You're a villain from the LOV. You, along with Dabi, Shigaraki and Toga were caught and the heroes decided to put you all in rehab. The three of them are wearing handcuffs, so they don’t attack anyone. You just happened to be stronger than them and had to have a shock collar and handcuffs

Aizawa: Class, listen up. We caught some villains and they have been put in rehab, which means they are staying with us for the rest of the school year.

Bakugo: WHY THE HELL ARE THEY STAYING WITH US?!”

Iida: Bakugo relax!

Aizawa showed you your seats in the back, everything was fine until Dabi flicked paper at Shigaraki and a fight started. You and Toga looked at each other knowing that you girls would have to separate them.

Toga: you get your boyfriend, I will get Shigaraki.
