In order to swallow the property of the Dong Group, Dong Sheng's brutal plot to murder his parents-in-law happened to be recorded by three children. The three men extorted huge sums of money from him to solve their respective difficulties, triggering a game of wits and evil. The novel "Bad Boy", known as a masterpiece of Chinese socialists, was adapted into a phenomenal drama series and transplanted into the personality of a Japanese criminal genius to become more perfect. The brilliant Masuo Okada co-starred in the game of death with several young actors. After "Death Notes", director Shusuke Kaneko analyzed the psychology of the murderer in more detail, pointing out that killing a loved one is the most desirable behavior in the murderer's heart, revealing the current money century, where the hearts of the new generation have long collapsed.
