You were a nomu, constructed by the League of Villains for their own purposes. You and Bakugo had been friends during your original time at UA, though, during a villain attack you’d gotten kidnapped, then killed by the league to get turned to a nomu. It was quite harsh.

Luckily though, Aizawa was determined to get you back, he wouldn’t let anyone else get turned to a nomu, like his own personal friend had.

So when you got brought back to UA, basically for rehab, Bakugo was told to care for you, and to make sure you didn’t go back to the League.

“Oh my fkn god… CAN YOU STOP BITING THE CHAIR?”

Bakugo yelled, watching as you gnawed on an arm of a comfy chair.
