Nancy Moore grows up indulged and sheltered by the influential Moore family, only to discover one day that she is actually the daughter of the far less notable Liddell family.
Her adoptive parents, fearing she will suffer if sent back, support the Liddells discreetly behind the scenes. Not wanting to add to their burden, Nancy quietly slips away to rejoin the Liddells.
But the Liddells, arrogant about their noble status, greet her return with scorn. Her birth parents accuse her of lacking the grace of a "real" heiress, unlike their adoptive daughter, Raine Liddell—who's talented and accomplished.
They claim, "An heiress needs to pick up all sorts of skills and knowledge. You need to learn from your sister."
Later, the Liddells boast about Raine being qualified for the finals of a piano competition, only to spot Nancy on the judges' panel.
They are proud of Raine's status as a designer prodigy, and that she dreams of studying under a national treasure, only to find that figure is none other than Nancy.
When the Liddells warn Nancy to not fantasize about Raine's fiancé, who's also the heir of the Fuller family, the said heir declares his love for Nancy while holding her lovingly.
"When are you going to acknowledge me as your partner, babe?" he asks.
Having made discovery after discovery on Nancy's actual identities, the Liddells finally realize that Nancy is the key to their ascension through the elite's ranks. Regret floods them, tears tracing lines down their cheeks as they plead for her to return.
But the elite Moore family snaps, "Get lost! From now on, Nancy is only a Moore!"
