My name is Sayo. I've been married for ten years now. We don't have children yet, and I spend my days constantly tending to my husband's needs. He's like a big child—easily irritated over little things. In this routine, when he leaves for work, I often find myself with nothing to do and too much free time. Then one day, there's a knock at the front door. It's a pushy door-to-door salesman. No one could have imagined that this encounter would become the turning point that drastically changes her ordinary life.
