Isabelle, a brilliant designer, suffers a brutal betrayal: her malicious older sister Colette steals her designs, slashes her face, sets a fire to murder her, and even takes the bracelet that proves Isabelle once saved Nicolas, the CEO of the luxury brand ÉLAN. Miraculously surviving, Isabelle undergoes plastic surgery and returns with a vengeance as Séraphine, the heiress of a top haute couture dynasty. Faced with Nicolas—her once-blind fiancé who favors Colette—and Colette’s relentless schemes, she publicly strips the imposter of her disguise, exposes her crimes on live streams, and systematically tears down Colette’s fake persona. When the two are trapped in an ice room and Nicolas finally realizes her true identity, he is consumed with regret. At their grand final wedding, Nicolas teams up with Isabelle to broadcast concrete evidence of Colette’s crimes, sending the vicious sister to prison. What follows is a sweet, relentless pursuit of love as Nicolas sets out to win Isabelle back, no matter the cost.
