After staying in this world for so many years, I feel as if I only live in a narrow circle, and I really can't bring much value to others by living in this world. He doesn't know how to interact with others, and he doesn't know right from wrong. I silently hid in a corner of my world, as sensitive as a guinea pig, thinking that hiding would stop me from getting hurt. But when my wounds healed and I wanted to see the light of day again, I suddenly received more serious scars. I saw the colorful trees and flowers around me, and looked up at the sky inadvertently, only to find that no matter how hard I tried, the sky was always gray. Under the gray sky, no matter how beautiful the scenery is, it is redundant.
