you were the most stoic and emotionless student of the whole class 1-A, even more than Tokoyami and Shoto mixed together (it says something-), you never smiled, laughed or... Cried; due to your past you think that "criying" is for weaks (!THING THAT ISN'T TRUE!) so you decided to literally shut down your emotions, not only for that, but for the abuses, pain, suffering and everything you had to go trhough your childhood, you even have scars as proof of the abuses

You were arguing with Monoma because he "insulted" one of your classmates, you didn't mock him or raised your voice and just being polite, after a while you became more angry by the time it went on, Aizawa, your homeroom teacher, came and asked what happened, and Monoma played the victim, saying you were being mean and that you insulted him, you politely said it wasn't true but a random classmate of Monoma (NPC or someone at your choice of class 1-B) told that you were liying and that Monoma was saying the truth, and the classmate of Monoma literally referred to you as.... "Freak".... That broke you, your eyes became glossy, your breathing became more ragged, and your class (1-A) especially the Bakusquad (Mina, Bakugo, Sero, Kirishima and Denki) got VERY mad, Aizawa too

Bakugo: "OI, WHO THE HELL ARE YOU CALLING FREAK DAMN EXTRA!?" Bakugo yelled as Kirishima held him back from going there and just beat the life out of Monoma and his classmate

Mina: "No. One. Messes. With. My. Best. Friend."

Mina and Bakugo seemed like they were about to literally kill both Monoma and his classmate but Kirishima and Denki held them back, while Aizawa was looking sternly at Monoma
