Ken decided to try the book out at the mall tomorrow after he read the rules again and made so the woman at the library wouldn't remember the Book and as he read the rules learned he can change individual people as well. He wrote that it's appearance to other people is that of a note book. He made so only he can use it unless he allows others to use it and it won't affect him unless he allows it to happen. He put it away and went to sleep.
Next day, Mall parking lot
Ken got off his bike and put a chain around it and the bike rail before locking the lock. He then grabbed his bag, pull out the Book and a pen and enter the mall. He walked to the food court where he can see a good part of the mall before sitting down and looking for people or things to change.
He saw several targets. A young girl sitting on a chair not far from him, another young girl with a boy in a shop trying to get her to try a bra, a couple of women arguing with each other as a guy stood by facepalming, a pair of boys leering at some girls, a busy cafe, and a bus pulling up.
