On Mid-Autumn night, Bai Yue's husband He Zhichuan and best friend Shu Yao, who faked cancer, shaved her head. She no longer breaks down or cries, only pricing everything clearly, taking back her dowry and dignity one payment at a time. As fake marriage certificates and fake cancer are exposed one after another, she cuts off all contact with her husband and completely disappears with her critically ill mother. A year later she returns stunningly as a painter, her ex-husband regrets and chases after his wife, but she has long since turned away—not being anyone's moon, I am my own sun.
