Mihina, the daughter of the president of construction company "NAMIHI," appears elegant and refined on the surface, but treats those around her with cold severity—especially her low-ranking servant, Umeda. She frequently gives unreasonable orders and displays contempt toward those beneath her in status, causing Umeda constant distress. One day, she coldly snaps, "Don't touch me with your filthy hands," further escalating her cruel behavior. As her unjust treatment intensifies, Umeda finally reaches his breaking point.
