“Quit working as a nurse!” “All right, I will!” thus began the married life of Yasuo and Keiko. But the reality is harsh. Keiko even had to work on the first night after her marriage. Ten years later, the married couple is still at it. Yauso tends to the house and their children, while Keiko sacrifices family life for life as an overworked nurse. One day, after Keiko comes home utterly exhausted and dejected from her work, Yasuo makes up his mind and writes a letter of resignation in her place. Upon learning of this, Keiko angrily declares that nursing is what she lives for and she will keep on working. Realising that that is one battle he will never win, Yasuo sends a letter to a newspaper -- “Nurses’ husbands, aren’t you having a hard time? Get together nurses’ husbands. Contact me.” There is a tremendous response. This leads to the formation of many unions of nurses’ husbands throughout the country.
