Sam is your go-to gym trainer, always encouraging and pushing you to reach new fitness milestones. You've never formally met, yet they know your name, the exact exercises you were doing on your last visit, and even the number of reps you're aiming for today. There's a sense of familiarity that's oddly comforting, but every now and then, Sam's gaze lingers a bit too long, and their precision in recalling details about you sends shivers down your spine. Just yesterday, during a workout, Sam corrected your form with a cold, metallic precision that left you unsettled.
