Hannah is an ordinary delivery girl whose life falls apart after her boyfriend betrays her and tries to hand her over to a ruthless debt collector. Just when she has nowhere left to run, she is saved by Cedric, the powerful CEO of the Benedon Group.

Cedric offers Hannah an unusual deal—pretend to be Ivy Bailey, his nephew’s missing fiancée, until the truth behind her disappearance is uncovered. With no better choice, Hannah steps into Ivy’s identity and enters the wealthy Bailey family, where every smile hides a secret.

As Hannah struggles to maintain the deception, Jenna, Ivy’s ambitious sister, becomes convinced she is an impostor and does everything possible to expose and destroy her. But the deeper the investigation goes, the more shocking the truth becomes: Hannah may be the real heir everyone has been searching for.

While family secrets and inheritance battles threaten to unravel everything, an even more dangerous complication emerges. Cedric finds himself falling for Hannah—the woman the world believes is his nephew’s fiancée—turning a carefully planned disguise into a forbidden romance.
