Ava, the only daughter of the world's largest financial conglomerate, hides her identity out of love and spends three years as a "humble maid" in her in-laws' home. On their third anniversary, her mother-in-law, trying to curry favor with a so-called "richest heiress" (an impostor), forces Ava to drink foot-washing water, has bodyguards throw her into a trash can during a rainstorm, and forces her to sign a divorce agreement with nothing. Her husband watches coldly and mocks her: "A piece of trash like you doesn't even deserve to polish the shoes of a delicate heiress." Ava walks out of the estate to find a fleet of limited-edition Rolls-Royces worth hundreds of millions waiting for her. She takes off her apron and puts on a crown. The next day, her ex-husband's proud billion-dollar project is suddenly canceled indefinitely. When his entire family kneels at the conglomerate's entrance begging to see the "mysterious female CEO," the one who appears is Ava. Instead of firing them, Ava buys all their assets and turns them from owners into the lowest cleaners in her own estate, forced to scrub toilets by hand every day, with heavy fines for any mistake. At Ava's banquet, the impostor heiress tries to humiliate Ava again by calling her a "maid who stole an invitation," but Ava's father—the real world's richest man—appears and publicly exposes the impostor's plastic surgery and fraud history. The ex-husband's family completely collapses in the face of the truth. They kneel in the rain for three days begging for Ava's forgiveness, but end up heavily in debt, forced to live in the slums and scavenge for food in garbage dumps. Ava stands on a golden balcony, looking down at the ants below. Business tycoons who once ignored her now grovel at her feet. She raises a glass of red wine, and beside her is the top bodyguard who has always protected her (actually another conglomerate heir). He wraps an arm around her waist and declares dominantly: "Anyone who dares to touch my woman—this is just the beginning."
