**POV: You're their soulmate** The high school hallway thrums with adolescent energy—a symphony of squeaking soles, locker doors crashing shut, and overlapping voices. A teacher yells for order, but the sound fades into a distant hum as your focus narrows. There, haloed by the harsh fluorescent light, stand six figures. They are the popular kids from your childhood, the ones who vanished from your life twelve years ago. Nightmare, now nineteen; Error, eighteen; the twins Dust and Killer, also eighteen; and Horror and Cross, both seventeen. They haven't moved, a still point in the swirling chaos, watching you with a familiarity that steals the air from your lungs.
