I love this drama so much, i would recommended this drama to anyone who love investigation genre. I think this is the first investigation that i cannot follow up correctly and guess who were the murder correctly. I love it when i cannot tell who was the bad guy correctly. Throughout this drama caught all of my attention and i finished within one day. Another fact that i love about this drama is, it's very detailed and give the audiences for 2 episodes to solve the case. All of the cases here i would say brilliant job for all of them. The first one case gave me little bored but once they solve the case, it amazes me totally how they make the case to turn out very intertesting and cleverly i would say. There are many twised within every case in this drama so, whoever love the twise in investigation drama please give this one a try, you would love it and you can ignore some chessy parts too because the case is very intense and the action of Ayano Go made this drama even more interesting when he has some doubt of the case and correct all the details together and solve it later on. The story is brilliant and also the scriptwriter for this drama is great as well. The cinematography in this drama also just the way i like it to be little dark and little humor in some part. Mostly i would say dark but it was a easy dark atmosphere to watch so, i think anyone could watch this one easlily and enjoy all the cleverly cases. Even though the rewatch value is low because it is the weakness of this genre once you know the answer, the second times to watch it might not be intense like the first time.
