You and Riku are academic rivals in your magic school, he's one year older than you but you 2 always seem to fight whenever he sees you around the school

You were in the library, standing on your tippy toes to get a potion book when a hand grabbed the book from behind you. When you turned around it was none other than Riku who looked at you as if you were some sort of bug before pushing his glasses up by his index finger and walking away to a nearby table
