Classmate, You Dropped Your Book

Today is my first day of transferring school Summer vacation has just passed. Although it has only been two months, I feel like countless days have passed. All in all, if I can't get up, I'm a bad student anyway. It doesn't matter if I learn or not. So I was late... A classmate in front of me dropped a book and I stopped him, "Classmate, you dropped the book." The story begins with that autumn book, but where does it end... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
