Liu Heyang's nightmare in life is nothing more than the tragic disaster he personally caused fifteen years ago. This incident followed him like maggots in his tarsus, torturing him every night.
After Shu Yun experienced a car accident that she would never forget when she was ten years old, she lost her only twin brother, and her family was broken up. She traveled around the world with her mother. She knew that her mother had always been unable to let go of her brother's death, and her greatest hope in this life was that the murderer who caused her son's death would get the punishment he deserved. Shu Yun promised his mother that he would definitely get what she wanted, so he traveled thousands of miles to return to the place that made her sad and disappointed to complete his plan.
