In the evening, the drops of rain spread out and covered the windows of the library. Regarding the librarian's room at the service desk, strange events occurred with the disappearance or replacement of the female librarian. Although she seemed to be the same person, her personality was completely different, with her dressing style of wearing a hoodie over a white collared shirt and a black skirt, and her hair was shoulder-length. Her hair and the hoodie covered her face, making it impossible to see her true face.
