New fathers and brothers due to mother's remarriage. Everyone seemed kind, and I had no doubt that happy and lively days were about to begin. One day, when Sumire went to the bathroom, her father interrupted. I tried to give it up first, but my father's target was Sumire's urine. Sumire, who was threatened with her grandmother's tuition and hospital fees as a shield, urinated in front of her father while scared. Later, her brother comes to comfort Sumire, who is confused in her room, but the brother is also looking for Sumire's urinal.
