Tang Xia, a naturally rebellious girl, grew up with Lin Dian, a well-known all-around genius. The two spent their childhood together but were forced to leave because of an unexpected grade skip. A shocking incident also occurred in Tangxia's family: her father died in a car accident on the way to send his sister to college. My sister's life or death is uncertain. My mother has also suffered from mental illness since then. Tang Xia survived in this prosperous and impersonal city (Beijing) by singing and singing in bars. At the age of 14, she was already a notorious gangster. She smokes, drinks and fights. Since the store manager's return education required high school, she had to skip a grade to high school. None of the six classes in the first grade of high school were willing to accept her. I found out on the spot that it was her. Let her join the class despite other people's dissuasion. And determined to transform her and make her a top student. Tangxia also gradually turned from opposition to acceptance. He even started to like Lin Dian little by little. Unexpectedly, she met Lin Dian's ex-girlfriend Xia Jingshen on the way to Shanghai, the person Lin Dian had been looking for.
