Bkdk au where Bakugou is part of a famous rock band and deku is his childhood friend that is a voice coach for kids and makes jingles for animal shelters and stuff.

They’re best friends and hang out whenever Katsuki is home until one day when they are at their childhood park and deku randomly gets down on one knee and proposes to Kacchan.

Katsuki thinks it’s a joke so he says the same thing he says whenever a fan proposes to him at a meet and greet:

“Sure, for $10 million”

Deku laughs and continues their night. They get dinner at Katsuki’s favorite restaurant, which he hasn’t been to in months because touring, and go back home for the night.

And then Deku disappears.

He can’t find him anywhere. He goes to Deku’s apartment and it’s just... gone. There’s nothing left.

He doesn’t understand what happened. They were supposed to spend the whole year together. Katsuki’s band had taken a year off to spend with loved ones and he was planning on spending most of it with deku. ..

But now...

Months pass and he still hears nothing from deku.

He’s at the grocery store one day when he hears deku again

“If that’s what I need to do/ to be able to stay with you/ then I swear by the sky up above/ I’ll buy your love”

What the fuck... it’s a song? Huh?

But Deku’s not a musician... like he makes music and can sing really well but...

He never wanted to be a star. He always said he preferred working in the back- helping others become better and using music to help people...

He never wanted to be famous.

So why would he do this? What was he trying to tell Katsuki? That he was better than him? That he could do what he does if he wanted to? That he could become more famous than him?!?

Katsuki was furious. That little shit. Abandoning Katsuki and tryifn to show the whole world how much better he is than him. Fine if he wanted to rock, he’d show him just how loud he could be.

————-

Katsuki wrote the whole album in a month, each song loud and ready to set the internet on fire.

“Dude, these are all bangers,” Kirishima said when he saw them at the studio.

Katsuki had made the whole band come back early to record all his songs.

He may not have been able to convince them to do a full on tour early, but he’d be damned if he didn’t get to see his albums destroy deku on the billboard charts.

“But are you sure you want to put so many break up songs on a single album? “

“They aren’t break up songs, shitty hair. They’re rock. Now shut up and play the drums like I taught you.”

When they had first started our Katsuki had been the band’s drummer, but when they got signed they were told they needed a male vocal and as the best singer and the one with the most dynamic stage presence Katsuki was the obvious choice.

So he taught Kirishima how to play and joined Jirou up front.

“Well either way, I guess there is no busting out the grand piano on the next tour” Sero says sadly by his keyboard.

“Ohh maybe you should bring back the keytar! “ screams Mina while tuning her bass.

“No way. Keytars are lame.” Katsuki was not gonna have them ruin a tour just for shits and giggles.

“Yeah, because he hasn’t brought them back yet.”

Katsuki was gonna kill a bitch.

Jirou, knowing the signs that Katsuki was gonna go on a rampage, stepped in.

“How about we worry about that when we get there. We need to record these songs before we can even think about a tour.”

“I am excited to do another tour, though,” Kaminari said while messing with his own guitar “oh maybe we could get Mido-OW”

Katsuki moved his hand from where he had smacked Kaminari in the head.

“Let’s just get this over with. Come on Ears, you ready to break the charts?”

————

“You know, Bakugou, if you were going to prod the whole thing by yourself you didn’t have to call me.”Aizawa said watching Bakugou mess with his board.

“Shut it, old man. I just want them to be perfect.”

“Yeah I got it. Either way we really just need a cover now. You got a name in mind?”

“Dynamight “

———————

Just as Katsuki thought, their album topped the charts. They broke their own record for most listens and got amazing ratings by critics.

For some reason the critics seemed to think it was a break up album too, but Katsuki never put much stock in their opinions anyways.

The album was so huge they had to start planning their tour right away, so that’s how Katsuki found himself back at the studio with all the idiots... and jirou and aizawa.

As the meeting finally ended and they were leaving Kaminari felt it necessary to ask “hey did you see what Midoriya said about our album on Twitter? It was so sweet.”

“Oh yeah, “ Mina added, “ it was really nice of him.”

“What?” Katsuki asked.

