Okay, so, literally—this is my first fic of any fandom and any pairing in more than 10 years. I resisted to call to write a BKDK for all of 3 months before I finally caved. I wrote this over the course of a week. It is a bit wordy (10,543 total) in some places, and I apologize for that. This is a song fic of sorts—I was inspired to write this after listening to That's All by Genesis, and just got hardcore BKDK vibes.

Synopsis: Tired of being strung along, Midoriya Izuku ended his 2-year relationship with Bakugou Katsui. He breaks off all contact for 6 years, and has been in America the last 5 of them—where he has become Number 1. An unexpected situation brings him home for the first time since leaving, and face to face again with the man who broke his heart. But it's alright, because he's totally over him now, right? Riight…

That's All

"Izuku? It's about Inko."

Even with all his 6 years of being a Pro Hero since graduating from UA, that had been the single most heart stopping phone call that Izuku had ever gotten.

He was walking down the halls now of the hospital's 5th floor, looking for the room number the receptionist had given him. But before he'd even gotten close to the door, the sight of a familiar figure let him know he was in the right place.

"All Might!" Izuku's strides quickened until he reached the lanky blond, whose professional looking suit was still entirely too large for him.

All Might's face also lit up when he recognized Izuku, and embraced him roughly and affectionately.

"Young Midoriya!" All Might sounded like he was holding back tears as he pulled away. "You've grown so much."

Izuku's first inclination was to disagree, but upon realizing that he was staring about eye level with the tall hero, he realized that he couldn't.

"I guess I hadn't realized," Izuku smiled brightly.

"Five years away will do that," All Might laughed, "And it looks like the States have been agreeing with you."

Izuku scratched the back of his head in embarrassment.

"It's nice of you to visit Mom," he changed the subject. "How's she doing?"

Although heart-stopping at first, it turned out that Inko had only slipped a disc in her back. She was in the hospital now recovering from a procedure that had fixed it.

"She'll be ready to jump back up now that you're here," All Might stepped from in front of the door. "Don't let me keep you any longer."

"You're not staying?"

All Might checked his watch.

"It's already almost 3," he informed, "I've got a meeting with the Hero Commission soon. I'll call you before you leave, and we'll get lunch together."

With a firm clap on the shoulder that would've sent Izuku flying 8 years ago, All Might left.

Izuku walked through the hospital room door and smiled in relief to see his mother, lying at an angle, and fighting with the remote attached to the bed.

"No, that's not it," she pushed another button. "Not that either...Let's see—oh! Sorry nurse, I didn't mean to call you."

Izuku cleared his throat and smiled widely. She looked up and gasped, dropping the remote and bursting into tears.

"IZUKU!"

Izuku quickly, but gently, embraced his mother as she buried her wet face in his neck.

"Mom, be careful," his voice muffled as his cheeks were caught between her shoulder and her head, "Your back is still healing."

After a long while, she reluctantly let go and reached for the bedside tissue to wipe her face.

"I'm sorry, sweetie," she sniffled, "I'm just so happy to see you."

"You saw me 8 months ago Mom," Izuku sat down in the chair beside the bed, "When you came to visit."

"8 months is entirely too long. She shouldn't have to break her back for her own son to come and see her."

The voice came from the door, and Izuku looked up to see Mitsuki walking into the room. She came all the way in, stopping in front of Izuku and ruffling his already messy hair affectionately.

"Hi Auntie," Izuku didn't even try to fix his hair back.

"Don't make your mother worry so much, just because you're a hot shot pro now," Mitsuki grinned, taking a seat next to Izuku. "How are you doing today, Inko?"

"I feel much better! Izuku is taking me home tomorrow to look after me," Inko enthused, looking over warmly at her son, "But I'm not worried about him. I just miss him."

Her words sent a pang of through his chest, which was quickly replaced by a stab of terror as yet another visitor walked through the door.

"Hey Old Hag! I told you to stop sticking me with your goddamn paperwork. That receptionist is a moron!"

Kacchan came into the room, and violently handed his mother a visitor's sticker with her name on it. Mitsuki snatched it away with equal violence.

"Shut up, you ungrateful brat!" she bit back, "you're lucky I even waited for you to come at all!"

Kacchan's eyes finally landed on Izuku, and the latter's heart began pounding directly against the inside of his sternum.

The years had not simply been kind to Kacchan—they had been downright generous. The blond was much taller, much more filled out, leaner, and mature looking in all the right ways. He was wearing his hair a little shorter, but still sporting all black clothes that were too loose and baggy.

They still did nothing to disguise the perfection that was his body.

Tense awkwardness flooded his system as Kacchan's red eyes kept his green ones locked in place. The stare lasted all of 3 seconds, but felt like 3 centuries to Deku, before Kacchan finally released him.

"Well, looks like a nerd found his way back into the country."

Izuku swallowed hard willing himself to say something, anything, and for once, be able to wear his heart tucked firmly inside of his sleeve.

"Hi Kacchan," was his lame response.

Try as he did, Izuku's mind couldn't help but wander back to the last time he'd seen Kacchan in person—at their high school graduation 6 years ago.

