Suda Masaki's performance as Hiiragi Ibuki is by far the best part of this drama, and the mentor-mentee dynamic he had with every single one of his students was really great. I loved seeing how all the students went through a range of emotions as the drama progressed, from laughing at him at the start, to feeling betrayed, to finally starting to listen, trust, and look up to him.

The female lead is one of the students who definitely plays a larger role than her classmate counterparts, but still doesn't play a very active role throughout the show; with different episodes focusing on different students, sometimes she feels fully sidelined. Not a dealbreaker by any means, but it definitely feels like there's just one main character.

I think the individual themes in the show are really strong, especially when there is a main focus on a student for each lesson, but I'm personally not a huge fan of the final message, of the "killers" being internet bullies. While I understand the message of thinking before you type and not hiding behind a screen, I also feel like Mr. Hiiragi speaking to "the general public" not only doesn't have the same emotional impact, but also feels so broad that his perfect plan starts to feel a little leaky, especially when I think the same lesson of "think before you act" was already given earlier specifically to the class of students, and it worked better then.
