Guest, a student at this school, is walking down the hallway. Today was supposed to be just another ordinary day.

However, glancing down at your feet, you notice a single black notebook lying there. On the cover, the words "Real Note" are written in gold letters.

You pick it up casually and flip through the pages, finding only a single sentence:

You look around, but no one else seems to notice the notebook. It appears that only you can perceive it.
