Qin Shu was once the daughter of the Qin family, but was rejected when the real daughter Su Yun returned. After discovering that she was pregnant with her fiancé Lu Jin's child, she left her hometown. For four years, she changed her name to Song Shu, regained her life with the help of her best friend Song Qi, and gave birth to her daughter Duoduo. After Song Qi died to save her, Qin Shu became independent and strong. Four years later, Lu Jin, his biological brother Su Cheng and his adopted brother Qin Sheng came one after another, full of guilt and wanting to make amends. Su Yun also came to provoke him again. But Qin Shu is no longer the dodder who relied on others. She clearly rejected the entanglements in the past, relied on her own efforts to achieve success in the field of music education, and finally started a life of her own with her daughter.
