Nanami Kawakami has moved to the current house due to her husband's work. Perhaps for that reason, she had no friends and was busy with her housework as a full-time housewife. One day, on the way home from shopping, she helps a neighborhood kid carry a heavy bag. As a token of gratitude, she invites her to her house and treats her to snacks. Nanami was happy to have no children, but the children had different expectations.
