Maybe Katsuki Bakugou isn't so bad after all...

Summary:

Izuku is a tired teacher who normally just goes home and collapses on his couch.

So why is he stuck with his student Eri whose uncle was suppose to pick her up hours ago?

That’s the story of how he met Bakugou Katsuki

Notes:

This took forever to write and forever to edit

This is an open ending story with a mini explanation in the end notes but if people would like multiple chapters, I'd happily do them.

Enjoy :)

Work Text:

"Anika, please put that down."

"Haru, no- you can't rip Mr. Teddies head off..."

"What did we discuss about hitting people, Ren?"

"Do I need to call your mummy, Yuko?"

"Haru! What did I just say- stop ripping-"

A resounding rip echoed across the classroom.

To say Izuku was stressed was an understatement.

He'd studied hard throughout his life. At first (when he was 3 years old) he aimed to be the Number 1 Hero like All Might.

Things didn't go according to plan when one day his lovely doctor called him and his mother in for a checkup. It was then that they all found out, he had the infamous extra bone in his toe.

Having an extra bone in his toes was odd enough. Then came the mind crushing news that there was no such thing as a quirkless hero. None were ever recorded and every quirkless person who was asked about heroism all said it was far to dangerous for them considering they couldn't defend themselves.

He supposed he understood, but deep down, in a distant part of his soul- he was adamantly resentful.

After the news, he tried to imagine other dreams and aspirations.

He could be a doctor! The only problem being, he found medical information challenging to remember.

Ok, maybe something different- same field- a nurse? That sounded nice. He didn't need as many qualifications (although he would admit, most nurses did ten times the jobs that doctors did). He looked at the University course... and clicked right back out of the windows browser. How the heck were they suppose to remember all those medications and laws!

He could help in other ways like being a Fire fighter! So, he took a day course, went home and collapsed onto the bed in exhaustion. Those fire fighters were the real heroes... clearing up after the destruction the pro heroes caused.

That was when he realised being a hero wasn't all it cracked up to be. Sure, it sounded cool when he was 3 years old but now- not so much. 

It seemed far too imbalanced between the pro heroes compared to the heroes behind the scenes.

Like the first aiders, the demolition team, the fire fighters.

When the pro heroes went home to rest up and lick their wounds- the real heroes worked day and night to clear up anymore dangers to the public.

That was when, one day as he walked home from his mothers house he spotted a poster in the window of a school- it was a quiet little neighborhood and was walking distance from his apartment. It was a position for a teaching assistant. He'd done a minor college course for early child care as it was mandatory for his medical education but that was about it.

Luckily, it didn't require any previous university qualification because it was only a teaching assistant position.

He went back home, scheduled an interview with that same elementary school, went for said interview and boom- he got the job!

The first day he met the class, he wore a red sweater with a collared shirt underneath and black slacks. His thick framed glasses hung high on his nose as he smiled kindly at the little precious kids.

"Good morning class." Mrs. Viola announced in a more than exaggerated way.

The class replied in kind.

"I'd like you to meet a new person today- say hello to Mr. Midoriya."

He stepped forward confidently and gave a wave. "Good morning everyone!"

He was met with painful, awkward silence. Multiple untrusting eyes watching him.

Maybe they hadn't heard him?

"I said good morning everyone?!"

Silence again.

God this was awkward.

A small hand rose up and he, on instinct gestured them to speak.

"Why've you got dirt on your face?"

"Dirt?" He muttered and put a hand up to his face, scrubbing violently. Meanwhile Mrs. Viola started reprimanding the student, telling him that wasn't a nice thing to say.

He was mortified by the suggestion that he had something on his face for half of the school day until he went to the bathroom, took a look in the mirror and realised the kid was talking about his freckles... He'd only lived with them for his whole life- so he forgets they're there sometimes.

After two years of being a teaching assistant, he asked the principal of the school, Principal Oona for a promotion. Going from teaching assistant to teacher, with his own classroom, own homework and own students.

She warned him with a quick 'are you sure you want that?'. He nodded vigorously and so he managed to work his way up the work ladder and got his own class.

His students, compared to the other classes, were absolute angels (most of the time). He was so grateful when his first day as a teacher rolled round- he stayed in the play ground to introduce himself to the parents and family members and watched proudly as his class lead themselves single file into his newly decorated class room.

