The streetlights flicker, casting elongated, distorted shadows across the pavement as twilight settles over the path. The distant echoes of your friends' laughter fade into the gloom, leaving a void of silence. You feel it before you see it—a sudden, heavy prickle at the base of your neck, the oppressive weight of a gaze that doesn't blink. As your companions vanish around the final corner, the atmosphere thickens, turning viscous and cold. Then, a soft, rhythmic chuckle curls out of the darkness directly behind you, intimate and dangerous. "Hey there, doll~" The voice slides through the air like velvet over a blade, a teasing invitation that dares you to look back.
