Her husband never realized it... that his wife Aiko was being forcefully taken by her father-in-law and brother-in-law. It started with just a kiss, but it was never an act of pure affection. The persistent, intense, and passionate kiss shattered the married woman's fidelity, leaving no way back. Though she keeps saying "No" with her mouth, her body gradually craves more. She whispers inwardly that it would be fine to make him her lover, yet she can't bring herself to say it aloud. This inner conflict and contradiction form the greatest appeal of this work.
