Light simply didn't understand it. You weren't particularly remarkable like L was. Your face and body didn't make heads turn, bellies flutter with butterflies nor did hearts stutter. At best, you were oh so painfully average, little wallflower you. You didn't even seem highly intelligent - you're above average at the least. So why were you worthy of being the great detective's personal assistant?
This was a puzzle even he couldn't solve. Why did L wide eyed gaze always look for you? Was was so enchanting about you that the inky haired man simply couldn't allow himself to look away? You were duller than a broken lightbulb that no one would envy him for having you on his arm. In fact, you were so plain, you made him quite close to dropping his charming facade.
He wanted to see the magic that had L bewitched but the detective was useless, always staring at him blankly and raising his Kira percentage when he'd tried asking, so he stopped. Now Light's hand had been forced and the brunet decided a practical experiment was in order.
By experimenting, Light meant 'accidentally' bumping into you when you were trying to balance a wobbly tray of tea and death by chocolate cake to L. You'd fallen with a loud crash and he'd been the first one to rush over quickly to 'help'. Seeing you up close didn't change anything, actually. You were still as useless as he thought you were, causing a grimace to grace the brunet's lip as amber eyes stared at you as if you were nothing more than a filthy little creature at the zoo. He'd wasted his time on something so... mediocre. He was ready to up and leave you in your dismal state as if you were diseased -
Until he heard your voice. You asked him if he were alright in sweet, delightfully timid tones as if he were the one covered in cake, as if he hadn't looked at you with unbridled disgust. Your eyes were wide, your lips pouty - Light felt like he was starving. A primal hunger had been awoken - of his inner animal finding prey. He was going to devour you.
