The inspirational story of high school student Lin Qingyan who suffered injustice. She got a perfect score in mathematics in the monthly exam, but was publicly accused by her class teacher of plagiarizing the answers of the mayor's daughter Su Yaqi. Despite the doubtful evidence and lack of monitoring, she was still found to have cheated, her grades were invalidated and she was isolated from the class. Faced with prejudice and grievance, Lin Qingyan chose to fight in silence - she turned in blank papers for several consecutive months, causing the class average score to continue to decline, which indirectly exposed the true level of some students' reliance on her guidance. After the Education Bureau inspector intervened in the investigation, the truth finally came to light.
