The production of this drama is beyond ordinary from tv series. I haven't seen this kind of production with tv series before in j-drama, i wish they have more of this kind of production, it's like film production not a tv-series. I have to give loud of appluse to the production team, they did well. The camera angles they used here with the scnes were impact and dynamic. The story and the script were great, i love how they tell the story here. Even though you aren't a fan of suspended and mystery please give this one a try, it's worth a watch. I'm a big fan of this type of drama and Mozu also added the dark tone into it which i love it as well, it's rare to see dark mood and tone in tv-drama these days, so this drama is really make my day. The characters from the 3 main leads were great. The killer and also antagonist were great as well. I have to admitted that in some scnes i was bitting my teenth because i get too excited while i was watching. I think from episode 1-6 were the best part and then 9-10 were great as well. I don't feel like overdone anythingin this drama. The episode 7 and 8 are great too they need these to build up the tension of the drama. Hope you will enjoy this drama as the same way as i do.
