"This is the scent of Nanase-san..." Unable to resist, Yoshioka, upon finding Nanase's underwear in the laundry basket as he was about to take a bath, had to smell it. For Yoshioka, who had harbored feelings for his friend's mother, Nanase, since childhood, staying over at his friend's house tonight was a rare opportunity to get close to Nanase. Yoshioka became intensely aroused by the lingering scent of Nanase from the underwear. He had reached his limit of restraint. When confronted by Nanase after she discovered this scene and questioned him, Yoshioka finally unleashed his long-held feelings.