He didn't want to tell any of them but he secretly spent all of the day before making the different paper and cardboard decorations. Each one depicting a profession to be admired. It allowed the children to aspire to be anything and everything they wanted. Although a student recently told him they wanted to be an panko bread crumb so he would have to add that to the drawings...

And he knew he shouldn't have favorites... but, there was the sweetest little girl in his class. She was so shy and quiet when she was first introduced. The principal didn't tell him much, only that she was rescued by a pro hero bust in the nearby city, she was severely traumatised and needed to socialise with kids her age to help her development. They decided on his class because he, apparently, had a way with the kids.

She grew more confident slowly, but still enjoyed her own company rather than hang around in big crowds. She also gravitated towards him because she liked his sweaters? Really random, but kids were like that.

He'd never actually seen her being picked up either, which was weird. She'd always be taken out of his class early for pickup. He guessed it was because her care givers were from the local authorities and the work schedules had to line up? He never expected it to be so different.

Until one day, after he was finished reprimanding his class for being more than boisterous that day- hence the screaming, ripping and tantrums. He was about done with the day by 11 o'clock.

The bell for breaktime sounded and it was like music to his ears. "Alright class, everyone have fun!" He barely saw the last student escape out the door a second later.

He sat down in his comfy chair, swiveled a little to get more comfortable and leaned down to get out his overnight oats from his briefcase. He stuck his spoon in his mouth and rose, his eyes instantly caught sight of a head of white in the corner of the class. The spoon dropped onto the table and clanged to the floor.

Little Eri was sat drawing calmly.

He smiled, she was a curious child.

"Eri..." He spoke from across the classroom.

She didn't reply, too busy in her art work to notice she was being spoken to.

He stood up and approached her, his oats forgotten on the desk.

She had her head down, her eyes tracked each line she drew.

From the angle he was at it looked like an elephant?

No!

A cow...?

"Eri..." He crouched down to her level, winced a little at the cracks that came from his knees and waited for her to finally rise her head.

She looked up, their eyes meeting and a second later she was scrambling to hide her piece of paper as if it held some sort of secret.

"Mr. Deku." She murmured, teeth biting at her lips nervously.

Deku was a nickname the class gave him one day when they were learning to read Kanji. His name, Izuku, looked a lot like Deku. The word usually meant useless and he begrudgingly admitted it fit sometimes with how he felt but Eri spoke up that it could also mean 'you can do it' and so Deku stuck.

"Aren't you going out for breaktime?" He asked softly.

She shook her head back and forth adamantly.

"Can I ask why?"

"Yes?"

Right, children needed simple words.

"No, what I mean is- why don't you want to go for breaktime?"

She looked at him as if he'd grown two heads. 

He waited expectantly for her answer.

"I was drawing."

"Yes, I can see- it looked very nice, was it a..." Pick a random animal! "Horse?" He waited, she didn't react so he continued. "It's a very pretty horse."

He thought he got it spot on before her face contorted into a most offended one. "It's not a horse, Mr. Deku!" She declared loudly.

"I'm sorry Eri." It really did look like a horse... "What is it?"

She all of a sudden looked nervous again, eyes darting all around. Her hand crunched the paper between her fingers. He heard a faint rip before she decided he was allowed to see it. "My family."

It took him by surprise.

He didn't know she'd been adopted yet. The principal said she would tell him once she was. Unless this was the authorities that collected her from school?

His inner conscious couldn't help himself. "Can I see?" He wanted to know if he could be able to make out who was in the picture. It was a selfish thought, but he'd regret it later. Right now, he wanted to see it.

She slowly unraveled her hand and showed her master piece to him.

He should've known...

It was a black blob with four legs and yellow eyes.

"Ah..." He gulped. "That's lovely, Eri."

Being a teacher was tough, you had to be a multitasker, a mind reader and have an acting qualification.

But it was all worth it.

She looked so proud of herself as she held up the paper, her little face glowing.

After she showed him she quickly hid her art work again, just as the bell rang for the class to come back in.

He groaned slightly at himself for not eating his oats but they could wait until lunch time rolled round.

His students, after using all their energy at breaktime were completely changed when they returned.

They were angels once again, answering the questions when he needed.

When lunch came around he was finally left to eat his chicken salad and his leftover oats.

The day started hellish- then all of a sudden the switch flipped and it was calm again.

