On the side of the road, Nana collapses, feeling unwell. A passing man notices her condition and, concerned, offers to escort her home. As he helps her up, he suddenly realizes her blouse is completely sheer—his eyes widen in shock. Later, once she feels better, Nana changes into loungewear, but to his disbelief, it's also see-through, leaving him unable to avert his gaze. Drawn in by her bold charm, the two begin to spend intimate time together. Set in a calm, relaxed atmosphere, the story unfolds as their connection gradually deepens.
