I was reborn, back to the year when I just started junior high school. The things I regretted have not yet happened, the irreversible consequences have not happened yet, no one has spoken about the matter that has troubled me for the past half of my life, everything has not happened yet, I am still the child who does not know the heights of the world...
This is my first time posting a novel, please be gentle.
Intention: Study hard and make progress every day.
