An elderly man fell gravely ill and became bedridden, requiring constant care. Unable to bear the burden, his wife abandoned him, leaving behind Nana. In her absence, Nana stepped in to help with household duties, and the man began directing his undiminished desires toward her. While tending to his helpless body, she submits to deepthroat acts, allowing him to penetrate her throat without resistance, obediently continuing despite the pain. Though these days should be agonizing, the man finds his heart strangely fulfilled. For Nana, who had been abandoned by her mother and made to feel worthless, this relationship may have become something that sustains her existence. Even in this pitiful situation, she seeks love. And through her, the man too reaffirms his own existence.
