Two years have passed since Yumi lost her husband, and while her emotional wounds are healing, she never feels lonely—thanks to her nephew Ataru, who frequently visits, always attentive to her feelings. One day, Ataru catches Yumi in a compromising situation with Terazawa, her late husband's former subordinate. After that incident, Ataru begins seeing Yumi as a woman, and his changing demeanor starts reminding her of her deceased husband. Gradually, Yumi finds secret pleasure in subtly provoking Ataru's lust whenever he comes to visit.
