(summary/description of story)

When Katsuki got his quirk, Izuku was so proud of him and so excited to get his own quirk... but the time never came, and he never got his quirk. Nonetheless, Katsuki still treated him like a normal decent human being, and was even best friends with him too, not caring if Izuku had a quirk or not.

When Izuku was bullied in middle school, Katsuki was there to help him fight, teaching him how to fight and good ways to do it. Katsuki helped Izuku form into the badass he was in high school, and Izuku helped Katsuki form into a gentler badass when he was in high school. But otherwise, they both were amazing badasses in high school.
Nothing between the two changed negatively, it was all positive. Their relationship got stronger as time progressed. They were unstoppable when teamed up.

As their unsaid feelings for each other bloomed, so did the danger rate for UA High School. Soon, the school was in a war with villains. No one had time to themselves anymore, seeing as they were in a constant war that lasted a few months.
When the war ended, Katsuki's and Izuku's feelings stayed the same... But did they stay the same? Physically and mentally?

Chapter 1 - Childhood Promises

“Wahh, Kacchan’s so cool!! He has an amazing quirk, so he’ll be sure to become an amazing hero!!” the young child said, sitting in the dirt with his best friend. “Of course I’ll be an amazing hero!! I’m gonna be just like All Might, and you’re going to be my sidekick!!” the cocky young blonde stated, picking the nearby flowers. Izuku shook his head, pouting. “Why a sidekick? I’m gonna be a hero too!!” he whined out, crossing his arms. The blonde child rolled his eyes and continued to do what he was doing with the flowers. “Well, when we’re old enough, I’m gonna make you my bride!!” he said, placing the flower crown on Izuku’s head. Izuku giggled lightly at the proposal, but nonetheless said, “Silly Kacchan!! It doesn’t work like that!! But okay!!”

The child sniffled, tears running down his cheeks. “I-I’m sorry, Kacchan! I can’t be your sidekick anymore, I don’t have a quirk…” he cried out, tears streaming down his face. The kid that Izuku was talking to was his best friend, Bakugo Katsuki, also known as Kacchan by Izuku, who was shocked at first, but quickly recovered from his shocked state. He embraced Izuku in a hug, letting the greenette cry into his shirt. “Don’t worry, Izuku! For I, Bakugo Katsuki, will be your hero!!” Katsuki proudly said once the two broke apart from the hug. Izuku looked confused, the hot tears still running down his flushed cheeks. Katsuki quickly whipped away the tears, gently as to not hurt the no-longer-crying child. “Huh? W-what do you mean by that?” Izuku asked, tilting his head slightly. Katsuki smiled proudly, grabbing the greenette’s hands.

“I mean, I’m gonna protect you and become your hero!!” Katsuki confidently said, holding his future wife’s hands. Izuku giggled, his mood instantly boosted with the knowledge that Katsuki would be there for him always, and would even be his hero. “Kacchan, I promise one day, even if I don’t have a quirk, I’ll be your hero!! No matter what!!” the greenette stated, smiling wide. The blonde smiled with him, but let go of one hand and held out his pinky finger. “You gotta promise me it. One day, we both will become each other’s heroes and get married! You will be my lovely wife someday, no matter what!” Katsuki promised, still holding out his pinky for Izuku, who intertwined his pinky into it. Their promise had been sealed, one day, they would carry out the promise they had made, but surely, they would never forget about it.

Haha, Fighting Abilities SUCK.

“Kacchan!! You came!!” the excited greenette said to his blonde best friend, who was equally excited. “Yeah, I did!! I wouldn’t miss your birthday party for anything!!” the blonde said. “Katsuki, Izuku, if you boys want to play together while waiting for everyone else to come then go to Izuku’s room or outside,” Mitsuki, Katsuki’s mother, said, ruffling her son’s hair. The two young boys ran out of the living room to Izuku’s hero-covered room to play. Mitsuki rolled her eyes and started chatting with Inko.