He hoped it would last.

By 2 o'clock, the time Eri was usually collected by the principal, he was slightly worried when no one came for her.

As the minutes ticked on, 2 o'clock- 2:15- 2:30, and then 2:45...

He only snapped out of his thoughts when the end of school bell chimed and Eri was still sat happily in her seat.

The rest of his students began leaving, packing up their bags and lunch boxes and putting on their coats with the help of the teachers.

When he returned from wishing all the parents and families goodbye and announced that he'd see them tomorrow. He was shocked to still see Eri sat at her table. 

He approached her table once more- like he did in the morning and crouched down.

She looked up at him expectantly. "Mr. Deku, what's wrong?"

He pinched himself under his sweater, this definitely wasn't a hallucination.

"Eri, you're still here." He said dumbly.

She looked at him as if he'd just said the queen of England was British. "Yes?"

"Who was set to pick you up today?"

She hummed as she thought. "Papa said it'd be uncle Kacchan."

Papa?

Uncle Kacchan?

So Eri had been adopted?

"Eri you have a papa? I'm so glad." He sighed in relief.

She was finally getting the upbringing she deserved.

"Mm, my aunties and uncles come and collect me sometimes."

He could almost cry in happiness, she had a big family.

"How many aunties and uncles do you have?"

She paused and counted on her fingers. She counted past 4, 6 and 10. He started to get suspicious when she started counting into the 20's. 

"I have 18 uncles."

His mouth rolled open.

"10 aunties."

His chin hit the floor.

"And two papas."

Big family was an understatement.

Wait, two papas?

She was being raised by two men?

He breathed a sigh of relief.

She would be so looked after and spoiled when she got older. He couldn't imagine that she'd turn out to be a brat though. She would be very grateful for whatever gifts she received. 

It made him wonder.

He hadn't had a parent be so late for collection in a while and for it to be her was very odd.

"So, your uncle Kacchan..." He rocked back onto his butt and sat on the floor, his knees growing tired from crouching for so long. "Has he picked you up before?"

She made a noise as if to say yes, her mind still on counting her large family.

"Is he normally late to pick you up?"

She stopped her counting and looked him dead in the eyes. "My papa said that if Uncle Kacchan is ever late to pick me up he'd get rid of him forever."

Izuku gulped.

That was... extreme.

Although he supposed he understood.

If it was his child and a relative didn't pick them up in time, he'd be angry too. But to say that in front of a child?

"I see."

Uncle Kacchan was in SO much trouble.

A commotion in the hallway caught his attention, the heavy banging of doors had him sitting upright.

Deep footsteps grew closer to his class room and the door swung open a second later.

In front of him, standing in the doorway of his class room was Pro Hero Dynamite. Number 3 on the hero ranks, 6th most successful rescues of all time and 2nd in the Hottest Pro hero magazine (not that Izuku ever read it...or followed it.)

His words got stuck in his throat.

Why was Pro hero Dynamite here in the school out of hours? Was the school under attack? Was a villain here? Why-

Smoldering red eyes met green and he opened and closed his mouth like a fish.

"Fucking there you are-" Dynamite said, hands retracting from the door.

He took a step forward, then another and for a second Izuku swore he was walking towards him.

Was this a hallucination? Was this whole thing a dream? A weird dream that involved his favorite student being left late and her provider being Pro Hero Dynamite and the only way said Pro Hero could express his gratitude was to ask him out on a date?!

He almost combusted on the spot in embarrassment as the heroes boots stopped by his feet.

He looked up at the hulking man who had his hands on his hips.

Izuku's eyes tracked from the toes of his boots to his knees, further up to his stomach where the big orange X was and then to his the spikes on his head.

Dynamite was really here, in his classroom.

Izuku was about to thank the gods for such an opportunity before a giant squeal ruptured his ears.

"Uncle Kacchan!"

A flash of white flew past him and managed to safely end up landing in the strong arms of the Pro.

Izuku watched as a small smile lit up the heroes face.

He stared in awe.

The Pro Hero Dynamite... the hero that was infamous for being unfriendly and aggressive was smiling at Eri.

He really had to stop saying Pro Hero... it was just Dynamite.

"Uncle Kacchan?" He repeated.

The soft moment between the two stopped and Dynamites smile dropped. It was instead replaced with a dirty sneer. "Don't ever call me that."

