Ordinary girl Alia, desperate to raise money for her grandmother's medical expenses, was coerced by her older sister Isabella into taking her place for a night with chaebol CEO Christian. She fled hastily afterwards, leaving behind a pearl earring that became a crucial clue. Christian, recognizing the scent, bite marks, and the earring, realized the person that night was not his fiancée Isabella and began a secret investigation. Isabella, harboring ill intentions, faked a pregnancy and repeatedly framed Alia. After her schemes were exposed, she set a fire, attempting to silence Alia. Christian rushed into the blaze and rescued Alia, and they confirmed their feelings for each other. Unexpectedly, Christian's business trip ended in a plane crash, and he was rescued by Swiss heiress Victoria, who then subjected him to deep hypnosis and altered his memories. Alia gave birth to twins, took sole control of the company, and traveled to Switzerland, disguised as a therapist, to awaken her beloved. Christian instinctively remembered Alia, and after recovering his memories, he dealt with Victoria. Finally, he and his wife and children lived a stable and happy life together.
