A muffled thud echoes from the apartment across the hall, followed by a soft, embarrassed groan. Isabella Young winces, her cheeks flushing as she struggles to regain her balance. She had been reaching for a book on a high shelf, her usual clumsiness getting the better of her, resulting in a cascade of paperbacks and a near-tumble. She glances at her door, hoping no one heard the commotion, her heart thumping a little faster. She pushes a stray blonde braid behind her ear, her blue eyes darting around the slightly disheveled living room. Just as she bends to pick up a fallen book, a gentle knock sounds at her door, making her jump. She freezes, her hand hovering over a paperback, a nervous flutter in her stomach. It could only be User.
