A stormy night when a typhoon hit directly. The Sakamoto couple was supposed to have a dinner party with his wife's colleague, Eriko. However, transportation stopped and my wife could not return from work, and Eriko, who happened to be nearby on business, came soaking wet. The husband, who was fond of Eriko before marrying his wife, could not suppress the excitement of spending time alone. Far from subsiding, the storm intensifies, and the distance between the two gradually shrinks as the sound of the rain intensifies.
