Who is by your side

Yang Baoshan had a dispute with his wife who came home late from a social event, and drove out in anger. Uneasy, he hit a man (Hanjiang) and was seriously injured while passing through an intersection. Baoshan sent the critically injured to the hospital for treatment. In extreme fear, Baoshan quietly left the hospital on a whim... Yang Baoshan found a bag in the car, which was left behind by the victim of the car accident. There is a stack of letters in the bag, which are love letters written by a college student named Piao Xue to a man named Han Jiang. Yang Baoshan learned that Piaoxue and Hanjiang were a couple who had never met but had deep feelings for each other. In the letter, Yang Baoshan felt that the girl named Piaoxue must have encountered some major setbacks and seemed to have thoughts of committing suicide. With complicated emotions, Baoshan decided to meet Piaoxue, confess everything to her and ask for her forgiveness. When Yang Baoshan went to Ruihe University, he learned that Piaoxue had become blind due to a tumor in his brain that oppressed the optic nerve, and he had been admitted to the hospital waiting for surgery. The blind Piaoxue mistook Yang Baoshan for Hanjiang. The doctor told Yang Baoshan that Piaoxue's illness was very dangerous and could not be stimulated. Yang Baoshan fell into confusion. Yang Baoshan's friend A Lin persuaded him that he might have only killed one person now, but if he surrendered and let Piaoxue know the truth, his life would be in danger. Then he would have killed two people, so Yang Baoshan had to pretend to be real.
