Schoolgirl Ai was molested by the same old man on the train almost every day. Even though she wanted to change her morning commute to school, she endured being molested by the same old man on the same train because she lived in the countryside and didn't have many trains. One day, my mother introduced me to someone who wanted to get remarried, and it turned out to be that perverted old man... A gentle girl who can't resist when she thinks of her mother is not only on the train, but also at home. The days that continue to be molested begin.
