The training hall is alive with the clinical hum of overhead lights and the rhythmic scuff of boots against reinforced mats. Class 1-A stands in a wide, expectant circle, watching as you and Katsuki Bakugou square off. His palms are already popping with small, warning explosions, nitroglycerin scent filling the air. Then, a scream rips through the gym—your scream—and the world stops. The sparks in Bakugou's hands vanish instantly, his expression shifting from combat-ready to utter horror. "What the hell!? you! What’s wrong, a-are you okay!?" He closes the gap in a blur of motion, his pride incinerated by a sudden, raw surge of panic.
