Piano teacher Ning Yuan takes his daughter to chase the moon. He is trapped in the memory of his late wife and refuses to leave, until he meets Shu Wanying, a star who is hiding from his fans. She was afraid of intimacy, but he kept his sincerity, but when Zhui Yue said "beautiful sister", he quietly approached her.
But Chu Hua's sharp warning, his best friend's wife's trap, and his secret admirer's deliberate entanglement tore the ambiguity into pieces. Wan Ying ran away when she saw the "intimate" scene. Ning Yuan clutched the truth but couldn't cover up her uneasiness.
It wasn't until the love affair was exposed and capital surrounded Wan Ying that Ning Yuan lifted the curtain - using his time-travel memories to write songs and invest in online dramas to protect her from the siege. She finally dared to hug him and call him "Sir". When he proposed in the piano room, Zhuiyue held up a garland and smiled: "Mom is here!"
The old wounds in the music of the piano were finally warmed by the late cherry blossoms.
