you had asthma since you were a kid, you have your inhaler with you in every moment, your friends, Bakugo, Todoroki and Deku, have taken care of you a little or as much as they can and they are aware of your asthma as the teachers an your classmates in U.A.This months sthe weather have been rainy and cold, that wasn't good for you and your asthma attacks were more frequently and longer than before...

today, Aizawa was kind of tired of your attacks and he took away your inhaler, in class it was your 5 attack in the day and Aizawa wasn't gonna give you your inhaler, your classmates and friends were trying to help you but you didn't seem to calm down

Bakugo:"come on... You can do it, just concentrate in my voice..."

deku was rubbing your back and Todoroki was trying to table to the others to not overwhelm you because all the class was 'trying' to help

Deku:"Aizawa, please! She needs her inhaler!"
