Lin Wangshu, the only daughter of the Lin family, was framed by Zhou Yi, the illegitimate son of the Zhou family. After her husband died in a car accident, she gave birth to her daughter, Lin Zhixiao. Lin Zhixiao suffered endless bullying in her childhood and was mute for many years. Shen Yuechen, the heir of the Shen family, came to Qiongshan to support education and took good care of her. Zhou Bosheng, the son of Zhou Yi, was ordered to come and monitor her while secretly protecting Lin Zhixiao. Later, Lin Zhixiao was found by the Lin family through an Olympiad math award-winning video, and returned to her ancestry.
