That guy came for me, zheng ping. Your calamity is... People call me level headed, so i will not forget it. He tells zheng that the day before, he and his grandfather tracked down a kidnapper and found that the kidnapper was a human trafficking gang, not a petty thief or pervert. They called the police, and they saw that the gang was breaking the legs of one group of children and removing the corneas of the other. zheng tells him to go out to ask for help, and zheng runs outside and shouts to everyone to come help him. He says that sometimes as long as he helps others, people will come to help him too, and sometimes, they will hide as much as possible. He doesn't come back, and he says that only grandpa deserves to be called at that time because zheng is not there, no one was in the way and he is just doing his best. It is that time that zheng gets sick and dies in the hospital, and all of zheng's life, he has blamed himself the most for his grandfather's death, and if only he had been there, he could have helped zheng. If he really wanted to be a hero, he says, he would go back to the time and fight with zheng, so he could change the past. He asks zheng if there is still a chance, and says that he will end zheng before zheng realizes his need for life.
