Fang Ding learned the date of Shen Qingyuan's hospitalization and told Tang Xin. Don remembered that they went to the mountain to take pictures that day. Shen Qingyuan said that he would give Tang Xin a surprise, but this surprise has not been taken out of his pocket. Suddenly, he met two robbers. The robbers hijacked Tang Xin and forced Shen Qingyuan to take money. If he doesn't take the money, he will kill Tang Xin. Tang Xin returned to school after the accident and heard that Shen Qingyuan had dropped out of school, perhaps because of an accident, and everything could be right. As for how to cause Shen Qingyuan's selective amnesia, Fang Ding thinks that it may be Shen Qingyuan's remorse, and that Tang Xin is not protected, but it may also be that he didn't withdraw money at all. Tang Xin immediately opposed Fang Ding's words, and she believed that Shen Qingyuan would withdraw money before her accident.