“You really need to get on Twitter, bro.” Kaminari said as he passed his phone over. On it was a tweet from Deku- “I CANT STOP LISTENING TO DYNAMIGHT!!!!! A BAND REALLY SAID ONLY BANGERS ALLOWED”

CURSE YOU TWEET LIMIT!!! TBC

He scrolled down and saw another tweet from Deku “DO YOU HEAR KACCHAN’S VOICE ON ‘LOSER’ DO YOU HEAR THAT VIBRATO!!! *faints*”

On and on the tweets went. Talking about “kacchan’s voice” and “MINA SHRED” and a bunch of other stupid fanboy shit that was just so ... deku.

Why would he do this? Was he mocking him? Telling katsuki that he would never be as good as him? That he would need his help promoting if he ever wanted to have a chance against him?

That had to be it. There’s no other reason Katsuki could think of.

He had to be mocking him- trying to show him up- if not then... why would he have left?

“Fucking shitty nerd.” Katsuki threw Kaminari’s phone back at him and walked out.

—————

It continued like that for years. Katsuki making album upon album, going on tour upon tour, to make sure he stayed above Deku. Always beat deku.

He did hundreds of interviews and promotional bullshit. Even letting a camera crew into his house.

That interview did really well. Although the next week they released another house tour this time with deku.

Katsuki didn’t want to watch it, refusing to give deku the free promo, but eventually he couldn’t help himself and clicked.

It was much shorter than Katsuki’s. They came into a shabby looking apartment with basically no furniture.

The host even asked deku why he didn’t have anything and he said it was because he had “better uses for his money” whatever that meant.

They went into Deku’s tiny bedroom which had basically just a bed and a keyboard and mic on a desk for him to work on.

“I mostly work in the studio but sometimes if I get inspired and need to get it out right away I’ll write here”

They then moved on to the second and final bedroom “um well I’m a big collector so this is where I keep all of my merch and stuff.”

He opens the door to a room filled with merch from different artists, there was Uravity and shouto and of course All Might merch all over but

The most merch was of Katsuki, or at least his band.

“You’ve got a lot of A Band merch here, huh?”

Deku smiled at the camera, “ of course! I’ve been friends with all of them for years, and I really love their music.”

The host picked up a plushie of katsuki from the shelf, “well it seems like you have a favorite.”

Deku laughed, blushing, “ yeah. Kacchan, uh Bakugou sorry, is my childhood friend. He’s my favorite person in the world so of course he’s my favorite in the band too.”

Favorite in the world? Wtf? What was deku even talking about? He LEFT him. He literally hasn’t talked to him in YEARS. How could he be his favorite person?

—————-

Eventually Katsuki is forced to take some time off by unanimous vote from his band.

They said that they “missed their loved ones” and “ wanted to relax” and some other lazy shit.

Seeing as there was nothing for him to do with the band out of the city he went to his parents.

Spending time with his parents was excruciating but at least they would help him plan outfits for their next tour. Might as well get started on that.

About a week into his visit he had had enough of his mother and decided to escape the house under the excuse of going grocery shopping.

He had only gotten around the block when he ran into Deku’s mom

“Katsuki! It’s so nice to see you! How have you been?”
“I’m good, Auntie. Just on a break.”
“That’s great! Izuku hasn’t taken a break in years. He hasn’t even had the time to visit me. “

“Oh.” He doesn’t know what to say. He can’t exactly complain about deku to his own mother.
“It makes a old woman very lonely. Say, katsuki, why don’t you come visit me? I can make you that curry you loved as a kid.”

“Uh, that’s okay, Auntie, you do-“
“Nonsense! Come on,” she said as she grabbed his arm and dragged him back to her apartment.

It looked just like when they were kids. With pictures of auntie and deku everywhere. There were even pictures of him- him and deku at the beach, him and deku showing their talent show metals, him serenading deku with his first guitar.

“I always loved that picture.” Inko said from behind him.

Once again Katsuki doesn’t know what to say”...yeah”

“You know I have a video of that too. Let me find it”

“Oh you don’t have-“

“Found it!” Inko says taking the tape from the shelf. “It’s good to be organized.”

She sticks the tape in the player and presses play before Katsuki can find a reason to get out of it.

On the tape his him singing the first song he ever wrote with deku.

If you showed it to one of his fans they wouldn’t be able to recognize the sound at all.

It was soft and slow and so off pitch he wanted to throttle himself.

“Cause you’re with me/ we can do anything/ play on the swings/ laugh off bee stings”

The lyrics are garbage, but Deku’s looking at him as if it’s the most amazing song in the world.

