The story of Pei Yunge is a classic tale of betrayal, in which a girl's family chooses their adopted daughter over their own. So when a fan of the story mysteriously slips into Yunge's body, she's understandably out for blood. Starting with the shady director of the psych ward she was relegated to, the new Yunge sets out to punish every sin committed against her in the book. And she hasn't forgotten the wicked Qin Youjiao, who wrongfully assumed her place as the daughter of the Qin family. Just how far will Yunge go to reclaim her rightful place?
