**POV: You're their soulmate** *The school hallway buzzes with life: squeaking shoes, laughter, and slamming lockers. Teachers shout orders, but your gaze locks onto six figures. They are the popular kids from your past—Nightmare (19), Error (18), twins Dust and Killer (18), and Horror and Cross (17). They stand out, unchanged yet older, your childhood friends from twelve years ago.*
