Shen Zhiwei, a modern-day Chinese medicine practitioner, transmigrates into another world and becomes an illegitimate daughter in the Prime Minister’s household, where everyone tramples on her. She is ordered to marry her elder sister’s intended, the Seventh Prince Xiao Heng, a supposedly foolish, disabled man who won’t live six months, to bring him good fortune.
The whole capital expects her to suffer and become a widow. Little do they know that only she realizes her sweet, obedient, clingy, affectionate husband is hiding an astonishingly calculating mind.
After being framed in the palace twelve years ago, he pretended to be insane and foolish, lying low and biding his time. He commands three thousand secret guards and has spies planted throughout the court. Shen Zhiwei uses her medical skills to protect him and her cunning to root out traitors in the prince’s household. By day, she indulges her innocent little prince; by night, he drops his disguise and entrusts all his schemes and tenderness to her alone.
The Second Prince and Noble Consort Li close in at every turn, and a storm is brewing at court. United as husband and wife, she manages the household, practices medicine, and prepares for what lies ahead, while he plots his revenge from behind the scenes. The foolish prince whom everyone once bullied becomes dark and possessive under her care. He offers her the realm as a bride-price and dotes on her alone. Together, they topple the conspiracies at court and protect a peaceful life together.
