On a rainy night, ordinary girl Alia accidentally encounters Sebastian, the out-of-control CEO of a conglomerate. She quietly slips away after one night, leaving only a tie behind. After joining Vance Group, she disguises herself as an ordinary intern, unaware that the male lead, who suffers from face blindness, identifies her solely by her unique lilac fragrance and distinctive touch. Her rival, Beatrice, impersonates her and relentlessly torments her, but Alia, with her top-tier financial prowess, steadily rises above the challenges, and her true identity as the heir to the Sterling aristocratic family is revealed. The two unravel the long-held secret of their first rainy-night encounter three years prior. They join forces to settle accounts with Beatrice and their corporate enemies, survive a life-and-death ordeal in a construction site explosion, and finally marry in Westminster Abbey, finding mutual salvation in their journey together.
