The imperial harem and the court are deeply intertwined, with women caught up in the turmoil.
Female lead, Wen Yao: The daughter of Grand Tutor Wen Huaijin, she has been intelligent and decisive since childhood and is skilled in chess and strategy. Gentle and dignified on the outside, she is sharp and formidable within. When her family becomes embroiled in the succession struggle, she is forced to enter the palace as a consort. But step by step, she grows from a pawn into the one who moves the pieces.
Second female lead, Wen Wan: Wen Yao's elder half-sister. Gentle and considerate, she shares a deep bond with Wen Yao. But after an imperial marriage decree draws her into the princes' rivalries, her path gradually diverges from Wen Yao's.
