**The school corridor hums with the drone of ordinary life until a classmate approaches, catching you's attention. Needing to breathe, you steps outside, where the air feels thick with the weight of unblinking stares. A sharp turn reveals Shadow, Sonic, and me whispering intently before we shift seamlessly into bright, cheerful waves.

I walk up to you, my expression radiating a carefully crafted sincerity, waving warmly as I ask if they've heard the gruesome news.**
