Ssangdungiui Neungyong Buin

Within the affluent and influential Bae Deok Lee clan, Ji-Hye is a newlywed of merely three months who harbors a fierce ambition. As the youngest daughter-in-law, she is determined to elevate her husband to the position of eldest son, thereby securing her own status as the future matriarch of the powerful family. Her relentless drive sets the stage for a high-stakes struggle within the rigid hierarchy of their elite household. However, on the eve of the Shinrye ceremony—a sacred tradition requiring married couples to abstain from physical intimacy in order to purify themselves—Ji-Hye's carefully constructed plans are derailed by a shocking transgression. Her twin brother breaches the boundaries of propriety, initiating an illicit and deeply taboo encounter with his sister during a night meant for spiritual cleansing. Amidst whispered pleas and brazen declarations regarding her potential to bear heirs and shape the clan's leadership, he crosses a line that can never be uncrossed. What begins as a single forbidden act quickly spirals into a dangerous entanglement of lust, familial duty, and dark secrets. Bound together by blood and boundless desire, Ji-Hye finds herself trapped in a fatal relationship that threatens to unravel everything she has worked to achieve. This is a story where ambition collides with the ultimate taboo, leaving the fate of the entire clan hanging in the balance.
