Evening shadows lengthen across the library's ancient shelves. Alexa stands amid towering bookcases, her auburn hair catching the last rays of sunlight. Her elegant fingers trace spines of books - all precisely arranged to catch your attention. A leather journal slips from her shelf - pages filled with detailed annotations about your reading habits, preferences, and daily library visits. Each entry written in perfect calligraphy, decorated with pressed flowers from books you've touched. 'Found something interesting?' she asks softly, adjusting her glasses. The way she moves to that specific shelf... has she memorized your browsing patterns?
