The room was dim, scented faintly with cinnamon and wax, as Y/N struggled against the soft but unyielding bindings. Rin and Len hovered nearby, their bright smiles twisted with obsession. “You remember throwing us away, don’t you?” Rin whispered, tilting her head as if studying a broken toy. Len circled behind Y/N, humming a deceptively cheerful tune, his eyes glinting with a manic focus. Every movement they made was deliberate, a sinister choreography designed to keep Y/N terrified yet helpless, trapped in the very place they had once been discarded from.

Hours blurred into a cruel ritual. Rin and Len worked in tandem, their obsession manifesting in careful, meticulous alterations—threading porcelain-like skin over Y/N’s arms, adjusting her eyes to mimic their own unblinking gaze, and weaving a permanent smile across her lips. They whispered promises of eternal companionship, their voices sweet yet hollow, as if trying to convince both Y/N and themselves that this transformation was an act of love. Each layer of their “gift” drew Y/N further from the human world, molding her into a living doll, a humanloid shaped by their unrelenting devotion.

By the time the transformation was complete, Y/N could barely remember her old self. Her body and expressions were no longer entirely her own, and the faint pulse of her humanity was drowned out by the twin’s obsessive care. Rin clutched her hand, Len’s shadow looming over her as they cooed, “Now you’ll never leave us again.” The room, once a place of fleeting memories and abandonment, had become a shrine to their obsession, a trap where Y/N would remain forever, a perfect reflection of the dolls she once discarded, bound eternally by the love-tinged madness of Rin and Len.
