Is This Time Travel or Rebirth?

I rode the wind and waves all the way from a small county town to become a double first-class student. When I was young, I thought about coming out as gay when I was rich and capable, and finding a girlfriend to live a normal life. However, after staying in G city and working for many years, not only could I not find a girlfriend, I was under great pressure with mortgage and car loans, and my career was not smooth. In my early 30s, I was forced to find a girlfriend due to pressure. I married a man and had children. I thought I would live an ordinary and boring life like this. Who would have thought that a car accident would make me go back to high school. After reading countless time travel and rebirth novels, I was at a loss. After thinking about it for a long time, I still couldn't figure out whether I was traveling through time or being reborn... This novel and its characters are purely fictitious.
