In order to swallow up the property of the Dong Group, Dongsheng's murder of his parents-in-law was recorded by three children. The three blackmailed him for a huge sum of money to solve their own difficulties, triggering a series of battles of wits and evil. The novel "Bad Kids", which is hailed as a masterpiece of Chinese social reasoning, was adapted into a phenomenal TV series and transplanted to the character of a Japanese criminal genius, making it even more perfect. The brilliant Masaki Okada co-starred with several young actors in the death game. After "Death Note", director Shusuke Kaneko made a more detailed analysis of the murderer's psychology, pointing out that killing relatives and loved ones is the most appropriate behavior in the murderer's heart, revealing the current money century, and the place where the hearts of the new generation have already collapsed.