"Uncle Kacchan! Don't be mean to Mr. Deku." Eri spoke and it was the only voice Dynamite seemed to calm around.

"Mr. Deku?" He said as if he was trying to remember where he'd heard the name before. "Ah, Mr. Deku!" He shouted as if he remembered.

Izuku looked up, hopeful, until he saw Dynamites face drop again. "Never heard of you. What're you doing in a school, weirdo?"

"Weidro?!" Izuku could handle being called anything within reason, but that was crossing a line. "I'll have you know I am Eri's teacher so keep your tongue behind your teeth next time."

Eri and 'Uncle Kacchan' were silent.

Both of their red eyes wide as they watched him slowly rise up from the floor.

Izuku wasn't finished though. "Actually now that I think about it. Have you checked the time? You're awfully late for pick up time- I guess I'll have to let Eri's papas know just how late her uncle 'Kacchan' was today..." He met Dynamites gaze before turning half way through his rant to head towards the company phone on his desk.

Everything happened so quickly he barely registered it until he felt a weight pulling against his leg.

He looked down at the white haired girl who clasped her hands and legs around his right leg. "Eri!" He tried prying her off but she wouldn't budge.

Determined, he started to drag himself over to the phone as if to prove a point and was slightly satisfied when he heard a shout from behind him. "Hey- wait, damnit!" Dynamite called.

Izuku turned, eyes challenging. "Oh?"

Dynamite didn't say anything just looked off to the side. He looked to be having an inner conversation with himself.

Izuku had enough. "Well then I guess Eris's papa will have to deal with you."

That got a reaction.

"I'm sorry! Alright!"

Izuku hid his smile.

The great and proud dynamite aplogising? Maybe this really was a dream.

"Just don't call Aizawa, alright."

Aizawa?

As in Aizawa Shoto? Pro Hero ErasureHead.

Eri's papa was ErasureHead!

"Oh-I wont be calling him, her other papa I'm sure would be super interested." 

"No! Please, Hizashi will kill me!"

He kinda liked Dynamite begging.

But more interestingly.

He now had the second papa's name.

Hizashi.

He remembered back to his early teenage years of trying to remember all Pro Hero names for an entrance exam.

Hizashi had come up before but where?

"I can't be deaf for another week of my life!" Dynamite said, eyes distant as if he'd experienced it before. 

The comment confused him so he looked down at Eri. She was watching him with big red eyes. "Dada said he'd use his quirk to scream into Uncle Kacchan's ears."

A quirk that allows its victims to become deaf?

Oh!

Of course.

Hizashi Yamada! Pro Hero President Mic.

On the one hand, he really wanted to see the arrogant hero be put in his place by two angry dads. But on the other, he kinda felt for him. The punishments seemed radical. But they were dealing with a Pro Heroes child.

"Please Mr. Deku. Don't let uncle Kacchan get in trouble." Oh no... she was using her cute face... She pouted in despair and her chin wobbled. It crushed his heart.

"Fine- for you Eri, I won't do it."

The weight on his leg immediately lightened and she ran up to her uncle.

He approached them again as 'Kacchan' lifted her easily onto his shoulders. "So, your uncles and aunties are all Pro's?"

Eri leaned down and whispered into a confused Dynamites ear.

"Oh yeah. We take turns collecting her. We can't cause too much of a stir for the kids and families so we collect her earlier than others."

Izuku could see why. Having any Pro there would cause an all out stampede.

"Right. I believe proper introductions are in order." He shot his dominant hand out. His voice slightly wobbly. "I'm Izuku Midoriya, Eri's teacher."

Dynamite took his hand and alarm bells rang in Izuku's fanboy head to never wash that hand again.

"Katsuki Bakugou." He provided, a neutral expression on his face.

"It's nice to meet you finally, Bakugou." He smiled warmly as he placed his arm back where it was, trying to not seem to awkward. Was he being weird? Was he staring too much? Did Bakugou still think he was a weirdo?

"Yeah, whatever." He expected as much from someone as rude as Dynamite.

"Come on, squirt." He rolled his shoulder and jostled Eri slightly, she squealed in delight. He grabbed her book bag and lunch pack and slung it over the other shoulder.

He left through the same door he entered without looking back.

Izuku vaguely heard them talking as they walked down the hall.

