I Accidentally Became a Hero

For twelve years, I have been having the same dream. In the dream, I was chopping wood to feed horses, fetching water, and practicing sword practice. I was like a sword-wielding hero in a martial arts novel, wandering around the world, so happy. People around me always say that I am obsessed with reading too many martial arts novels, but the things in my dreams always feel vivid in my mind, as if they happened yesterday. Every time I think of the memory in my dream, I feel inexplicably uncomfortable. I feel like there is a huge emptiness in my heart. I don't know why, so I took advantage of a long vacation in my senior year of high school to go to the place in my dream, and unexpectedly discovered that I really lived such a wonderful life...
