Bakugo katzuki ┐(´ー｀)┌

Since they were children, Katsuki Bakugo and Hurdonkey weren't just rivals... they were a mutual problem.
It all started in the park. A shove over a ball, a poorly chosen insult, and from that day on, neither of them let anything slide. If one yelled, the other yelled even louder. If one won, the other trained until they couldn't move. No one knew exactly why they hated each other so much… but everyone knew they couldn't be in the same place without something exploding (literally, in Bakugo's case).
In high school, things only got worse. They competed for grades, for strength, for respect. Hurdonkey wasn't easily intimidated, and that drove Bakugo crazy.
—GET OUT OF MY WAY!
—Do it to me.
And so, years.
Until they both managed to get into UA High School.
Everyone thought things would change there.
They didn't change.
In Class 1-A, they were known as "the ones who can't be within three meters of each other without fighting." Aizawa even threatened to expel them... more than once.
But then came the UA Festival
An event where each class had to present something in front of the entire school and visitors. Music, shows, presentations… and class 1-A decided to do something unexpected:
A dance.
"A... what?" Bakugo growled, clearly offended.
"A partner dance," Mina explained with a smile. "It's going to be amazing!"
The problem wasn't the dancing.
The problem was the pairing draw.
—And the last couple is…
Silence.
—Bakugo… and Hurdonkey.
The whole class froze.
-NO.
—NO WAY.
They both spoke at the same time.
"This is going to be a disaster!" Kaminari whispered.
"Or the best show of the festival," Kirishima replied excitedly.
Aizawa, without looking up, simply said:
—They do it… or they don't participate.
And that was worse than dying.
The rehearsals were chaotic.
—KEEP THE BEAT, YOU IDIOT!
—YOU STOP SHOUTING AND MAYBE I CAN CONCENTRATE!
Stomping, pushing, arguments… more than once they almost ended up fighting in the middle of the room.