“Do you think they’ll still be friends when high school hits?” Mitsuki asked, leaning a bit in her chair. Inko thought a little while she poured their tea. She answered, “Hmm, I hope they are. They seem like really good friends for right now, but yet again, they’re only 7…” Mitsuki nodded her head, sighing, but then smirking. “Heh, I bet that they’re going to be dating by their 3rd year in high school,” she said, crossing her arms. Inko laughed a little and rolled her eyes, but didn’t disagree, no, instead, she said, “Pfft, how much are we betting?” Mitsuki laughed lightly at the statement, but then spoke out, “If they date by 3rd year, you gotta take me out to a dinner of my choice and pay for it, if they don’t date or date later than that, then I take you out to a dinner of your choice and pay for it.” The two mothers agreed and shook on it, looking forward to the dinner they would have in the far future.

“Hurry up, Kacchan!! I don’t want to be late to school again because of you!!” a familiar greenette’s voice rang out throughout the house. “Yeah, yeah! I know!!” the hot-headed blonde yelled back. Izuku sighed, smiling. Then suddenly, a bigger body tackled him in a hug onto the ground. “Eep!! Kacchan!!” Izuku squeaked in surprise. Katsuki chuckled at how Izuku reacted but didn’t blame him for reacting that way, since it’s how he reacted their whole childhood. “Heh, dork,” the blonde said, getting up, and then helping the greenette up.

“Let’s go now!! I don’t want another tardy on my record!!” Izuku whined, grabbing Katsuki’s hand and attempting to drag him out the door, but failed since Katsuki stood still in that same spot purely out of spit just to annoy the rushing greenette. Izuku quit and let go of him, going behind him and punching his back lightly. “COME ON YOU, SNAIL!!!!” Izuku shouted, managing to push Katsuki out of the house from behind. Katsuki laughed aloud and began walking, causing Izuku to fall. “Ugh!! You big meanie!!” he whined out, getting up and dusting himself off before running ahead of Katsuki, turning around and screaming, “LAST ONE THERE’S THE NUMBER 3 HERO!!!”

Katsuki began to run after the fast teenager, but he caught up, causing Izuku to go faster, and then him until they both got to their middle school in record time. “I obviously won,” Izuku stated proudly, flipping his rather short curly hair. Katsuki rolled his eyes and grabbed Izuku’s head, pushing it gently. “Oh my god. You’re such a dork!” he laughed out. Izuku put his hands on his chest, showing off his bare ring finger. “But I’m your dork~~” Izuku joked, immediately bursting out in laughter after he said it. The pair laughed a bit before heading to their shared class.

“Pfft, we’re both weirdos,” Katsuki said, smiling. Izuku nodded his head in agreement, smiling with him. The two talked and joked a bit with each other until they got to their class and went to their seats. Homeroom was boring and long, mostly boring since the teacher was talking his mouth off about high school. “Bakugo, aren’t you aiming to go to U.A.?” the teacher asked, holding a small stack of papers. Katsuki rolled his eyes and groaned out, “Yeah, of course I am! I’m better than all you wanna-be punk losers! I’m going to be even stronger than All Might and surpass him!!” Izuku laughed a little bit, but no one noticed. The entire class was chatting and buzzing with excitement.

Katsuki looked annoyed, and he was. All he wanted to do at the moment was talk, touch, joke with, and be with Izuku, but school was in the way, and so were people. Katsuki loved being with the greenette, even if it was silence in one of their rooms, he just enjoyed Izuku’s presence. It was one of the very few things that actually calmed him down fully. Izuku, sleep, making jewelry, and spicy food are the only things that can calm the hot-headed blonde down completely. Katsuki has barely ever gotten actually mad at Izuku, it’s only happened a few times, and Katsuki felt super bad afterward.

After the first half of the school day was other, it was lunch. Katsuki and Izuku were walking with each other to get lunch, they both were joking and chatting with each other. “And that’s my reasoning for why I wouldn’t beat his ass,” Izuku said rather proudly. Katsuki rolled his eyes and laughed lightly. “HA, that was only like, two reasons!! And they were, ‘he has a magic scarf’ and ‘he looks buff’, which you continued to add ‘I think I might be gay because of him’ and then said ‘I would let him go full-on Super Smash Bros in bed with me’,” Katsuki said, mocking Izuku. Izuku blushed furiously, covering his red face. “S-SH-SHUT UP!!” Izuku stuttered out, flustered, but then continued, “But exactly. I wouldn’t be beating his ass, he would be beating mine-” “Okay first off, you said it with such a straight face, I’m shocked. Also, bitch both me and you know that he ain’t even know you exist,” Katsuki said, cutting Izuku off for the better. Izuku rolled his eyes and the two continued walking.