The ceremony was over, and Izuku held his rolled up diploma in his hand. He was making his way through the courtyard, densely populated with students and their families, in search of one in particular. This was exactly the kind of crowd that Kacchan hated, and there was one place that he'd always go to get some quiet.

Izuku found his way to a secluded glade on the outskirts of campus, and sure enough, there he was, standing underneath a blooming Sakura tree.

"Kacchan!" Deku smiled excitedly, running up to meet him. "Everyone's looking for you. The class wants to take a picture together."

"Tch," he scoffed, "why do I gotta be in some stupid picture? Was this pink cheeks' idea?"

Izuku's grin widened as he took Kacchan's free hand in his.

"It's graduation. Just this one time, be cooperative?"

Izuku stared up at Kacchan, who was slightly talker, with a silent plea in his green eyes.

Kacchan frowned and leaned down, kissing Izuku suddenly and passionately enough to make him gasp. He quickly recovered, however, and returned it with equal passion, letting go of his hand and leaning into Kacchan's body.

Kacchan snaked his fingers through Izuku's green curls and kissed him so hard and so deeply, Deku started to feel dizzy.

They finally broke apart, and Kacchan stared intensely at Izuku.

Without thinking, and before he could stop himself, Izuku spoke what was in his heart.

"I love you, Kacchan."

The effect was instantaneous. Kacchan froze, and the silence that followed was palpable.

Izuku raised a brow. At length, he finally replied.

"Yeah."

Izuku wasn't sure what he had been expecting, but it wasn't that.

"Yeah?" he extricated himself from Kacchan's grasp. "What does that mean?"

"It means I already know that, shit nerd."

Now it was Izuku who frowned.

Although he'd felt it had been pretty apparent, he'd never actually said it out loud before. This was supposed to be a big first in a relationship, and after nearly two years together, this was not the response that Izuku had been hoping for.

"Is that all you have to say?"

Kacchan's face became unreadable. Izuku hated when it did that. He had a much easier time figuring things out when Kacchan was trying to blow things up.

Izuku sighed and took another step back.

"Kacchan, I just told you I love you, and all I got back was a 'yeah'," Izuku was trying to stay calm. "We've been dating for 2 years—we're moving in together next week. I think I deserve a little more than that."

"Do you?" he sneered. He never liked it when Izuku tried to stand up for himself. "Like what?"

"Like how you feel, for starters."

Kacchan paused, and for a moment, Izuku saw some expression he couldn't place flit across his face.

"I feel annoyed by this pointless conversation,' he said, sneer deepening. "Let's go take the fucking picture."

"Kacchan, why are you acting this way?" he frowned, confused, "Did I do something? Did something happen?"

Kacchan looked at him a long while before speaking.

"Just drop it, Deku," and he began to walk away.

Izuku felt a cord snap somewhere in his chest.

Kacchan hadn't gotten very far before he realized that Izuku wasn't following. He turned to look over his shoulder.

"This is how it's always going to be, isn't it?"

Izuku looked down, trying, and hoping that for once in his life, he'd be able to hold back his tears.

"Hah?" Kacchan turned to face him properly.

"All my life, I've been chasing after you. For as long as I can remember, I've been running after your back."

Izuku squeezed the diploma in his hand tightly.

"No one asked you to," Kacchan said coldly, "And I ain't slowing down for a useless nerd who can't keep up."

Izuku chuckled mirthlessly at that very Kacchan-esque response.

"I don't need you to," Deku's voice had unexpected conviction, "That's not what I want. I just...don't want to keep reaching for someone who isn't ever going to reach back."

Tears finally broke through and started falling down Izuku's face, and he turned his eyes to the ground.

"Deku-"

"It's over, Kacchan. I won't chase you anymore."

Izuku finally braved meeting Kacchan's eyes, only to find that stony, unreadable look had returned.

It was apathy. And it killed him.

After what felt like an eternity, he finally got a reply.

"Have it your way."

That was 6 years ago.

Originally, his plan had been to accept a local offer and live with Kacchan. However, following their break up, Izuku accepted an offer with a prominent agency in Hokkaido—on the other side of Japan, to get away from Kacchan and try to move on with his life. But the explosive way that Kacchan was dominating the news and the rankings made it impossible to escape him, even without being close.

When the opportunity arose, Izuku went across the seas to the United States, and hadn't been back in the country, or in contact with Kacchan at all.

Until now, that is.

And it was just his kind of luck that on his first day stepping foot back into the country, he'd run into the very reason he'd left it in the first place.

"Ah, this is so nostalgic, isn't it Inko?" Mitsuki sighed, "when was the last time the 4 of us were together like this?"

Inko, who had barely stopped crying, started right back up again.

"Not since they were in school!" she wailed.

"Aha, Inko, our boys are grown!" Mitsuki tried to soothe, "at least Izuku has an excuse for not visiting you often."

At this, she glared at Kacchan.

"I got better things to do with my time, hag."

Mitsuki reached up and swung her fist into the back of Kacchan's head, to which he cursed loudly.

"Anyhow, Izuku," she smiled jovially again, "Next time, just don't let so much time pass between home."

