Shūji, a desperate vagrant who nearly kills himself, stumbles into a neon‑lit soapland and unleashes his pent‑up lust on hostess Nanako, his cries of desire filling the steamy room. Injured in a bicycle accident, he awakens in a hospital bed—only to be mistaken for her absent husband by Nazuna, a stunning sexy wife starved of affection. In her softly lit apartment, Nazuna’s trembling fingers and silk nightgown hint at the secret hunger she’s long suppressed. Under half‑drawn curtains, her lace lingerie clings to every curve as his fingertips trace heated paths across her skin. Their lips collide in desperate kisses, each gasp and moan echoing in the intimate gloom as they lose themselves in forbidden ecstasy. She arches against him, offering every tremor of her ripe body to his eager touch. By dawn, mercy and obsession blur, leaving them entwined in a heady haze of passion and deception.