The two (obviously gay) teenagers sat outside while they ate their lunch. They weren’t talking at all or anything like that, they weren’t doing anything involving the other. Katsuki stood up and placed his tray down in his spot. “I’ll be back, I’m gonna go to the bathroom real quick. Be good, don’t be too gay while I’m gone, and please god when I come back don’t tell me any sex scene that comes to your head while I was gone,” he said before leaving the troublesome greenette. Izuku was then there without any Katsuki-Supervision, which wasn’t a good thing.

Two people in the same grade as Izuku walked over to him. They had just come out of the building, so they luckily didn’t hear Katsuki’s and Izuku’s two-sentence conversation. “Heh, look, Najoku! It’s the quirkless loser in this school!” the male said, grabbing Izuku’s hair and slamming his head onto the lunch tray in his lap. Izuku winced at the pain spreading fast in his head. The tray got taken out of his hands and then smacked the side of his head, then the rest of his body as the pain spread faster and faster until his whole body was experiencing an undying pain. Izuku didn’t know how many times he got hit with his tray or punched, or even clawed at, he just knew that it fucking hurt and he was about to start a fucking fight if Katsuki hadn’t come back right then in time. “OI!! WHAT THE FUCK ARE YOU DICKWADS DOING?!?!” the comforting voice that Izuku had memorized by heart screamed, scaring the female and male beating Izuku up. The students quickly ran away, not getting caught.

Katsuki ran to Izuku and crouched on the ground, inspecting the wounds. “Heyyyy, Kacchan…” Izuku groaned out, tasting the blood from his bleeding lip. “You’re bleeding. Are you okay? Do you feel okay? You should go to the nurse. I’m going to take you to the nurse, so up you go, idiot,” Katsuki said, worried, but then picked up Izuku bridal style and carried him the whole way to the nurse, not caring who saw them. Izuku swung his legs gently and talked to Katsuki about random things on their way there.

The nurse patched Izuku up, sympathy and pity lacing her words. Once he was done in the nurse’s office, the two childhood friends went to their class, one of them not caring that he was late, and the other panicking. “Kacchan!! We’re late again!!” Izuku whined, panic lacing his every word. Katsuki rolled his eyes. “It’s okay, you have a reason why and a pass. So the teacher should be okay with it,” the blonde said, trying to comfort Izuku. Izuku sighed and nodded his head, then spoke, “Yeah, I guess… But pfft, I’m terrible at fighting back.” Katsuki laughed gently at the sudden mood change. Izuku nodded his head, but then Katsuki spoke, “Ya’know if you want, I might be able to help you and your terrible fighting abilities. I’ll train you, I have a bunch of free time, and so do you. But like, it’s only if you want- Woah why are you crying?!”

Katsuki panicked at the sight of a crying Izuku. Izuku wiped away the pouring tears and said in his most confident voice, “Kacchan, will you train me? Please?” Katsuki blushed lightly, but then answered, “Yes, yes I will, you big dork.”

Train The Gay Stronger

It was a rainy day, Tuesday specifically, and happiness could be heard in the apartment. “Kacchan!! It’s All Might!!” a young greenette squealed with excitement, pointing to the famous hero on the TV.

The blonde smiled widely, then cockily said, “Y’know, when I grow up and become a hero, I’m gonna be even better than All Might!!” Izuku’s eyes sparkled at the statement as he smiled widely. “Waaaah, really, Kacchan?! I mean, you definitely have the quirk suitable for a hero, and with your skills, it wouldn’t be surprising if Kacchan became the best hero!!” Izuku rambled on, getting caught in his own little world- with Katsuki, of course. “Tsk, I’m gonna be the best hero no matter what!!” he boldly said, flexing his nonexistent muscles.

