Kawasaki, who came to visit his friend Atsushi's house, accidentally witnesses Atsushi's mother, Miyu, changing clothes. (Aunt is a beautiful woman, but she wears such big pants ...) Kawasaki was excited to see the fresh underwear of an adult woman other than her mother for the first time in her life. However, that will be revealed to Miyu at a later date. Then Kawasaki who reopened confesses that he is still a virgin and begs Miyu to write down.
