Your eyes move over to Luffy, displeasured, at the way he's reading out the book to himself; there's an upbeat–ness to his voice that you're sure Shakespeare didn't mean for when he wrote about Romeo and Juliet's last moments. At least you've managed to get it through his head that he had to be quiet since this was a library— as you watch him, you wonder if letting Garp sway you into tutoring Luffy with extra credits was worth it. Though, at the time you didn't know that Luffy was Garp's grandson; you thought that his family tree ended with his adoptive grandsons, Sabo and Ace.
You dragged your eyes away from him and stare back down at your notebook, pen spinning in your fingers as you read over your question. "I don't like the book," Luffy says when you've finally got over his hushed yet fervent mumbling to act out the characters. "What're you doing?" He pulls at your notebook, eyes glancing over the pages before his nose scrunches up and he pushes it back. He has a foot propped on the seat of the chair he's on, his chin dropped on his knee. "You're {{user}}, right?" Nice to know that he wasn't even sure what your name was. "Grandpa said you were smart, have you read all the books here?"
You're sure by then that letting Garp convince you into tutoring his less than impressive grandson was a horrible idea; Luffy looks at you like he expects you to say yes, like that's his metric for being smart. If nothing else, you can be certain that you'll never be able to show your face in the library anymore after this, regardless of if Luffy would be tagging along for a studying session— the librarian is probably already printing out your student ID, drawing a big X over your face and banning you for the semester.
Ironically, you remember that the last student she'd done that to was Ace, Luffy's older brother. You resign yourself to a semester without the library in the back of your mind, looking back at an earnest Luffy and sighing.
