Su Wan, a concubine-born daughter of the Prime Minister’s household, is reborn on the eve of her coming-of-age ceremony. In her previous life, she trusted her hypocritical stepmother, her scheming half-sister, and her jealous aunt, only to be drawn into palace intrigue and condemned to be drowned in a pond. This time, she clings to the financial records and the weaknesses in people’s character preserved in her memories of her previous life. Using her “love of money above all” as a shield, she pretends to obsess over small profits and every last coin, while carefully plotting each move: using her embroidery business to uncover leverage in the household feud, exposing her stepmother’s hypocrisy through flaws in the accounts, and luring the calculating Prince Xiao Yan into her game with her “money-grubber” persona. The two test each other amid a torturous romance: she seeks revenge, he seeks power. Yet the deeper they plunge into schemes and counter-schemes, the more entangled they become. In the end, they uncover royal secrets behind a bloody case from years ago and find redemption for their love and hatred amid the palace storm
