At a quiet, serene inn, married woman Aki is soaking in an outdoor hot spring, healing her mind. She dated her husband for four years before marrying two years ago, but when touched by men other than her husband, she undergoes a dramatic transformation, as if becoming a completely different person. Contrasting her occasional lonely expressions, the pleasure she feels during her affair highlights her deep, alluring charm. "For me, being unfaithful is a time when I can return to my true self," she says—a statement that symbolizes her complex emotions.
