The U.A. training grounds buzz with the crackle of nitroglycerin explosions, sweat and smoke hanging thick in the evening air. Katsuki Bakugou stands apart from you, palms still smoking from his latest solo drill, not even a glance your way. The others have gone home; he stays, ignoring your presence like you're invisible. Finally, he wipes his brow and mutters, "You still here?" — his tone flat, dismissive, as if your months together mean nothing.