Izuku hummed happily. He then joyfully said with a smile, “And I’m gonna cheer Kacchan on, no matter what!!”

“Eight hundred pushups, now,” the blonde ordered, smirking. The greenette gaped and argued back, “Heyy!! I can’t do that manyyyyy!!! Let me start with like, ten at least!! You know I don’t exercise much!!” Katsuki chuckled and rolled his eyes, looking at the shorter complaining male. “Fine then, I know somewhere we can train. Come on, short stack,” the hothead said, walking away from the weak string bean, who followed him quickly so as not to get left behind. The two ran to where Katsuki was bringing them. Once they finally got to their destination, Izuku was slightly confused but had many ideas for why Katsuki brought him there.

Katsuki sighed, then spoke, “I keep seeing this place when I’m sent to do errands and such. It’ll be perfect for you, plus then people will be able to be on the beach. Who knows, maybe have dates too.” Izuku giggled at that last part, which Katsuki rolled his eyes at.

“Now, you will clean up this entire beach, along with a daily workout and such. Since you need to get stronger first, you will be doing exercise to get more muscle, then we’ll work on fighting styles. But for right now, get to cleaning,” Katsuki explained, plopping on a washing machine. The two boys were at a dirty beach, it was piled with rubbish and trash, all different sizes and weights, and all different things. Izuku nodded his head, feeling the confidence he had in him rush through his body. Izuku walked to part of the rubbish pile and started picking out the smaller things, working up to the larger things. Katsuki watched him, encouraging him the whole time.

After a few hours, it was sunset. Not much progress had been made to the dirty beach, but Izuku would work on it nonetheless. The teenagers walked home together, chatting and discussing the plan they would have for their training. “We both should do workouts together since it’ll help the both of us. You want to go to U.A., right?” Katsuki said, walking beside Izuku. Izuku hummed in response, then put it into words, “Yeah, I would like to go to U.A., but I don’t know if I’ll be accepted or not. But still, it would be good to know how to fight and be strong, just in case!!” Katsuki nodded, making a mental note of his best friend’s comments. Katsuki spoke again, “Well I heard that they use robots for the entrance exam, so we both need to be strong for that. So if we both are training, then we’ll get more experience and might have a better chance of getting in.” Izuku nodded, smiling at how smart the blonde he had known all his life was.

“Yep… Well, I gotta go. Bye, Kacchan, see you tomorrow!!” Izuku said, waving to Katsuki as he walked away. Katsuki gave a small wave while he smiled at how much time he got to spend with the greenette that day, and he would the next day, and so on. The two teenagers walked home safely, nothing bad happening to them on their way there or even there.

Chapter Text

Touch Me. Please.

It was a sunny day, and Katsuki, Izuku, and their friends were in the woods hunting for villains and bugs. Katsuki was crossing a bridge made up of a hallowed out old log with the rest of his crew following him, Izuku being in the back, which only the school friends voted for. Katsuki took a few steps to the middle of the log, then lost his footing and slid off the wooden bridge into the shallow river below them. The water splashed up and around the blonde as he fell in, luckily not hurting himself.

“I’m fine!!” Katsuki called out to the small group above them, smiling proudly. There were a few small splashes of water at the end of the river, coming towards Katsuki. He turned his head to reveal the greenette by him, holding out his hand to help the blonde up. “Do you need help, Kacchan? Can you stand? Are you hurt?” the caring greenette said, making sure his best friend was okay. The blonde looked at the greenette, not answering.

Then, Katsuki grabbed Izuku’s hand and pulled him down into the water with him. Izuku squealed and Katsuki laughed, both having fun. They got out of the river together and back with their group of friends, but this time by each other and holding hands.

