Cheng Ran is unexpectedly reborn ten years in the past, at the Central Conservatory of Music.
A carefully staged performance of “Glitch” at a bar goes viral, its reality-defying melody taking the internet by storm. But it also draws the attention of a mysterious organization.
The group believes music can be used to control people, and is desperately searching for the “key” that will make this possible.
Cheng Ran soon discovers that music's power goes far beyond that.
It can be a warm current that heals the heart, a blade that carries secret messages, and a vessel for secrets powerful enough to shake the world.
As forces in the light and darkness close in, he must keep his hands on the keys and find a way out of the maze of melodies.
