Liang Mucheng (played by Ady An) was born in a wealthy family and practiced piano since childhood. However, due to a car accident, her father died and her family fell into decline. Her aunt took her to remarry a small shop owner and lived under the roof of others, living a hard life. When she grew up, by chance, Liang Mucheng met Ren Guangxi (played by Vanness Wu), the son of the director of Shengde Middle School, and was involved in his breakup with his girlfriend. Later, the aunt took Liang Mucheng to open a canteen in Shengde Middle School, which allowed her to meet the students of the school and become the focus of attention. Ren Guangxi's parents divorced when he was young, so he had a perverse personality and treated feelings as a child's play. He and his accomplices boasted that they would get Liang Mucheng within one day. However, just when the task was completed, the other party's performance of being quick-witted made him change his original intention. Later, Liang Mucheng accidentally played the piano in Shengde Hall and was caught by Ren Guangxi. The two spent a night together, but were secretly discovered by their adoptive father and made a fuss. After that, the two agreed to play the piano in Shengde Church, but the adoptive father leaked the news, which caused a shock on the campus. From then on, the development of their relationship experienced a tortuous and romantic process...
