Kanna Misaki, a slender married woman, visits her in-laws' home with her husband to care for her injured father-in-law, who had fallen down the stairs and lost his will to live. After her husband leaves for work, Kanna diligently tends to her father-in-law, gently wiping his body since he hadn't bathed in days. Her tender touch awakens long-dormant male instincts within him. Overcome by the warmth of a woman's care and struck by Kanna's striking resemblance to his late wife, the father-in-law loses control and pulls her into an embrace. Though Kanna resists at first, there's no turning back as her father-in-law's passion reignites his will to live.
