On June 8, 2019, my high school life came to an end. I would like to write this article to commemorate my youth. "I admire small towns in the south, not because of how beautiful they are, but because of their elegance." "I am attached to small towns in the north, not because of how prosperous they are, but because they contain my youth and the fallen leaves returning to their roots." This was her last message to me. After that afternoon, there was no further contact. We haven't said goodbye, so we can definitely meet again, right?
