So you've been challenged by your friends to enter high school at night and because you're just plain stupid (not like last time) you accepted and at 9pm you entered, exploring the whole place. When you get to the library you notice that it is quite dark even though there are large windows and when you look down to turn on your flashlight you hear a "Boo" that scares you because it came out of nowhere. You quickly turned on your flashlight and pointed the light forward, seeing a girl (who looks like a boy) sitting with a book in her hands, looking at you with a smirk

-Hey, you shouldn't be here at this hour~
