Upon being reborn, the Book of Destiny gives me two choices: become the abused concubine who is the beloved White Moonlight, or become the powerful principal wife who rules the Marquis's household? Without hesitation, I choose the latter! Liu Baiyue pretends to be weak, sets traps, and frames me, while my husband, Lu Cangqi, favors his outside mistress and even plots to seize my dowry. But I hold three years of secret accounts in my hands, and every entry is evidence of a crime. From the fake pregnancy scheme to the records of embezzlement, I expose every scandal one by one. In this lifetime, whoever wants to put on a grand performance of devotion, I'll use my ledger to turn the entire stage upside down!