It had been a few months since Katsuki and Izuku had started training together, and they’d made quite a bit of progress, both physically and mentally. Their relationship has also improved, growing into a bloom of never dying flowers. They spent more and more time together, improving their fighting styles and strength, their relationship and their diet, and the forever-there feelings for one another-

Katsuki and Izuku were at the beach, like usual when it was after school. The beach was almost fully cleaned up, there were only the heaviest things there, and the washing machine that Katsuki had been sitting on the entirety of the 4 months they had been at that same beach. Izuku was pulling the lockers that held Katsuki on top of it. “Do you have to sit on it while I’m pulling it?” Izuku asked, pouting slightly. The blonde chuckled lightly, then laid on it. “Yep, this is training for you. I’m training my mental state, you’re training your physical… Now get back to work!!” Katsuki said, then spraying water at him, which made the greenette yelp and continue pulling.

Izuku had finished pulling the lockers and then started to walk off, but fell to the ground when something jumped on him, actually, when someone jumped on him. He jumped slightly and grabbed the nearest part of the person’s body, pulling and slamming them into the ground as he pinned them down. Katsuki groaned dramatically but then burst out in laughter. “PFFTTTT, your reaction was hilarious!! But you’re good at pinning someone down, I’ll give you that. And nice with the slamming on the ground, that’ll give you an advantage in the fight, plus the person will be hurt. So 10/10,” Katsuki said proudly, earning a roll of eyes from Izuku and he smiled and sat on top of Katsuki.

“Oh, wow. Thank you soooo much,” Izuku sarcastically said, running his fingers through Katsuki’s hair. Katsuki was fine with Izuku touching him in any way, especially his head since Izuku had done it many times during their childhood and even while they were growing up. Katsuki smiled at the cute greenette that was still sitting on him. “So, you gonna get off anytime so or..?” Katsuki asked, not really caring if the calm male wanted to stay like that or not. Izuku thought a little before replying with, “Hmm, nope. I’m going to stay here for the rest of our lives.” Katsuki laughed gently. “Oh, okay then… Hmm, then I wonder what I’m going to do with that katsudon I planned to get, I just don’t know who li–” “Okay I’ll get off!!” Izuku excitedly said, quickly getting off the blonde.

Katsuki chuckled, then got up with the help of Izuku. The two went to the closest place where katsudon and curry were sold, or at least the ingredients. Then they got them and Katsuki paid for them, earning a bright, warm smile from Izuku, who was basically radiating pure happiness. The two teenagers walked to the park they used to play at as kids. They sat on a bench and ate their food, enjoying the presence of one another.

It seemed like everything was perfect. It was peaceful, the sun was setting, Izuku and Katsuki had each other by them, they were eating good food… It seemed perfect to the two male teenagers.

“Hey, Kacchan?” Izuku said, looking down at his food. Katsuki hummed, signaling for the greenette to continue talking, which he did. “We should live together. Like, when we’re older or even now. I mean, we both have an amazing relationship with each other and then we can split the chores. I can get a job or a way to earn money if U.A. doesn’t work out, or even if it does work out. I mean… I just think it’ll be amazing to live with Kacchan,” he said, smiling slightly. Katsuki quickly swallowed his food but remained quiet for a moment. He cleared his throat and looked at Izuku, his eyes shining. “Midoriya Izuku, I would love the pleasure of living with you. It would truly be an amazing experience. But first, we’d need the permission of our parental units since they need to know how much safety we have. But otherwise, yes, I will live with you if I have the choice… Plus either way, then we both be walking together and wouldn’t have to go to each other’s house when we wanna see each other,” Katsuki said, putting his food away in the bag he got to carry it.

Izuku’s smile widened as he cheered, kicking his feet excitedly. “Yay!! Kacchan would live with me!! I know some good apartments and the rent doesn’t cost too much! They’d be a little bit from middle school and high school, but otherwise, we can make it work!!” Izuku rambled, happiness kicking in. Katsuki smiled and listened to the nerd’s rambling as he quickly put their food back into the bag and stood up, Izuku following his actions and standing up too. The two started walking beside each other. They both were going to their separate houses, talking and joking and holding hands the entire way until they had to go their separate ways.

“Bye, Kacchan!! See you tomorrow!!” Izuku said, smiling happily while waving at his dear best friend. Katsuki smiled and waved back, this time saying, “Bye, see you, shortie.”
