Kengo, fleeing to his relative's temple due to overwhelming debt, meets Midori Nashiro—the temple owner's daughter who has become a nun. Cloaked in her robe and nun's hood, her alluring charm deeply stirs Kengo's heart. Yet bound by her role as a trainee monk and a nun, romantic love is strictly forbidden. Midori herself harbors deep anxiety about completely renouncing her identity as a woman. One day, while a young, virile gardener is working in the temple garden, Midori feels an intense physical desire, succumbs to his seduction, and passionately indulges in pleasure she had long forgotten. Witnessing the act, Kengo is consumed by jealousy, calls Midori out at night, and the two become entangled in a new, turbulent conflict.
