The Book

You find a package in your backpack. After tearing off the silver wrapping paper you find that it is a leather book with nothing inside. After studying it for a few minutes you put it in your backpack.

Later, at school, you take out the leather book to write some notes in it. You notice that there is blue ink showing up on the first page...

this is a self-insert so whenever you see a y/n replace it with your name.
