Sana, once living a happy married life, suddenly finds her world shattered without a sound. Her surroundings are stripped of all familiarity, leaving only an empty, lifeless room. A sinister chain binds her wrist, and standing before her is a man she recognizes—her former lover. He is obsessive, exuding an aura of madness. Under his control, she is subjected to extreme acts of rape, torture, confinement, and training, gradually transforming into a submissive sex slave, reduced to nothing more than his obedient toy. Even as she is repeatedly raped before her beloved husband's eyes, her mind succumbs to pleasure, sinking deeper into darkness. This is the erotic story of Sana, a married woman imprisoned in the depths of inescapable madness.
