Dark, always dark.
Li Xian has been living in darkness since the third grade of junior high school. His father ran away when he was in the second grade. Later, when his mother worked in public relations, he was exposed by a girl at the school gate. He fell into a darkness more terrifying than poverty. He learned to be a loner and enriched his life by learning sports and Sanda. One incident during the summer after graduating from junior high school left a lifelong shadow on him - being drugged, imprisoned and played with by a girl. In his freshman year of high school, he became mute, an autistic child who did not want to receive treatment, sinking in his own sorrow day after day. In the second year of high school, his mother went to the United States for development. Li Xian moved from Shanghai to live in Lancheng, and started a new life in a fresh and small town.
The unexpected appearance of Yuan Li brought sunshine into Li Xian's life bit by bit. The two people were obviously opposite extremes, but they sympathized with each other in the darkness. Yuan Li dragged him up from the quagmire of life. He learned to live like a normal person, used other methods to relieve stress, slowly took off his armor, became more talkative, and loved to laugh... The two came together through ups and downs, and successfully entered college. It seemed that their life was getting better and better, but... When the news of his mother's death in the United States came, he was once again pushed into the abyss. The symptoms of autism relapse became more serious. They faced pain ten thousand times worse than physical torture, self-mutilation, suicide, and darkness once again shrouded their lives. Yuan Li once again held his hands fearlessly...
"Da Yuan, how many wrong steps did I make for you?"
"You are the end of all my mistakes."