FUCK YOU TWEET LIMIT! NOT AGAIN!! TBC

Katsuki can’t look away. He just keeps staring at Deku, and eventually Inko places a tissue in front of him.

“Here you go sweetie.”

He was crying. He didn’t even realize he was crying. Fuck. Why was he crying?

“I miss him too. It’s okay.”

He thought no, that can’t be it.
He was pissed at Deku. He couldn’t miss him.

Couldn’t miss his smile and his laugh and the way he would mumble when he heard a new melody he liked.

Couldn’t miss his ugly shoes and his dumb shirts and the way he was always humming.

But as much as he tried he couldn’t stop crying and eventually Auntie took his head in her lap and pet him softly.

“It’s okay, dear. Cry it out. You aren’t weak for it. It’s just what happens when you love someone.”

Love?

Did he love Deku?

He couldn’t imagine his life without him. Couldn’t picture him hearing anyone else’s voice when he woke up.

He tried to imagine Deku with someone else, and felt sick to his stomach.

It was wrong. He couldn’t do it. Deku was... his.

Deku was his love.

————————

Eventually he must have fallen asleep because he woke with a blanket on him on Inko’s couch.

“Oh good dear. You’re awake. Come dinner is ready.”

The rest of the night went normally and he left a few hours later promising to visit again soon.

He doesn’t want his parents to see his face. One look and his mom would know he’d been crying so he goes back to his own house.

It’s not too far away but by the time he gets off the train he’s ready to head back to bed.

He takes his key out early and walks around the corner to find

“Deku.”

He’s sitting on his doorstep, like he’s been waiting for hours.

“Kacchan.”

“What are you doing here?”

“I need to talk to you.”

Normally Katsuki would have fought him- he leaves for years and comes back with a “I need to talk to you. Bullshit.- but he’s still worn out from his revelation before and he doesn’t have it in him to yell anymore so he just opens the door and lets him in.

“Thanks, Kacchan.” He says as he goes in.

They sit on the couch in silence for a while. Neither knowing where to begin.

“Sooo.. I-“ Deku starts just to be cut off.

“I saw your mom. “ Katsuki says, wanting to be the first to go, “she misses you.”

Deku looks down, “I miss her too.”

“Then why haven’t you gone to see her?”

“I’ve been busy.”

“Yeah I know. Letting fame go to your head.”

“I haven’t-“
“Oh yeah? Then why haven’t you called? Why haven’t you visited me or your mom? Why did you just up and leave-“

“I DID IT FOR YOU!”

Did it for him? The fuck could that even mean?

“How on earth could you have done that for me?”

“Y- you said you’d marry me for $10 million, s-so I got the money.”

...”what?”

“I - I had an offer from All Might studios and I wasn’t gonna take it but

“Kacchan asked for money, which I get- I do- you needed to know I was serious that I would do anything for yo-“

“The fuck?! Deku that was a joke!!”

“A ...what?”

God this was a mess.

“Deku I thought you were joking. I tell every shitty fan that proposes to give me $10 million”

“Yeah but... I -“

“Are you really that dumb? God I can’t believe I’m in love with you.”

“You’re what?”

“Yeah stupid deku. I’m in love with you. I don’t need you’re stupid money I just want you to stay with me. Don’t disappear again. If you do I’ll kill you. “

Deku smiled and leaned over to rest his forehead on Katsuki’s.

“I can live with that.”

“Good.” And then Katsuki kissed him.

Epilogue

A few months later deku posts a video on his Twitter. It’s him and Katsuki sitting in Katsuki’s house- their house now but no one know that yet. He’s sitting on a stool and Katsuki has a guitar on, playing a soothing soft melody.

It’s so different from anything anyone online has ever seen him play. Quiet and sweet and like laying in bed with your love in your arms.

Then Deku starts singing.

“I’ve always been the jealous type/ someone really possessive/ I’m sorry I can’t help it/ I want to keep you with me/ cause there is no place I’d rather be/ then by your side”

Then it’s Katsuki’s turn. They’ve never heard him sing this type of song- slow and soft, no screams and shouts, but his voice sounds like it was made for it. Like he was made to duet with deku.

“I don’t mind/ as long as you stay with me/ I’d battle the ocean and the sea/ to make you mine”

Their voices work in harmony. Staring at each other. Never looking away or towards the camera.

Once they’re done Katsuki leans forward and kisses Deku. Then the video ends.
