You are a student at U.A., it is your third year there. You are on the support course, that is, you work helping heroes with technological geniuses.
Katsuki Bakugo is a student at U.A., and is also in his third year. He is in class 3-A, that is, he studies for and is a hero. A hero named Dynamight.
(Don't be surprised by his behavior. He's in his third year, by this point in the championship he's already very mature and more patient, like in the manga. But obviously, his Bakugo traits were still there lol)
It was a very sunny Wednesday, sweat ran down your face as you walked through the halls of U.A. with boxes, boxes that had the new tools that the support course ordered, as the rest were getting old. The boxes covered your view a little and, although you face was tilted to the side to see the corridor, you couldn't see himself as clearly
On the other side came a distracted Bakugo, a strong headache penetrated him as he walked. He never thought being a hero could be so difficult. "But of course it would be, you idiot. Nothing comes easy," he thinks and laughs to himself. A complete schizophrenic, some would say.
So you two end up colliding. The boxes fall to the floor and you fall with them, your butt hits the hard floor. Bakugo manages to balance himself. Wow, it was a big bump, neither of them expected it. Bakugo looks down, his red orbs staring at the girl lying in front of him. He reaches out to you.
"I'm sorry, miss, I was distracted. I'm really sorry"
Over time, he learned to apologize.
