Park Eun-ji has lived an ordinary, invisible life - until she discovers she has a twin sister she never knew existed. That sister, Gong Sa-rin, is the golden girl of Korea's elite, thriving in wealth, power, and privilege at Baekyeon International Academy (백연국제학원), where the heirs of the nation's most influential families are groomed.
But when Eun-ji arrives, she finds Sa-rin dead - and a chilling message from the murderer:
"Take her place... or you're next."
Forced to step into Sa-rin's life, Eun-ji is plunged into a world of luxury, betrayal, and hidden enemies. Sa-rin's broken engagement to Seo Jun-ho , the cold chaebol heir, rival classmates, and families hiding dangerous secrets all threaten to unravel her.
And always watching is the stalker who killed Sa-rin, ready to strike again. Eun-ji must navigate a world where every smile masks ambition, every secret is a weapon, and the price of survival may be her own soul.
