Des:One day, a door was found abandoned in the school hallway. Is that the one you used at the school festival? Its in the way, I thought as I looked at the door and touched it, but the teacher told me to put it away. Having no choice but to carry the heavy door to the classroom, I thought to myself, ``If I open the door like this, it will lead to a girl who is changing her clothes...!! Oh, thats a lie, isnt it? It was a mysterious door that allowed you to go anywhere, including where the girls were changing, the bathroom, and the private toilet room! !
