A middle-class girl marries a domineering tycoon for her family’s benefit, always acting gentle and poised to win his approval. He’s content with this obedient wife until he overhears her inner thoughts craving his body after a business trip, shattering his impression and pushing him to file for divorce. Yet constant interactions make him fall for her liveliness. Just as they grow close, he learns she has a twin sister. The sister was meant to wed him but fell ill pre-wedding; the family fetched the abandoned younger sister as a stand-in, promising her money once they swap back. Threatened, the sister forces an exchange. The tycoon spots the difference instantly, chases his wife, and they live happily. The elder sister also finds her own happiness.
