Hashimoto takes a liking to Ryota's mother, Yumi, who is his part-time job colleague, and tries to make Yumi an asset by using Ryota. Hashimoto slowly closes the distance between him and Yasuno, and continues to target Yumi's heart. One day, a perfect opportunity came to Hashimoto. After Yumi got on the phone with her husband, who works for her and doesn't care about her family, she started masturbating sadly. After thoroughly enjoying her obscene appearance, Hashimoto visits the Yasuno family again, aiming for a time when only Yumi is there.