When he got home to his first floor apartment, he was greeted with the same washing up he's been putting off for the past two days. It wasn't a small apartment but it wasn't huge either. With only one bedroom, a lounge that lead into a kitchenette and a bathroom- it was enough for him.

He caught up on his marking and slowly fell asleep on his couch in the same clothes he wore that day.

It was a regular routine he went through.

Get home, try to find the energy to clean up, mark the kids homework or papers and then collapse into the couch. But no matter the time, he always wakes up on time to get ready to go to work the next morning.

The next day at school they were discussing heroes. Izuku spoke to them about the people who worked in hospitality, in the healthcare sector and the more hidden heroes like therapists.

"When I grow up." Little Ren stood up from his chair, a confident look on his face. "I'm gunna be just like the Number one Hero Shoto!"

Izuku almost sobbed. It showed his age that in his time the Number 1 Hero was All Might. He almost fainted once when a little girl asked him WHO All Might was.

He really wasn't THAT old.

But to the students, he might as well be a dinosaur.

"That's nice, Ren. Does anyone else want to share their dreams?"

A symphony of arms rose and he picked one off at a time.

They ranged from Pro heroes to hospital worker to janitor and then to princess, knight etc.

He should've known there would be a few...

"All of your dreams are achievable- believe in yourselves!" He said to finish.

Until a little hand rose in the back.

Eri had her hand up. "Yes, Eri?"

"What's your dream, Mr. Deku?"

He didn't expect it but it showed him that she had an extraordinary sense of empathy. She was actively asking him a question.

"I-" He didn't know how to reply at first. "I dreamed of being a Pro Hero, like some of you. But, I realised that I can help in other ways. Like making all of you smile and laugh."

A lot of them laughed at that except Eri who didn't look completely satisfied with his answer.

"My uncle Kacchan says that anyone who doesn't have the guts to be a Pro is a wimp."

The laughter stopped and Izuku felt his hackles rise for the first time at a comment by a student. Children said silly things and it was part of his job to not take it too personally. But that hit a nerve, because it sounded like something Bakugou WOULD say.

"Well Eri... Your uncle Kacchan is very mistaken." He would only go this far for today but if she said something similar again, he would have no choice but to correct her.

She was taken out at 2 o'clock again.

No Bakugou today. 

The next day as well, she left at 2 o'clock sharp. One of her uncles or aunties must've picked her up.

It wasn't until a week after he first met Bakugou that he showed up late again.

He was sat with Eri, squashed into one of the kids chairs as he spoke with her.

He checked his wrist watch again. 3:30pm. Half an hour late for pick up.

Just like last time, he heard the heavy footsteps before his classroom door slammed open.

He didn't even look up to greet him. The anger he was feeling was slightly taking over his head and he feared he'd say something stupid in front of Eri.

"Yo brat." Bakugou greeted.

Eri flew out of her chair again and into his arms, giggling hysterically.

Izuku's eyes didn't leave the seat she just jumped out of.

How could he handle this in a professional manner?

When Bakugou was about to turn around Izuku spoke up. "Mr. Bakugou. I do remember from last week, that I hinted if this happened again... I'd have no choice but to contact Eri's parents."

The boots squeaked to a stop against the shiny floor. "Hey, it's not my fault-"

Izuku interrupted before he got a chance to explain himself. "Oh, I'm well aware of your job and what it entails. But the other Pro's seem to come on time everyday- so why is it so hard for you to do the same?"

"Now listen here-"

"I will remind you, it is not I who will be strung up and punished." He continued after a breath. "Wednesdays are your day to collect Eri, correct?"

He was silent.

"I'll take that as a yes." He enjoyed being right. Especially when he was right against such an arrogant person. "I understand if its hard to collect on time but we were informed all of Eri's pickups worked around your schedules."

"I'm here now, aint I?!" Bakugou defended.

"Look." Izuku rose from the tiny chair and met Bakugou's eyes. "I'm not here to be the enemy. My job is to keep Eri safe. Whilst she's in school, she is my priority. If her care takers arrive late, I have to inform her parents."

Eri started to protest before Bakugou stopped her. "Alright..." He submitted.

Izuku thought his ears had stopped working.

Had he just said alright to Izuku calling her parents and him suffering for it?

"What do you want?"

The question came out of nowhere.

"What do I want?" Izuku repeated.

"Yeah."

