Shen Nian is an orphan adopted by the Shen family. Ever since the birth of the family's true daughter, Shen Yu, she has been branded a fool. The cherished orphan became a lowly servant, trampled by everyone around her. She conceals her graceful beauty and remarkable intelligence, using a vacant facade as a shield. Through endless humiliation and coldness, she bides her time in silence. The smooth little stone she keeps in her fingers is her only comfort, and the sharp edge hidden beneath her patience.
The Shen family falls into ruin, buried in debt. Shen Nian becomes a bargaining chip her adoptive parents use to buy themselves a life of luxury, and they force her into a marriage with Gu Yan, the disabled legitimate son of the Gu family. Gu Yan is gloomy and taciturn, his legs impaired, but his mind is meticulous, and secrets lurk in his eyes. He sees through Shen Nian's facade at a glance. Thus begins a silent battle of mutual probing and calculated restraint.
On one side are the Shen family's greedy schemes and the true daughter's jealous torment; on the other are the Gu family's hidden mysteries and Gu Yan's steady probing. Shen Nian uses the marriage as an opportunity to break the deadlock, quietly placing her pieces and reclaiming her edge. She will tear away every disguise, expose the Shen family's corruption, uncover the truth about the Gu family, and reclaim all the dignity and freedom she was denied. When the adopted daughter drops her act of foolishness and the disabled legitimate son reveals his true strength, this fightback, with fate itself as the wager, will leave everyone astonished.
