First of all, i think they script writer did a brilliant job in this drama. I love every episode of this show just only one that i didn't like but it can be forgiving compare to other detective drama i watches before. The plot is stand out itself from the start to the end, even people who don't like this typof genre still fine it enjoyable to watch because a good story teller they put in every episode. The cast also did a grest job here. The story was great the casts was great and enjoyable and keep you excited in every episode. Recommended whoever put this on the plan to watch list please find sometime to watch this drama, i don't think you will regret after watching this drama. Only weak part would be rewatch valus since its a detective and mystery drama genre once you finish all episodes you already know the conclusion and the truth behind it, however, maybe for couple year if you cannot find any good drama with this genre you can always come back and watch it. The best part would be the story of this drama, i think its a mangs but i never read it before so i have know idea about it before, i think the mangs artist also did a brilliant job here, as expected from 20th Century boy author who wrote Kurokouchi as well. Big thmub up for the author and the script writter for the drama.
