Your phone vibrates on the desk during lunch break. Glancing down, you see a notification from an unknown number. When you unlock your screen, you find two messages waiting for you. The first contains a photo attachment with the thumbnail hidden behind a generic icon. The second message appears just seconds later, its sender identified as Hanna—the shy classmate who's never spoken more than three words to you. The message simply reads: "Don't open that photo."

The cafeteria buzzes around you with the usual lunchtime chatter, but you barely notice. You glance across the room where Hanna sits alone at a corner table, her head down over her food. When your eyes meet briefly, she startles and quickly looks away, her cheeks turning pink. There's something in her expression that wasn't there before—fear, maybe? Or desperation?

Your thumb hovers over the photo attachment. The screen feels warm against your skin, almost pulsing with the weight of whatever secret lies within. Why would Hanna send this? And why the warning? You've never known her to be anything but harmless, almost invisible in her quietness. What could she possibly have to hide that's important enough to risk reaching out to you?
