TodoBakuDeku one-shot, Boku No Hero Academia)

The Big Three.

And no, I don't mean Mirio, Nejire, and Tamaki.

You see, the students of Class 1-A are now the students of Class 3-A, and a certain trio among them, have taken the title of The Big 3.

Shoto Todoroki, Katsuki Bakugo, and Izuku Midoriya. Otherwise known to UA, as the New Big Three.

People have heard and seen how close the trio are, and some even rumor that they're dating.

"Alright, since you all seem to be so worried about internships, why don't I get some third years to come down, and explain what it was like when they had their internships." Shota Aizawa, the teacher of the current Class 1-A, stares menacingly at his students, who had all been panicking at the thought of interning with real pros.

All of them nodded at once, and Aizawa sighs. He grabs the classroom, phone before dialing a certain classroom.

"Send three of Class 3-A's students to Class 1-A please." he says, "Sure those three will work. Tell them that we're talking about internships."

He hangs up.

Meanwhile, in Class 3-A, Ochaco Uraraka had just gotten off the phone for their teacher, who was using the washroom.

"Hey, Deku, Bakugo, Todoroki! Mr Aizawa wants you to go to his class, it's about your internships from First-Year." She exclaims excitedly.

"Us?" Izuku, otherwise known to his friends as Deku, tilts his head.

"Isn't he teaching?" Shoto asks.

"Whatever, what about our class?" Katsuki demands.

"We'll let our teacher know where you went." Tsuyu Asui promises, "Just head down before Mr Aizawa gets mad."

They would've protested, but the mention of their former teacher being angry at them...

It didn't sit well, let's say.

So the three of them got up, and left the classroom, heading downstairs to Classroom 1-A.

"Now, I have three students coming down to talk to you. Third-Years from Class 3-A. You might know them as the New Big Three." Aizawa explains to his class, just as a knock sounds on the door.

Murmurs spread throughout the room, of excitement, nervousness, and confusion.

Aizawa opens the door, and a trio of students come in.

The New Big Three, or the trio of Shoto Todoroki, Katsuki Bakugo, and Izuku Midoriya.

"Hey Mr Aizawa, we we're told you wanted to see us?" Izuku asks.

"Yes, I want you to explain what interning is like to my class, since they seem to be panicking. You three interned as first years as well, so explain." Aizawa orders, before laying down in his sleeping bag, and attempting to nap.

The class stares at them, and they stare at the class.

Minutes of silence pass.

"I... can't do this..." Shoto mumbles, his shyness starting to get the best of him.

"Don't worry Shoto, remember how much fun internship was?" Izuku asks.

"No." Katsuki retorts.

"So, your the New Big Three?" A student from the back calls.

"Huh? Uh, yep! I guess you could say that!" Izuku says.

"Mr Aizawa said you interned as First Years too, can you tell us what it was like?" Another asks.

"Well-"

"It was stupid." Katsuki says.

"Of course you would think that, you came back with a much needed hair cut." Shoto retorts.

"WILL YOU SHUT UP ABOUT THAT STUPID FLAT HAIR ICYHOT?!" Katsuki yells in return.

"Guys, come on, don't fight!" Izuku quickly gets between them, holding his hands out.

Katsuki growled, but backed down, and Shoto didn't react.

"Can, we know what it's like?" A student asks.

"Well, interning was different for all of us. Katsuki didn't enjoy it, because he made a bad choice as to who he interned with. I'm sure you don't have to worry about that though." Izuku says, smiling, "For me, it was all about learning to use my quirk without hurting myself, because at the time, I couldn't use it without breaking my bones."

"You still break your bones dumbass." Katsuki retorts.

"Language Katsuki." Shoto scolds.

"Tch, don't tell me what to do." Katsuki grumbles.

"Well, Shoto enjoyed his internship, didn't you?" Izuku asks.

"No. I interned with my father, and we both almost died..." The last part was said quietly, so nobody heard except Izuku.

None of the first years looked any better about interning, in fact some of them looked worse.

"Okay this isn't working, we need to try something else." Izuku mutters.

Suddenly, from the back of the class..

"I SAID SHUT UP!" A girl, with a braid of blond hair, dyed red at the ends, yells at the girl next to her.

"Meep! Sorry Ella~chan!" The girl next to her, with a black mop of hair, squeaks while almost falling out of her chair. The blond girl turns away grumbling.

"Hey, don't fight in front of the Third-Years you two!" A boy with blue hair and glasses, baring a striking resemblance to the Third-Years classmate, Tenya Iida, stands up and hits the two girls.

"YOU WANNA FIGHT ME?!" The girl stands up, glaring at the boy.

"NO I WANT YOU TO CALM DOWN!" The boy yells.

"H-hey, come on Ella~chan, Iida, w-we don't need to get violent!" The black haired girl timidly tries to calm them.

"SHUT UP OROKA!" The blond yells, whacking her.

"O-ow!" The black haired girl shrinks away, as Izuku, Shoto, and Katsuki stare at them.

"Guys, the Third-Years are staring..." The black haired girl mumbles timidly.

Silence passed, before Katsuki unexpectedly burst out laughing.

"Kacchan?" Izuku asks, confused.

"Those two remind me of me and you, back when we we're first years!" Katsuki laughs, pointing at the two girls.

"Hm... your right, and the boy... you called him Iida, correct? You don't happen to be a younger brother of Tenya Iida, do you?" Shoto asks.

"Yes, he's my older brother. I heard he was in your class." The boy says.

"H-how do we remind you... o-of you?" the black haired girl asks.

"When we we're First Years, Kacchan and I acted a lot like you did. Kacchan was always yelling and hitting me." Izuku explains.

"Hey, I don't anymore!" Katsuki retorts.

