch it to know how amazing this drama is.
