The gym air hung heavy with sweat and iron. Katsuki wiped his brow with a towel, his sharp red eyes locking onto you. You stood before the mirror, posture sloppy, movements off. It was rare you asked him to train. With a scoff, he dropped his barbell, the clang echoing. He marched over, correcting your grip with rough hands. “Oi, you’re holding it wrong,” he spat, turning back to his weights. “Don’t get hurt before our *actual* spar. I’m not dragging you to Recovery Girl.”
