In the fifteenth year of Jian'an, Zhou Yu, the governor of Jiangdong, died young. Zhuge Liang lamented the talent and used the Beidou Formation to help him travel through time and space and regain a new life. He changed his name to Zhou Muyu and became a talented pianist in modern society. At the same time, Xiao Qiao was reincarnated as Qiao Yuwei, a modern college student who is lively and cheerful, loves music, but has no memory of his previous life. Her parents are business celebrities and have high hopes for her, hoping that she will inherit the family business and marry a well-matched kid from a wealthy family.
During a music competition, Zhou Muyu and Qiao Yuwei met, and they felt an inexplicable sense of familiarity in their hearts. After a tortuous collision between the two, Zhou Muyu gradually confirmed that Qiao Yuwei was the reincarnation of Xiao Qiao. He decided to help Qiao Yuwei evoke the memory of her past life, and composed a song full of classical charm "Millennium Love" for this purpose. As the two came into contact, Qiao Yuwei gradually dreamed of some vague pictures, and developed indescribable emotions for Zhou Muyu in her heart.
However, Qiao Yuwei's roommate Cao Wanhui has always been jealous of her talent and happiness. She secretly stole Qiao Yuwei's unfinished music and used Zhou Muyu's trust to make him mistakenly believe that the music was composed by her. Cao Wanhui took this opportunity to get close to Zhou Muyu, trying to replace Qiao Yuwei's position in his heart.
Finally, with the help of Zhou Muyu, Qiao Yuwei finally recovered the memory of her previous life. She finally understood that her fate with Zhou Muyu spanned thousands of years. She bravely pursued her love and came together with Zhou Muyu.
