A husband quit his job and started the dairy farming business he had dreamed of. Until the business got on track, Rumi, who was said to be living alone in Tokyo, waited for her husband's contact. However, after a while, I received news that my husband had passed away. The middle-aged workers at a dairy farm, who were her husband's colleagues, came to see Rumi and were shocked. The cattle had contracted an infectious disease and the farm was in danger of closing. The president of the farm, who was losing money, turned his attention to Rumi's lonely body and her mother's milk.