"What do I want with what?"

"With me, idiot."

Izuku was completely lost.

He wanted a lot of things. A new TV, a softer mattress. But from Dynamite? The person who's very presence makes his blood boil. He could imagine what he wanted with the pro, but not right now. That was for later when he was alone.

"You want an autograph? Money?"

Izuku didn't know whether to be offended or in awe of the odd idea that sprung into Bakugou's mind.

He went with offended. "Excuse me? Are you bribing me?"

"Everyone wants something from me."

Izuku could almost reach over and slap him across the face.

To be so arrogant! So confident! So stuck up!

"I-" He almost couldn't get his words out. He was so stumped by what he was being offered.

Bakugou waited, an eyebrow raised as he rocked Eri on his hip.

Izuku thought for a moment.

What if he took him up on that offer? What if he managed to keep quiet about it and he gained something in return. But what? It would have to be something that put Bakugou through what he deserved. What could he think of...

His eyes caught sight of a poster the principal gave him earlier and an idea lit up in his head.

"Alright." He admitted. "I'll bite."

Bakugou looked like he'd won. Like Izuku was a typical fanboy.

Oh how wrong he was.

"We need a Pro Hero for our Pro day." He announced, walking over to the brightly coloured poster stuck on his tack board.

"What?" Bakugou asked dumbly.

The words 'PRO DAY' proudly displayed across the title.

"Each class has invited a Pro Hero to join them for the day. I'm the only one who hasn't- frankly I'd rather invite a nurse or doctor in- you know, people who actually save lives." Maybe that was a low blow but in that moment he didn't care.

He felt an immature amount of pride as he watched steam appear out of Bakugou's ears. "I'm not coming to some stupid-"

"Then I guess it's goodbye Pro Hero Dynamite. May he rest in pieces."

"Alright fine!"

Izuku one, Uncle Kacchan zero.

The kids were excited when it was announced that their lovely teacher Mr. Deku was bringing a top three Pro in. 

On the day, he worried Bakugou wouldn't show up.

He spent his whole morning routine doing things in the wrong order then his train was late- which is very rare... Then as he sat himself down to finally set his work up big clomping boots entered his classroom.

He groaned out loud and slammed his head onto his desk.

He'd thought he'd get at least 15 minutes to himself to get ready for the day.

"Morning Deku." Bakugou greeted as if it was acid on his tongue and Izuku could tell he was using his name is the derogative way and not in the 'you can do it' way.

He lifted his head. "Good morning, Pro Hero Dynamite. The kids should be arriving in fifteen minutes time. If you would like a coffee before we begin- there's a machine in the staff room-" He tried his best to be nice. To smile and offer a helping hand.

"Nah..." Bakugou said as he dragged an adult sized chair to sit on the other side of Izuku's desk.

Just to add cherry on top of the cake, he sat down, swung back in his chair and slammed his dirty boots onto his desk.

A vein popped in Izuku's forehead.

Breathe Izuku. Breathe.

"Would you mind removing your feet from my desk?" He said through cracked teeth.

"Yeah I would mind." Bakugou replied.

Izuku's hand felt around blindly for something blunt to chuck at the hero before one of his students walked in 10 minutes early.

The kid was obviously eager to see who their Pro was. He stood frozen at the door, a half eaten yogurt pouch in his hand.

"Ah, Hikaru. Welcome!" Izuku snapped into teacher mode. "Take a seat and we'll wait for the rest of the class."

He ignored Bakugou's presence until all of his class arrived. Eri arrived in the middle and gave the hero a small wave- she was obviously told not to make it known she was Dynamite's niece. A smart move on her parents side.

"As you can see, we have a very special guest with us for Pro Day!" Izuku began, standing just in front of the black board. "Please come up and introduce yourself."

Bakugou didn't need to be told twice luckily- maybe he was under orders to behave as well?

He came to stand next to Izuku.

He loomed over him greatly. He'd read somewhere that Dynamite was a good 6 foot 1 - 6 foot 2 with his boots on.

"The names Katsuki Bakugou and I'm Pro Hero Dynamite!" He declared, setting off a few explosions in his palms.

Izuku allowed it, the kids looked amazed and so happy he didn't want to ruin it by telling him that the use of quirks on site was prohibited.

