About the title
Ren Xiaotian is a perfectly ordinary boy living with his father, with whom he constantly argues. The father wants the boy to spend more time practicing piano, while Xiaotian himself dreams of having a real friend. One day his dream comes true: a toy panda starts talking to him. It turns out to be no ordinary toy but an alien disguised as a small plush panda. The boy names the alien Mozart, after the great composer, and gains in him a new best friend, thanks to whom he even manages to improve his relationship with his father. But Mozart did not come to Earth by chance — what exactly is the alien guest's mission?