Izuku was glad to know that the weird awkwardness he felt seemed to be self-contained. His mom, Mitsuki, and not even Kacchan, seemed to be having any issues.

It had just caught him off guard, seeing Kacchan. After 6 years without seeing him, and the way they had left things, it stood to reason. It wasn't as big a deal after all. He was definitely over him.

Izuku smiled a little and relaxed in his seat.

"I guess I won't," he thought aloud.

"And next time, bring that girlfriend of yours!"

Izuku tensed back up so fast he started choking on his own spit.

"Oho?" Mitsuki nudged Izuku with her shoulder, "A girlfriend? Is that the real reason for the long absence?"

He felt his face flush a deep red and he chanced a look at Kacchan. His face was still unreadable.

"I-I-I-"

"Her name is Melissa Shield!" Inko cut over him, "I met her the last time I visited. She's the prettiest little thing!"

"Mom, that's—"

"Why are you so shy about it, Izuku?" Mitsuki questioned, "you look like a tomato."

Leave it to his mom and Mitsuki to make a 24-year-old man feel like he was in high school again.

"He's probably embarrassed about the way I met her," Inko whispered loudly, "Sweetie, it's okay. You're a young man. I don't expect you to be a monk."

Make that middle school.

Izuku wished more than anything that he'd had a teleportation quirk in his arsenal, so that he could be anywhere but here.

For the record, he was not dating Melissa.

His mom had walked in on he and Melissa in a compromising position on her last visit. After trying to convince her it was nothing, he found that it was easier to just let her continue thinking that.

It seemed to have brought her some peace of mind, thinking that he wasn't alone out there.

"I'm going to get a soda," he announced, standing up abruptly.

"Inko, you ran him away!" Mitsuki teased.

In order to make it out of the room, Izuku had to walk directly past the narrow entrance Kacchan was standing in.

But it was either that, or stay in the room.

Izuku walked by Kacchan, who didn't move a centimeter out of the way, and had to contort to avoid touching him at all. To make it worse, Kacchan was looking at him the entire time.

Izuku thought that it was a good thing that he was in a hospital. If he were going to go into cardiac arrest from humiliation, this was a good place to do it.

Out in the corridor, he let out a sigh of frustration and relief, and all the tension he'd been holding in his shoulders deflated.

Get it together, Izuku.

He took a deep breath in, held it for a moment, and heaved a long sigh.

It's just Kacchan. He wasn't anything to him anymore. Just some guy who broke his heart 6 years ago. It was ancient history and he was over it.

"Deku."

The sound of Kacchan's voice directly behind him made his heart stop for the 2nd time that night.

He turned around and tried to appear as casually unaffected as he could.

Kacchan had his hands in his pockets and was looming over him. While Izuku had grown in the last few years, Kacchan had grown slightly more. He had at least 6 inches on Izuku now.

"What's up Kacchan?" he smiled weakly, "I'm sorry. I didn't know you and auntie would be here, or I would have timed it better."

"Hah?" Kacchan frowned deeply and held his hand up in a familiar threat, tiny explosions crackling in his palm. "That's all you ha—"

Izuku braced for impact, but was shocked when Kacchan suddenly stopped, seemed to think a moment, and then stuffed his hands back in his pockets. Instead, Kacchan just stared at him, very intensely.

And it was then that Izuku realized that he was wrong. He couldn't handle this, and he wasn't okay. He needed to get away from Kacchan.

"I'm getting that soda now," he waved awkwardly and made a break for it before Kacchan could speak again. He headed in a random direction, not knowing or caring if a vending machine was anywhere in his path.

He took his time before making his way back to the room, and when he did, Kacchan was gone.

Although he'd offered several times, Inko always refused Izuku's offers to move her out of that small apartment they'd been in his whole life. Walking through that door that door the following day had been like stepping back through time. Nothing had changed.

Izuku smiled fondly before helping his mother to her bed.

"The doctor said strict bed rest for 2 weeks," he repeated, "and then take it slow after that. Got it, Mom?"

"Yes sweetie, I understand," she hummed patiently, making herself comfortable on her bed.

"If you need anything, anything at all, call for me," he went and got the remote for her, "That's why I'm here."

"I still think you didn't have to take a whole month off," Inko flipped on the television, "but I appreciate it."

Izuku kissed the top of his mother's head and made to leave.

"Get some rest, Mom," he smiled and closed the door behind him.

Izuku stood in the living room and waxed nostalgic for a moment. It was around dusk, and the orange light was pouring into the living room through the window. He could have stood there until the sun went down, basking in the memories, but had to take a shower—he hadn't had one since before he got on the plane.

He grabbed some clothes and a towel, disrobing in the restroom. His time since UA had added a number of scars to his collection—across his arms, his chest, and his back. He wasn't naked in front of a mirror very often, but when he was, he was always noticed a couple of new ones that weren't there before.

He showered quickly, and no sooner than he'd gotten dressed again, the doorbell rang.

"I'm getting it, Mom!" he announced on his way to the door.

When he opened it up, his nostalgia-induced smile instantly fell as he beheld, for the second time in less than 24 hours, the sight of Kacchan in front of him.

Izuku immediately slammed the door in his face.
