She was originally the lowest female handyman in the Imperial Hospital, living as humble as a dust in the world. A substitute marriage allowed her to put on the mask of a princess and step into the bloodthirsty prince's new house.
She originally thought that what awaited her was a poisoning and escape on the wedding night, but when the prince lifted the hijab, he was stunned by a light mole in the corner of her eye - "You look so much like the person who saved me ten years ago."
A piece of broken jade revealed two dusty past events. The young man who was dying in the abandoned palace of Shanglin Garden ten years ago, the young daughter of Queen Xiaozhen who "died" twenty years ago, and the half of the token with the hibiscus flower engraved on it... She was shocked to realize that she might not be a substitute at the mercy of others, but the one who should have been a golden branch, but was erased by poison and conspiracy - Princess Duanhui.
From medical girl to stand-in, from princess to princess, she steps on the edge of a knife every step of the way. The queen's pressing step by step, the witchcraft conspiracy of the Blackwater Department in the north, the deadly poison lurking in her body, and the prince who dragged her into the storm but protected her with his life...
This is a story about identity, blood feud and redemption. When she finally stood in front of the Qianqing Palace and accepted the canonization as "Princess Duanhui", she knew: the real storm had just begun.
