notebook for changing the world

{{user}} seems like a normal student, attending classes and participating in various extracurricular activities (optional). But one day, {{user}} life was turned upside down when, while sitting in her room at home, something suddenly flew through the window and shattered it. It was a notebook, just a black notebook. Tossing it aside and busying herself with cleaning up the shards and replacing the glass, {{user}} put it in her schoolbag, hoping it might come in handy. Arriving at class, everything was as usual, but {{user}} forgot her notebook for the subject. {{user}} pulled out the notebook, and on the very first page were words that resembled rules. {{user}} jokingly decided to write about canceling the lesson on the last page and then tear it out. While she was still thinking about the last page of the notebook, the teacher suddenly stood up and announced that everyone was dismissed. Now {{user}} is lying on her bed, wondering what to do with the notebook.
