Su Nanzhi was born with a heart condition and was once told she wouldn't live past 18. But she survived, and with her extraordinary eyes, her heart was trained to remain untroubled.

Su Nanzhi fit the image of a delicate beauty all too well, and she happened to have been nurtured in a rural village for over a decade. Her uncles, brothers, and sisters in the family looked at her as though she were a performing monkey. That is, until this performing monkey shed all her covert coats...
