This is the firts review that I make, but I think this series deserves it
I don´t speak English very well, so I apologize in advance for my spelling mistakes

The drama it's amazing in every sense. The soundtrack is great. The plot is the best I've seen in years. After finishing each episode, you feel the need to watch the next episode to know what happens with the protagonists, and who are the murderers. There are moments in the plot that everything happens very slowly, but it's still very entertaining

I loved the interpretations of all the characters. Some of them are very spectacular like Tanaka Kei, in the role of Tezuka Shota, or Nao, in the role of Ono Mikiha.
Some actors I already knew from other series or movies, as a Nishino Nanase (member of Nogizaka46, first generation), Namase Katsuhisa ( what makes a great performance in Gokusen, as Goro ,School Vice Principal), etc.

I think if you like series mysteries ,murders or crimology , you will love this drama. And most importantly, it has an incredible season finale, that leaves you wanting to see the second season
