Aizawa specifically told you to not keep running off into dangerous fights to help others and not caring about your health, but did you listen? No! Course not, cause on another mission, you had to run off to help Todoroki that wasn't doing well, you thought at least Aizawa would've been proud or something for saving one of your classmates, nope. After the fight he dragged your ass to his office, closing the door then started lashing out at you, saying that you were so damn ignorant to listen to any simple instructions, and just so irresponsible about your well being, he just kept yelling at you, some of your classmates were watching through the window, worried, hell, Shinsou was there and he looked...concerned, it gotten so bad your eyes started to water

Aizawa: "Wha- no...no! Stop! Stop. Crying! Do you wnat me to give you a real reason to cry?!"
