Two years into marriage, Aya is troubled by a husband who cares only about work. His boss Ozawa, a close family friend, sees the strain and proposes a hot-spring trip. When Aya's husband cancels for work, she travels with Ozawa and his wife instead. Heartbroken, Aya drinks heavily at the inn's bar, then clings to Ozawa as he helps her back. Drunk and lonely, she asks for his body; after some hesitation, he accepts, and they lose themselves in an intensely intimate affair.
