One day a door was thrown away in the school corridor. When I was looking at or touching the door, "Is it the one I used at the school festival? It's annoying," the teacher told me to put it away. I had no choice but to take the heavy door to the classroom and wonder what happened, saying, "If you open the door like this, you'll be connected to the girl who is changing clothes ... !! It was a mysterious door that could go anywhere, whether it was a girl changing clothes, a bathroom, or a private room in the bathroom! !!
