There are always such people in this world who have a very low sense of existence, and Ye Nian is one of them. I saw this sense of presence thing in a certain Japanese anime. Which anime? I tried my best to think about it, but I couldn't remember the title. That's right. I always didn't care much about many things, so I didn't remember it. I only vaguely remembered that some people in it had a very low sense of existence. One day, if they suddenly left this world, no one would remember that they ever existed. When he realized this level, Ye Nian's eyes, which were watching the animation, seeped out transparent liquid bit by bit, and he hugged himself tightly with his hands. This kind of feeling became more frequent when Ye Nian turned 25. On a cold winter night, when he came out of a friend's birthday party, it was almost early in the morning. The streets were extremely deserted, with only the biting wind blowing up the dead leaves and the garbage thrown by unknown people on the ground. Even if he wrapped his hands around himself, he couldn't stop the chill that penetrated into his bones. This sentence came to his mind: I have nothing to do with this world, and this world has nothing to do with me. I felt extremely depressed for a moment, and the smiling face that I had tried my best to arm myself with during the day turned into a dull face at this time. And this sentence kept replaying in my mind like an echo. Although it is a sad thing to admit, it is true. In this empty street and the occasional vehicles, which one of them has something to do with me?
