The World Deleted Me, but Not Completely

On his eighteenth birthday, Cheng Yan received a funeral invitation. He is the deceased, his mother is the family member, and he is the invitee. He originally thought someone was playing a prank, until he actually arrived at the funeral home and saw his portrait hanging in the center of the mourning hall, with relatives and friends sitting below and crying, and there was a person who looked exactly like him lying in the coffin. Cheng Yan walked to his mother. His mother stared at him for a long time, and finally asked: "Who are you?" Since that night, the traces left by Cheng Yan are disappearing little by little. There is no name on the ID card, no one can be found in the photo, and all the contacts on the phone have become unfamiliar numbers. Even the room he had lived in for eighteen years began to look like no one had ever lived in it. Everyone accepted a result. Cheng Yan is dead. Only Xu Mo still remembers him. She told Cheng Yan that before 5:17 in the morning, he must prove that he outside the coffin is real. Otherwise the body would take away his name, his identity and his past. And he will be completely deleted from this world. However, the world probably missed one thing. Cheng Yan was not ready to accept his fate yet.