"Yeah, but you had serious anger issues. Just like that blond girl." Izuku replies.

"I DO NOT HAVE ANGER ISSUES! AND I DO HAVE A NAME!" The blond yells.

"She has anger issues." The ravenette mumbles.

"Kacchan also called me Deku, like the blond called you Oroka." Izuku says, though the girl whimpered at her nickname.

"Oroka... that means 'stupid', like how you called Izuku, 'Deku', because it means 'worthless nerd'." Shoto says.

"What are you trying to say?" Iida Jr. asks.

"I think... you guys are a lot our class, but more worried. You don't have to worry about internships though," Izuku says, "because almost everyone in our class loved them, even if a handful of us had trouble."

Nobody looked any better.

"Hmm... it seems.. like the problem isn't the internships themselves," Shoto says, "but the fact that you'll be trained by real pros. Are you worried about judgement?"

To some surprise, the class nods and murmurs in agreement.

"If your worried about being judged for not being strong enough..." Izuku mutters to himself, before getting an idea.

"You can all fight Shoto!"

Silence.

"I... what?" Shoto asks.

"What he said." Katsuki mutters.

"Well, they're self conscious about being judged for lack of strength, right? So fighting would be good training!" Izuku exclaims.

"I can't believe, you of all people thought of that." Katsuki says.

"I'm surprised you didn't." Izuku retorts.

"Is... this okay?" One of the students asks Aizawa.

"Do whatever, just don't get hurt too badly." Aizawa replies tiredly.

"Figures..." Shoto mumbles.

"To the gym!" Izuku cheers, marching out of the classroom, with his two boyfriends and the students behind him.

The gym was empty, thankfully for all of them.

"I didn't agree to this..." Shoto mutters.

"Relax Shoto, you'll be fine! You of all people know how to hold back!" Izuku exclaims.

"Hey First Years, do me a favor and beat Icyhot." Katsuki says to the students, who all look at him blankly.

"Kacchan, your supposed to be supportive of Shoto!" Izuku hisses.

"That doesn't mean I wouldn't like to see a bunch of newbies kick his ass." The ash-blond replies, smirking.

"Thanks for the vote of confidence Babe." Shoto sighs, before standing across the gym from everyone.

"Are you sure about this?" Iida Jr. asks.

"Yep! Don't worry about it, just think of it as extra training!" Izuku says cheerfully, before climbing onto Katsuki's back, who grunted but didn't dump him off.

The students nervously faced Shoto, who exhaled deeply.

"For your sake, I'll avoid using my flames."

"Push over!" Katsuki calls.

"Kacchan, shush!" Izuku exclaims, before yawning.

"Tired already?"

"I was up late studying..."

"Of course you were."

"Can I nap on you?"

"Tch, fine... I'm waking you up when we head back to class though."

"Thanks... Kacchan... zzz..."

"...damn you, you lovable nerd..."

As Todoroki sparred with the students, the explosive ash-blond remembered how all of this had happened.

At the beginning of their second year, one afternoon, when school had ended.

Two notes in all three lockers.

Outside the school.

"T-Todoroki? K-Kacchan??"

"Icyhot? Deku?"

"Midoriya, Bakugo?"

They all wanted to talk to each other.

"Let's all say what we wanted to talk about at once."

"Tch, fine."

"Alright."

And as each silently counted to three, faces growing redder by the minute, they all said the same thing.

"I think I'm in love with you both!"

Then they all stared, blushing madly, in complete shock.

"W-wait, but-"

"Are you kidding me?! How the hell can you both like me back?! I've been an asshole! Especially to you, Midoriya..."

"K-Kacchan, w-wait-"

"Shut up!"

"Bakugo, calm down."

"I... ugh... sorry..."

"I... don't know what to say... I-I don't get how either of you like me, I mean, I'm just a nerd, and I-"

"Tch, don't you dare start repeating all the shit I've said to you."

"Sorry..."

"...Let's give it a try."

"Huh?"

"Well, we just confessed, didn't we? So, let's give it a try."

"I... yeah, I guess your right."

"O-Okay, Todoroki-"

"Shoto."

"Huh?"

"Call me Shoto... I... prefer it to my last name."

"...In that case, call me Katsuki."

"Th-then, you can call me Izuku, if you want, o-or not..."

"Hug?"

"...fine."

"Okay!"

And that was the beginning of their relationship.

They tried to hide the fact that the trio were dating from their classmates, but it didn't take long for them to notice how Katsuki had softened up to them.

And then... well, they kind of got cornered by their friends...

and Shoto's siblings.

Katsuki watched the fight, while carrying a sleeping Izuku.

Finally, one of them, a girl with pale green hair, snuck up behind Shoto, and pinned him down. The students won.

"Hah!" Katsuki burst out laughing at Shoto's expression, waking up Izuku. Shoto glared at him.

"Huh?..." Izuku mumbles sleepily.

"Oops, sorry Izu." Katsuki apologizes.

"No... it's fine... did Shoto win?..." the green haired boy rubs his eyes, sliding off of Katsuki's back.

"Nah, that's why I was laughing."

"Heh... your mean..." Izuku mumbles.

"Get off me." Shoto growls, pushing the girl off him.

The girl says nothing, just stands up, and walks away.

"G-good job Ketzuka!" The black haired girl from before calls.

"...Thanks. You did well too Okati."

"Pfft, she snuck up behind him, that's a cheap move." The blond retorts.

"It may have been cheap, but it worked Iskanu." She says, standing up properly and dusting himself off, "Can we go now?"

"What, you don't wanna stick around?" A kid asks

"No, not particularly." Shoto replies.

"We have to get back to class anyway." Izuku says, "I hope you all feel better about interning!"

The kids nodded, and said goodbye, as the trio walked back to their class.
