Shen Nian, an orphan adopted by the Shen family. Since the birth of the true daughter Shen Yu, she has been labeled as "stupid", and she has been reduced from an orphan girl to a rough girl who can be trampled on by others. She hid her beautiful face and extraordinary intelligence, using the mask of chaos as a shield, and lurked silently in the endless cold humiliation and indifference. The smooth pebble on her fingertips was her only comfort, and it was also the edge hidden under the forbearance.
With the Shen family in decline and high foreign debt, she became a bargaining chip for her adoptive parents in exchange for prosperity, and was forced into a marriage with Gu Yan, the disabled legitimate son of the Gu family. Gu Yan is gloomy and taciturn, with a disabled leg, but his thoughts are as meticulous as silk, and there are unknown secrets hidden in his eyes. He could see through the clarity behind Shen Nian's mask at a glance, and a secret war of mutual testing and checks and balances quietly began.
On one side is the Shen family's greedy calculations and the real daughter's jealousy and making things difficult; on the other side is the Gu family's secret puzzle and Gu Yan's every step of temptation. Shen Nian uses the marriage as an opportunity to break the situation, secretly plotting chess pieces, and regaining her edge: she wants to tear apart all disguises, expose the dirtiness of the Shen family, explore the truth about the Gu family, and reclaim all the dignity and freedom that she is owed. When the fake and stupid adopted daughter loses her mask, and when the disabled legitimate son shows off his talents, this counterattack that uses fate as a gamble will eventually amaze the audience.
