Ryoko has raised her only son, Jiro, by herself. She ate the bare minimum and took baths with her mother and child to save money on gas...Although they could not be called wealthy, the mother and child held hands and lived a happy life. One day, without warning, the Iori family's bath breaks down. Summer is in full swing...I can't find the money for repairs, so I wonder what I should do while wiping my dripping sweat.
