In the Primitive Era, the Struggle of Life

There's nothing wrong with eating three meals a day, it's just a little boring. Meeting new people, knowing new things, and living a better life are my pursuits, just like ordinary people. Maybe I am living a good life, and my friends think so too. I am lucky, but not happy. More than once I pondered the meaning of my existence. In the noisy street with people coming and going, I was like a fish swimming against the rapids. The river water was cold and biting, and it turned into something as sharp as a dagger, cutting through my thoughts and pressing against my throat. There are many people around, but the feeling of loneliness lingers. I know I'm thinking nonsense, but my brain is a thing that can move on its own. The doctor in a white coat came to me with a syringe, and the transparent liquid was injected into my blood vessels along the syringe. The medicine worked very well, I felt calmer than ever before and said thank you. I asked the doctor a question that had been bothering me for a long time. "Is the world as big as what I hear and hear, or as big as what I think about." The doctor frowned, feeling that it was difficult to answer this question. This was the strangest mental patient he had ever seen. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
