After school, the three years of high school are ordinary, but they are the most unforgettable time in every youth. It seems that every child has complicated thoughts and is looking for a little oxygen of his own amidst the heavy pressure from teachers and parents, and Jiang Yuxi is no exception. She was once introverted and autistic, but she worked hard to become cheerful. She entered a key class in an ordinary high school and became "popular" in the hearts of adults, but she was unwilling to work hard to resist. Even at the time, she didn't know what she was resisting. So during these three years of high school, Jiang Yuxi had a wonderful dream. In the dream, she met several sunny-faced teenagers, and worked together to weave her own music; in the dream, she had some heartfelt friends who shared her unique sorrow during that time; in the dream, she finally slowly discovered her heart. After opening her eyes, even though she still occasionally felt inexplicable sadness and confusion, she could try to move forward with a smile.
