Opening scene

You blink, and the world snaps into focus. The faint scent of old books and polished wood hits you first. You're seated at a small study table in the far corner of Elysium University's central library — third floor, the quiet zone where almost no one ever comes unless they actually intend to work. Afternoon sunlight slants through tall windows, painting golden stripes across the pages of the mathematics textbook lying open in front of you. Your hands look... normal. Ordinary. Forgettable. Exactly like the rest of you is supposed to be. Then the air in front of your eyes shimmers, invisible to anyone else. **[SYSTEM INITIALIZATION COMPLETE]** **Welcome, Unnamed Variable.** **Current Designation:** Mob Character #47 **Relevance Points:** 3 / 100 *(Below 10 → increasing risk of narrative marginalization.

There she is. Akari Tanaka stands two tables away, clutching a thick spiral notebook to her chest like a shield. The classic first-year uniform clings in all the right innocent ways: pleated skirt just short enough to show the faintest suggestion of thigh when she shifts her weight, white blouse stretched slightly across modest but perfectly shaped breasts, navy ribbon tied neatly at her throat. Her long black hair is tied in a slightly messy low ponytail, a few strands framing cheeks already tinged pink from nervousness. She scans the room hesitantly, clearly looking for someone. You know who. *Hero normally sits at the big table near the window, waves her over with that easy smile, and the rest… becomes chapter one.* But today he’s late. Or maybe distracted. The timeline is already bending. Akari’s eyes finally land on you — the only other person in this secluded section. She freezes for a second, then gives a tiny, polite bow of her head, the kind Japanese students do when they’re not sure if they should speak. She takes one hesitant step closer. “Um… excuse me?” Her voice is soft, almost a whisper. “Are you… waiting for someone? Or… would it be okay if I sat here? The other tables are all taken downstairs and I really need to study for the calculus quiz tomorrow…” She bites her lower lip — an unconscious habit you recognize from the original pages. Your heart rate picks up. The System chimes quietly in your vision: **[Opportunity Detected]** Talking to her now will cost no Relevance but carries risk of social misstep. Current Charm 4 → base success chance low. Choose your opening words carefully. What do you say? (Or do you stay silent and let her make the next move?)
