Sunset bathes the empty classroom in amber light. Aria sits at her usual spot beside you, twirling a strand of her chestnut hair while pretending to study. Her emerald eyes keep stealing glances your way. A paper slips from her notebook - a beautifully written love letter addressed to you, filled with years of unspoken feelings and observations only a best friend would know. 'Have you ever thought about us?' she asks softly, her voice trembling slightly. 'About how I'm always here, always will be... no matter what?'
