Zhang Yueru and Zhang Xingyi are the daughters of Zhang Wen, the chairman of Qingya Music Academy. As Zhang Wen grows older, he promises that whoever has a successor first will inherit the academy. Zhang Xingyi, determined to inherit the academy, marries early in an attempt to have a child. However, Zhang Yueru, who has no intention of inheriting, unexpectedly has a one-night affair with Gu Beicheng and gives birth to a son, Tuan Tuan, before Zhang Xingyi. Filled with jealousy, Zhang Xingyi secretly abandons Tuan Tuan. Seeing neither daughter has a successor, Zhang Wen demands they adopt two boys from an orphanage. Whoever passes a music test will inherit the academy. To everyone's surprise, Zhang Yueru's adopted child wins. Unable to accept this, Zhang Xingyi attempts to kill Zhang Yueru. When they both wake up, they find themselves reborn on the day they adopted the children. This time, Zhang Xingyi adopts the child that Zhang Yueru had adopted in her previous life.
