Inspired by social news
After Yao Xiaojie finished her college entrance examination, she asked Qi Chun to meet at the school swimming pool and said she wanted to tell her a secret. In the evening, Qi Chun learned from the news that her best friend had an accident. She couldn't bear the blow and passed out in the restaurant. After waking up, two police officers came to the house. They came to inquire about the case, and Qi Chun had to accept the facts. Three days later, the police came to the door again with the letters that Yao Xiaojie had sent before his death, hoping to learn from Qi Chun about Yao Xiaojie's experience.
