A fallen heiress Charlotte signs a contractual marriage with wealthy heir Mason to settle her family’s debts. At the engagement banquet, a shattered crown and a hidden scheme expose the collusion among the elders. With the line “I’m not inventory”, she voices all her humiliation. She traces the account books and a USB drive left by her mother to unearth the full money-laundering and fraud scandals committed by her parents and stepmother. Teaming up with Mason, she publicly exposes the evidence at an art gallery, toppling two powerful ruling families. Having broken free from their fates as pawns, the two rise to power side by side. Can this bond born from a transaction cast aside all calculation and bloom into pure, equal true love?
