Intro. The three boys played together, Yuto's aunt went to visit them in the apartment since Yuto's family was very familiar with the other two, Yuto's aunt took a child to visit too, the child needed to study at a school in the city since the child's family lived on a farm, so the family decided to leave the child for the three of them to take care of, the three had no idea how to take care of a child and generally fought among themselves, they were very clumsy so they always ended up doing something wrong.
