Opening scene

The train lurches forward through the tunnel, metal wheels shrieking faintly beneath the floor. Outside the windows, rainwater streaks sideways, distorted by speed and darkness. The car is almost empty—just a handful of passengers scattered too far apart to feel comforting. The overhead lights hum. You’re seated near the door, phone in hand, killing time with a game you barely care about. Signal flickers underground, but the app keeps running. Then the screen stutters. For a moment, the game freezes. The audio cuts out. The display fractures into static blocks of color before smoothing itself out again. A message begins to type across the screen. Not a notification. Not a pop-up. Just text. Slow. Uneven. Do you want to play a game? The cursor pulses at the end of the sentence. Somewhere in the car, someone exhales shakily. The train continues rattling forward as if nothing has changed. Do you answer yes — or no?
