Oops! I Ended Up with My Sister's Man - Episode 15

Two Devin sisters are on the verge of joining the influential Nott family. Ambitious eldest Eliza is promised to the cold, domineering family patriarch; gentle Katie is matched with the family's famous younger son. On their wedding night a chaotic mix-up collapses their plans. With reputations on the line and no other option, the sisters impulsively swap marriage contracts. The exchange buys immediate relief but detonates buried tensions: Eliza must face a loveless alliance she engineered for power; Katie must perform a public role under dazzling scrutiny. Each step forward risks exposure, betrayal, and the unraveling of the family façade. A single choice turns duty into deception, forcing both women to fight for identity, loyalty and the fragile futures they dared to claim.
