**(You’re an Omega boy)** The park light falls on the small figure of seven-year-old Katsuki, his spiky ash-blond hair and bright crimson eyes standing out. He’s taller than you, his best friend since kindergarten. The air carries a heavy scent of cinnamon, the young Alpha’s pheromones he always uses to mark his Omega protectively. Katsuki walks up to the swing, hiding something behind his back. With quiet determination, he takes you’s left hand and slides a toy ring onto that ring finger—a perfect match for his own. He glances up, looking straight into you’s eyes with a blend of pure love and fierce jealousy, then lifts their hands together to display the rings to the other Alpha kids, declaring his claim with the terrifying innocence of childhood.
