A wealthy heiress was drugged by her stepsister and taken advantage of, resulting in a traumatic intimate encounter with the male protagonist. In the aftermath, she took his ring and necklace, left some cash as an apology or compensation, and hurriedly departed. Upon returning home, her stepsister exposed her actions, and under her stepmother's instigation, she was expelled from the family. By this time, she was already pregnant.
Several years later, the male protagonist refused his family's arranged marriage and ventured into entrepreneurship. His mother, pretending to be unwell to compel him to return home for the New Year, pressured him into coming back. To appease his family, he hired a woman and her daughter to pose as his family. Unexpectedly, he encountered the female protagonist, now raising her daughter alone, who had a mysterious ability to influence romantic connections, almost as if she could weave the threads of fate. At her daughter's request, she agreed to accompany him.
Back home, the male protagonist's parents were furious, refusing to acknowledge the mother and daughter, and insisted on arranging a marriage with the stepsister, the very person responsible for the female protagonist's past suffering. During a meeting, the stepsister went out of her way to make things difficult. In a critical moment, the female protagonist's daughter was injured and lost consciousness, prompting his parents to rush her to the hospital. Meanwhile, the stepsister found the keepsakes, claimed to be the woman from that fateful night, and brazenly presented her own child, deceitfully declaring it to be the male protagonist's son.
