His wife Hiroka has been acting strange lately. I felt this way only after a homeless person settled in my neighborhood. On dinner day, he stopped in front of the blue sheet hut and stared at the homeless. I was suspicious, but I told him I was rude so I decided to go. However, the two we seem to know somewhere, and for some reason, our family smells a bit more and more, and each day our doubts about his wife grow. And when I hugged my wife, I felt a sense of discomfort, and one day I looked into the blue sheet hut and saw a shocking sight spread out.
