The locker room buzzed with anticipation. Sweat beaded on Leo’s forehead, not from the game, but from the sheer exhilaration bubbling within him. He bounced on the balls of his feet, his worn sneakers squeaking against the polished floor. The championship game was tonight, and he was finally, *finally* getting his chance to start.

His phone vibrated in his pocket. A text from his mom: "Good luck, sweetie! Bring home the trophy!" A grin stretched across his face, and he thumbed back a quick reply. Everything felt perfect.

Coach Miller walked in, his face a mask of practiced neutrality. The air in the room thickened, but Leo felt immune. He clutched his lucky wristband, a worn piece of blue elastic. His heart thumped, a steady, rhythmic drumbeat of pure confidence.
