His wish is very simple. He just wants to understand human emotions and live an ordinary life, not as an artificial human or an intelligent optical brain.
Perhaps God heard his prayer, and a destruction allowed him to travel to the earth tens of millions of years ago.
Here, he has no special powers and no sense of style. All he has is the profound but not modern knowledge in his mind, and the huge and precise calculations of his brain.
He started to go to school and after school just like an ordinary high school student, living a life between home and school. Occasionally, he would go out to work part-time to experience feelings.
But he met him.
From the initial game of teasing to the various pursuits later on, when did the heart of the game of human beings start to be tightly tied to the other person?
Looking back on the decades he took him with him, he realized that perhaps the meaning of this time travel was to meet him.
Meet - get entangled, and then never let go for the rest of your life.
