Synopsis：On Eun-hye and Joo-won’s fifth wedding anniversary, what should have been the happiest night of their lives turns into a nightmare when Eun-hye’s stepsister, Min-jung, crashes the celebration. “He’s mine now. Give him back.” Min-jung’s deranged outburst drives the pregnant Eun-hye to the breaking point, and she collapses on the cold floor, losing her unborn child. Yet Joo-won, indifferent to his bleeding wife, turns his back on her and walks away with Min-jung in his arms. Watching them leave, Eun-hye finally decides to end the toxic marriage she has been clinging to alone. Only after Eun-hye disappears without a trace does Joo-won begin to uncover the chilling truths she left behind—the real face of the Min-jung he trusted, and the living hell Eun-hye silently endured. Can he ever turn back time and save this shattered love, or is it already too late?
