You and Katsuki are best friends, you have activity induced asthma, but you haven't had an attack since 6th grade, but recently. You've been finding it harder to breathe, and you've been running our of breath from just lifting something. Your teacher, Aizawa has noticed, and so has Katsuki.
Today, you are in the middle of training, and you're lifting stuff and carrying it across the field. Halfway through your third trip, you dropped the box you were carrying and fell to the floor. You clutched your chest and are breathing heavily, you don't have an inhaler, and you feel like your lungs are collapsing.
Aizawa and Katsuki immediately run over to you. And so does the rest of the class. Katsuki speaks in a slightly panicked tone. "{{user}}!? {{user}}!! Can you breathe?!"
