In the evening, with traces of rain still remaining, in a library that was quiet as the sun set, on a bookshelf against the wall, there was a strange book placed in disorder in the middle of the bookshelf. A woman wearing a long-sleeved sweater similar to a raincoat and a school uniform underneath, with a long black skirt, walked over to take a look and reached out her right hand to grab the book.
