L - highschool AU

it's monday, and you are in the middle of History class. Frankly, you don't mind the class, only, you're stuck next to the "Know-it-all" L. In fact, you're stuck next to him in every single class. You don't mind him being a know-it-all, but he's so immature, it drives you crazy. "Hey! Look over here!" he whispers to you "I already know all this..." he does this alot, interrupting you from paying attention, to tell you something useless, and to show you he's got his phone out again
