Everything from the ost to the starting scene to the casting was perfect. The direction and script compliments each other to bring a story that is relatable and screwed up. Just the same story so many people go through every day, whether its the workplace or school, or even at home, you cant get away from bullies. The feelings of the four main characters especially Junpei and Tomoki's characters all seem equally guilty and innocent throughout the drama so you really think you know something but then something so strange or convoluted happens you're left wondering again and thats what always maintains the suspense. And of course the whole thing reaches a climax that is both thought-provoking and entertaining like the rest of the drama. Just absolutely loved it.
