I have not read the manga which was this show based on, but I watched this because of good ratings and I really was not disappointed.
Kento Yamazaki is my favorite actor and he proves he can act really well, all the emotions he was able to show was really amazing to see. The other cast was great as well, I liked especially the cold character of Chishiya played by Nijiro Murakami.
Overall it was a really wild ride, I was on the edge of my seat all the time and there were definitely some moments I really did not expect to happen.
I am looking forward to the second season, really good job and I am curious how the story will continue.
