This is the best drama I have seen in a long time. It's very engaging almost from the first minute. In each episode you get to know a little more about the mystery surrounding a kidnapping 20 years ago through the stories of witnesses whom the journalist is meeting. The acting is so good, and it's a shame a lot of these people have mostly played in subpar drama with over the top japanese humor. I really didn't know how good actors they were until I watched them here. The drama is only 5 episodes long, so there's hardly any boring parts. The background music is amazing. It's so well done and fits the drama and the mood perfectly. I am really looking forward to the OST being released. Anyway, this is seriously a must-watch. Best japanese drama in a very very long time.
