This drama goes beyond the framework of "legal dramas" and conveys to the audience "What is justice?" and "Is it really a bad thing to be considered evil in the world?" through the anti-hero played by Hasegawa Hiroki. It unfolds rapidly, subverting common sense one after another and trivial opportunities in daily life, such as "missing a train" and "forgetting to bring something home in the morning". Just because of this, justice and evil will alternate, and good people will become bad people, just like the butterfly effect, delivering an unprecedented reversal paradox entertainment story.
