The common area was chaos. Pillows, blankets, and snacks were spread out everywhere, Class 2A buzzing with chatter and laughter. Mina and Denki had somehow convinced everyone to have a full-class sleepover, and even Katsuki—after much grumbling—showed up, plopping down on the couch with his bag of chips.

You walked out of the elevator last, arms full of snacks you’d brought from your room. Everyone immediately noticed—mostly because Mina squealed.

“NO WAY—LOOK AT YOU TWO!” she shrieked, pointing between you and Katsuki.

You blinked, confused, until you followed her finger and looked down. You were wearing your red-and-blue Spider-Man pajama pants… and Katsuki, sitting cross-legged on the couch, was in black-and-yellow Batman pajama pants.

For a second, the common room went dead silent. Then it erupted.

“Oh my god, they MATCH!” Denki howled, clutching his stomach.

“They’re like—opposite but matching couples pajamas!” Mina gasped dramatically.

Eijirou slapped Katsuki on the back, laughing. “Bro, I didn’t know you were the type to coordinate!”

Katsuki's face immediately flushed crimson. “TCH—WHAT THE HELL ARE YOU TALKIN’ ABOUT?! I just grabbed pants! What the hell’s it got to do with them?!”

You were already hiding your face in your sleeve, laughing. “I swear I didn’t plan this! I didn’t even know you owned those!”

“That’s ‘cause it’s none of your damn business!” he barked, though the way his ears were burning only fueled everyone’s teasing.

“Aw, it’s fate,” Mina cooed, clasping her hands dramatically. “Batman and Spider-Man, united at last!”

“Don’t they come from different universes?” Izuku mumbled off to the side, but nobody was listening.

You groaned, dropping onto the beanbag chair next to Katsuki while the whole class carried on with their teasing. He glared around the room like he might explode if they didn’t shut up, but you leaned toward him with a small grin.

“…At least we both have good taste,” you whispered.

For a split second, he froze—then he clicked his tongue, looking away with a sharp scoff. “Hah. Damn right we do.”

And of course, Mina caught the whole exchange on camera.
