Three years ago, Kiyono lost her husband, Kazuichi, and has been working hard to support Keita, who is attending university. Keita has also found a job. Now that things have settled down at work, he asks Kiyono to reduce her part-time work so that she can relax. However, Kiyono, who had been hiding her loneliness by working hard, feels a hole in her heart as soon as she reduces her part-time work, and she masturbates while fantasizing about being embraced by Kazuichi. Seeing this, Keita can no longer contain his feelings, and attacks Kiyono, who has fallen asleep drunk. Kiyono's resistance is no match for Keita's, and he ends up violating her. From then on, Keita continues to push her down and desire her body at every opportunity, hoping to get Kiyono to understand his feelings. Will Keita's feelings reach Kiyono?
