Trivia, insights & behind the scenes
Eisuke Naito adapted this from his own novel, written while he was still a university student obsessed with bullying's psychological mechanics.
The 'puzzle' structure directly references Japanese 'karoshi' and school bullying (ijime) scandals of the 2000s, where institutional silence became complicity.
