The Only One Who Didn't Know

Summary:

I mean, if it walks like a boyfriend and explodes like a boyfriend…"

Chapter Text

It was a rare sunny afternoon at U.A., the perfect weather for the annual Parents' and Mentors' Open Day. Students walking around with their families, showing off the campus and bragging about their quirks improvement. Class 1-A’s dorms had never been so lively.
Katsuki Bakugou stood by the snack table, aggressively stuffing his face with spicy rice crackers while pretending not to care about anything.
"Oi, Izuku, stop hovering near my mom!" Katsuki barked, glaring across the room.
"Y-Yes! Sorry, Kacchan!" Midoriya squeaked, scurrying away from Mitsuki Bakugou, who was currently interrogating Kaminari about his hair dye choices.
"Jeez, you’re just like your old man," Mitsuki grumbled, rolling her eyes before perking up when she spotted a cheerful brunette bouncing over.
"Hi, Mrs. Bakugou!" Ochako chirped. "And you must be Mr. Bakugou, it’s so nice to meet you both!"
Masaru gave a small wave, visibly relieved to be acknowledged in peace while Mitsuki grinned wide.
"So you’re Ochako, huh?" Mitsuki smirked, giving her an appraising look. "Katsuki talks about you all the time."
Ochako blinked. "He does?"
"Yeah, it’s 'Uraraka did this,' 'Uraraka beat that villain,' 'Uraraka’s gravity quirk is better than half these damn extras,' 'Uraraka's the only one who's not a complete idiot.' Honestly, it’s exhausting."
Ochako flushed pink. "Really?"
"Yeah!" Mitsuki leaned in conspiratorially. "So, when are you two finally gonna get together?"
Ochako snorted, waving her hands. "Oh, we already are. He just doesn’t know it yet."
A loud choking sound came from behind them.
Katsuki, mid-bite of another rice cracker, stood frozen. "WHAT THE HELL DID YOU JUST SAY?!"
Ochako blinked innocently. "What? It’s true."
"Like HELL it is!" he snapped, face going bright red.
At that moment, the rest of Class 1-A materialized like vultures sensing drama.
"Oh no, Bakugou, she’s right," Kaminari grinned. "We’ve all basically considered you two a thing for months."
"Yeah, dude," Kirishima laughed, slapping his shoulder. "You're literally the only one who didn’t notice."
"Honestly, it was getting awkward," Mina added, sipping her drink. "Especially when you dragged her to train alone like, four times a week."
"Totally dating energy," Jirou deadpanned.
Even Todoroki chimed in. "I assumed it was a public secret."
Bakugou’s eye twitched. "THE HELL IT IS! I’D KNOW IF I WAS DATING HER!"
Ochako gave him a smug, lopsided grin. "Would you though? 'Cause you sure act like my boyfriend. Carrying my stuff, waiting for me after class, threatening anyone who flirts with me… I mean, if it walks like a boyfriend and explodes like a boyfriend…"
Katsuki spluttered, mouth opening and closing uselessly.
Masaru Bakugou chuckled. "Son, you might wanna catch up."
Mitsuki grinned smugly, arms crossed. "Told ya he’s dense."
Katsuki glared at all of them before fixing Ochako with a flustered scowl. "You—! Damn it, Round Face…"
Ochako just reached out, grabbing his hand with a victorious grin. "Welcome to the relationship, Katsuki."
And to everyone’s absolute delight — and several people’s need to discreetly record it — Bakugou Katsuki didn’t let go.

Later that evening…

The dorm common room was quieter now, most parents having left, and Katsuki still hadn’t quite recovered. He sat slouched on the couch, arms crossed, scowling at the TV like it had personally wronged him.

Ochako plopped down beside him, grinning.

"You good there, boyfriend?"

He groaned, covering his face with one hand. "I swear to god, Round Face…"

She leaned in close, teasing. "You gonna deny it? C’mon, even Todoroki figured it out before you."

"Tch," he clicked his tongue, glaring at her sideways. "How the hell was I supposed to know you felt that way?"

Ochako raised a brow. "Because I flirt with you constantly."

"You’re bad at it!"

"I called you babe last week!"

He coughed violently, ears burning. "I thought you were being a little shit!"

Ochako giggled, leaning her head against his shoulder. "Yeah… but I meant it too."

For a moment, neither of them spoke. Katsuki sighed, tugging his hand through his hair, eyes darting anywhere but at her.

"So… you serious?"

She grinned softly. "Dead serious."

Another beat. Then, Katsuki reached out and hooked his pinky with hers.

"Guess I’m yours now then."

Ochako beamed so hard it felt like her cheeks would split. "Good. Took you long enough."

Meanwhile, in the Class 1-A group chat:

[Group Chat: 1-A CHAOS SQUAD]

Kaminari: GUYS GUYS GUYS
THEY’RE DATING FOR REAL NOW

Mina: OMG did it happen?? Did she finally corner him??

Kirishima: Did he explode something when she told him?

Jirou: Did he pass out?

Midoriya: I’m so happy for them… but also scared for my life if Kacchan finds out we’re talking about it.

Todoroki: I’d rate the confession 6/10. It lacked dramatic background music.

Yaoyorozu: Should we… throw them a party?

Kaminari: YES. Bakusquad style.

Mina: You KNOW he’ll yell at us.

Kirishima: He’ll yell anyway. Might as well earn it.

Ochako:
just sent a selfie of her and Katsuki watching a movie, his arm around her shoulders, both smirking smugly

Ochako: Too late, suckers.

Bakugou: [Left the chat.]

Kaminari: AHAHAHA LEGEND

Mina: It’s happeningggg

Todoroki: I'll bring soba.
