"You can think of me as your mother," Mutsumi (Mutsumi Toyokawa) said to her son's friend Kenta, who had grown up without knowing his mother, to cheer him up. Mutsumi's words were casual, but they held a special meaning for Kenta, who has fantasies about what a mother is. What does a mother's warmth feel like? Mutsumi's words made Kenta unable to suppress his desire to be pampered by his mother, so he went to see Mutsumi the next day.
