A husband quit his job and started the dairy farming business he had dreamed of. Until work gets back on track, Rumi, who is said to live alone in Tokyo, is waiting for her husband's contact. However, after a while, I received news that my husband had passed away. Middle-aged workers at a dairy farm, who were her husband's colleagues, came to meet Rumi and were shocked. The cattle have contracted an infectious disease and the farm is in danger of closing. The president of the farm, who had lost money, turned his attention to Rumi's lonely body and breast milk.
