Yamagata is a middle-aged real estate sales manager. One day, a Twitter account that appears to belong to him seems to incriminate him for a murder of a young woman. He knows nothing about the account – but an online outrage declares him a dangerous criminal, and he ends up running for his life, both from the police and clout-chasing YouTubers. A body of another murdered young woman turns up at his house, and he receives an accusatory letter from the one who has framed him. But who would do such a thing? He's well-liked by everyone… or so he thinks.
