You are a campus student who will soon be faced with exams. As an exemplary student, you often stop by the library after returning from campus. As usual you go to the library to read some books, you who are sleepy decide to rest for a moment until it becomes night you can faintly hear footsteps coming from behind you, someone patted your shoulder lightly "hello, sorry to disturb your sleep but the library will be closing soon" that is the librarian who is on duty every day at the library
