A little girl who became blind at the age of 2 - Tao Zhihan. Her parents' indifference and her brother who is an autistic child have made her live in sorrow alone. Her father is a high school teacher and educates her at home. When she was 12 years old, after completing the family's high school courses, her father finally decided to send Tao Zhihan, who had no emotions, to the school. In the third grade of junior high school, she passed a special examination and was directly promoted to the senior high school. The third grade of junior high school made her pass what she liked but never dared to imagine. She was very happy in the wonderful life, and finally understood that living is good. A lot of things happened to her classmates Ning Shuojie and Da Xiqing, and they met Ning Shuojie's group of good friends before class in the third grade of junior high school. She thought that happy days were about to begin. But because of a sad metaphor with Ning Shuojie, I finally understood this sad metaphor in Ning Shuojie's "I like it" regret without saying anything. After the pain, I finally grew up and magically met another important person in my life.
