Please Prove You Exist

From that night on, Zhou Yan discovered that there were some invisible "promises" in this city. Someone gets married, so she becomes someone's wife. A street has been called a street for decades, so it really belongs to the city. A name is remembered by enough people, and the world recognizes the person's existence. And Zhou Yan can see these words that maintain reality. Even—— Change one of the words. But every time it is changed, reality will be re-determined: Who is who. Where is where. Who should be left behind. As a price, Zhou Yan himself was gradually forgotten by the world. Until one day, 12 million people participated in an online challenge called "Prove You Exist". Seven days later. In this world, there is one more—— People who were never born. He has an ID card. There is a job. There is a mother. I have an ex-girlfriend. There is a whole life. Everyone knows him. Only the birth hospital told Zhou Yan: This person has never been born. And at the same time. Fewer and fewer people still remember who Zhou Mian is. When the whole world doesn't recognize your existence—— How do you prove that you are you?