An almighty roar of kids screams and yells of joy blasted towards them. A few of the girls, who were obviously BIG fans were gushing and talking to each other in excitement. The boys were just happy they had such a cool hero for Pro day.

"Alright, I'm sure you all have questions of your own. Mr. Bakugou-" He pulled the chair he was previously in to sit at the front, positioning it so Bakugou was sat facing the kids. "If you please." He gestured to take a seat and Bakugou did.

Once he sat his butt down it was like being interviewed by paparazzi.

"One at a time. Everyone calm down-" Izuku tried hard to not smile at the look on Bakugou's face. It was obvious he hadn't experienced kids much before.

"Mr. Bakugou!" Devon on the front row put his hand up.

Dynamite chose him first.

"What's your favorite colour?"

It seemed Bakugou was confused by the question but then again he had to get his around the fact these were kids and they would ask kid questions. They weren't some reporters trying to get a scoop.

"Green, next!"

"What's your favourite food? Mines my mums Soba."

"Anything spicy."

"How old're you?"

"30."

The class let out a collective gasp.

"What?!" Bakugou exploded.

"30 is old." One kid replied.

Bakugou looked over at Izuku who wiped a tear from his eye dramatically. He was the same age and if he had to suffer the age abuse, so did Bakugou!

The questions continued.

"Are you married?" One of the blushing girls asked.

"No."

"Eh! Why not?"

"Haven't found the right person."

Alright that was enough questions. Dynamite looked as if he was about to combust.

They got on with their lesson with Bakugou helping out where he could.

Izuku was actually surprised he was doing as he was told. At break time when the bell rang, none of the students wanted to leave for breaktime. They'd rather stay in with Dynamite. It was cute honestly.

"Go out and play you brats!" They followed after him like velcro.

Izuku watched in amusement as he ate his brunch time snack. It was quite entertaining.

"Leave me alone!" He shouted at a little boy who wouldn't leave his side.

The boys eyes went wide before tears started pooling in his waterline.

Izuku was straight up out of his chair, ready to console the boy and tell Bakugou off when all of sudden Dynamite knelt on the floor, a panicked look on his face. "Shit- I didn't mean it!"

Izuku watched as he wiped the tears off with a gloved hand.

So there was a caring side to the stoic hero?

"Look kid-" Bakugou said.

He held out his palm to the boy and lit up a few sparks. It mesmerized the kid who instantly stopped crying and started smiling wobbly. "It's pretty, right?" 

Izuku sat back down, conceding, maybe Bakugou Katsuki wasn't THAT bad...

By the end of the day, he managed to survive the onslaught of parents that wanted autographs. They practically beat down his door after hearing Dynamite was there.

Bakugou placated them until they finally were satisfied and left with smiles on their faces.

Izuku slumped back into his desk chair and swiveled around to drag his laptop out of his briefcase. He needed to do his notes before leaving otherwise the principal would tell him off again. If it wasn't documented, it didn't happen was her favorite quote.

He was interrupted by a thud.

He looked over the lid of his laptop.

Bakugou was back to sitting opposite him only this time he didn't have his dirty boots up on the desk.

He was sitting politley for once.

"What's this? A day in the classroom and you're a changed man?" Izuku teased.

Bakugou growled in warning. "Yeah right. I just came to say-" He paused as if what he was about to say was physically hurting him. "You did good. Those brats- they know their stuff."

Izuku almost fell over the back of his chair.

Had he heard that right?

"I'm sorry? Could you repeat that?"

Bakugou's face fell once more. "Forget it."

"No wait! Please!"

The slam of the door as Bakugou left had Izuku smiling widely.

Yeah, maybe Bakugou Katsuki wasn't so bad...

Notes:

This is an open ending but if you guys want a summary:

Katsuki keeps showing up late for his pick up times every Wednesday. Izuku and he talk during his pick ups. Izuku starts calling him Katsuki after months of knowing him. Then Eri convinces him to call Katsuki 'Kacchan' and it sticks. 7 months later Katsuki starts noticing he's falling for the green haired nerd teacher and asks him out (he's very confident) Izuku ofc says yes because he also started falling for him somewhere along the line and they have their first date in a restaurant owned by Sato. The word spreads that Katsuki was on a date with Eri's teacher in the hero community and Aizawa and Hizashi are a little creeped out by it - considering its their daughters teacher but they accept it after meeting Izuku who is the sweetest.
