An Empty Seat (2014)

It has been a week since classmate Wataru Inoue ended his own life. Those who had bullied him, those who had stood by and watched, and those who failed to heed the warning signs, just how did they react emotionally to the death of a classmate? No matter how much they regretted the pain and sadness of not being able to save him, he was gone now, and he was not coming back. And the conflicts and regrets they carried inside will cause the class to fall apart.
