The ten-year class reunion averaged 9,000 per person. I was ridiculed and humiliated by the class monitor because my wife declined surgery. Fortunately, I didn't go. All eight people who attended the party that night died mysteriously, and I became the only suspect. During the investigation, it was revealed that Du Juan was persecuted by the squad leader and others in a tragedy ten years ago, and his twin sister Du Yuyin endured ten years of revenge. I went through dangers to find the truth, and finally assisted the police in solving the case, and used my inheritance to set up a student fund to keep justice and warmth alive.
