Through a coincidence, Mu Xiao Xi met Kong Chen Yi, the male god of music. Mu Xiao Xi originally thought that they would never meet again, but the school celebration party once again narrowed the distance between the two. As their understanding of each other deepened, they turned from friends to ambiguous and finally to lovers.
After graduation, Mu Xiao Xi followed Kong Chen Yi to Beijing. The problems of work, life and career caused troubles and contradictions in their relationship with Xiao Xi choosing to leave. Many years later the two met again at an event.
