The murderer built a female PhD student from Yale who was about to get married into a wall. Unable and unwilling to reveal his inferiority complex, he could only remain silent about his motives. The disqualified mother was greedy for pleasure and tried every means to get rid of her daughter. For this reason, she was once called "the woman hated by Americans." Five Korean teenagers disappeared for 31 years after playing together. Many people believe that this was a manslaughter by the military. The student was "obsessed" and followed the female teacher for 15 years. He said: "Don't struggle, it's useless to struggle. We are destined to die together!"... In these bizarre cases, there is not only sinful and gloomy human nature, but also persistence in love and confidence in justice.
