This drama is mainly about a detective who was once a police detective but demoted because of a case. He's a genius - like detective who was actually trained to be so genius - like. In the drama they try to solve this mysterious case while they also solve other cases. Here's the thing the drama was quite good but not really good at the same time. It's one of those dramas where you'll say well ok I've completed it without having to push myself and I don't regret watching it but it's not something I'll keep in mind. Thus my overall rating is between fair and average. Renbutsu Misako's and Matsuda Shoda's acting was really good and also the acting of the other actors was really good. The music as far as I listened to them was good. The not so good aspects: It's the typical drama concept of these genre. You have a rather big case which is followed throughout the drama and then they also solve each episode a case. In this drama what disappointed me was the great final of the drama. It was rather so so compared to the exiting undercover investigations our main lead had. The good points of this drama are Matsuda Shoda!, good detective story! well-acted drama!
