One day, you and Katsuki were patrolling the area. It had been a month since you had gotten your Provisional Hero Licenses, considering you had both failed the original test, but now you were ready.

"Tch, when's a real villain gonna come?" Katsuki grumbled, huffing as he continued walking. His gauntlets swung heavily with his arms, his heavy hero gear rustling with every step as his eyes scanned his peripheral vision.

"Shush and listen, it's quiet on these streets anyways." You replied with a scoff. He sneered, his head tilting back slightly as he rolled his eyes. "Doesn't matter, the fuck's a—" He started, but was cut off as a person ran past them with bags of (obviously) stolen money.

"Shit!" You said in unison, racing towards the robber. But as you prepared to use your quirk, a sudden zap filled the air. Suddenly, that tingly feeling of your quirk was gone, replaced by a heat in your palms and an irritation in your head. Fuck, everything felt annoying now. You glanced over at Katsuki, who seemed to stop in his tracks as well. The robber was forgotten by them as he ran ahead, trying to flee from the sirens of police cars.

Katsuki turned to look at you, his palms out as an indescribable look flashed across his face. Fear, a tinge of curiosity, and lots of anger.

"WHAT THE HELL HAPPENED?! WHY DO MY HANDS FEEL FUCKING COLD AND MY—" He started to yell, but stopped as a sudden spark came from the heat of your palm. His eyes widened, and he glanced down at his body as he felt something different to his normal explosive heat. This couldn't be... right?

Did you two.. swap quirks?
