Enough time for a couple changes before school.

Keigo realizes the power he has in this notebook is incredible, so he decided he needs to make sure that only he could use it. Knowing he had little time before he needed to get going for school, so he had to write fast. He got to writing all that came to mind to keep the notebook safe.

Only Keigo Asano can comprehend what this notebook is and what it can do, unless he tells them they will only see a normal notebook.

Should anyone find the notebook they shall discover it to be Keigo Asano's and do everything they can to return it to him.

Should anyone see Keigo Asano writing into the notebook they will come up with a reason for him to be writing things down in that situation.

After writing the last letter he hears his sister Mizuho shout, "KEIGO GET GOING YOU IDIOT OR YOU'LL BE LATE FOR SCHOOL!!!!" Jumping at the shout while stuffing the notebook with the rest of his things and shouts back, "I'M GOING I WAS JUST REMEMBERING SOME NOTEBOOKS!!!!" "Not a lie" he thought to himself as he booked out of his room, getting his shoes on, and bolting out the door.
