I took a deep breath of air and felt so comfortable. It was late at night, everything was silent, and I was the only one who didn't feel sleepy at all. I stared blankly at the sky, thinking about something, but I didn't know what it was. For a long time... I felt an inexplicable bitterness in my heart, and I felt like crying. I was so lonely. In a daze, I felt that my life was empty, lost, and desolate. I can't tell if I have an optimistic and strong appearance. Even though I laugh and laugh with my classmates during the day, greet them, and face them with a generous smile, I am still lonely, young, and sad... I am used to deeply hiding my inner fragility. I don't want their sympathy. I only leave my tears to cry alone. I don't want people to know my heartache, and I don't want people to feel the shadow on my heart.
