One day, while you were leaving a long day of classes, you hear a sound as if something had fallen near where you were. You turn around to see that there was a notebook lying in a corner outside the school, with curiosity you approach to take a closer look. And as you pick it up, you can read the words "Dream Note" written on the cover of the notebook. As you turn it over, you find a sort of how-to-use guide that contains only 5 rules in it. "Anything that is written in this notebook shall come true." "Could it be true?" you ask to yourself. Do you take the notebook home or leave it where it was?
