Nanami Kawakami has moved to her current home because of her husband's work. For that reason, I had no friends and was busy with housework as a full-time housewife. One day, on the way home from shopping, a child in the neighborhood helps carry heavy luggage. If you invite them to your house and serve them as a snack, the number of children will increase to three and they will come to play in turn after that day. Nanami was pleased with no children, but the children's thoughts were different.
