Shouto was walking down a silent hall. Unbeknownst to him, Izuku was walking up the hall just a bit ahead of him. Little did Izuku or Shouto know that the combination of Shouto's boredom and Izuku's existential need to help everyone in sight was about to cause an all out war between Katsuki, Shouto, and Hitoshi.

Unoccupied by anything, Shouto's thoughts decided it was time to torment him. Specifically, with the memories of two day ago. Even more specifically, the thoughts of Katsuki's mouth against his hand, his kindness directed towards Shouto, his body pressed up against his own, and the most beautiful smile he has ever seen.

Nobody had ever been that nice to him before. Well, some people weren't exactly mean, but he knew they were laughing in their heads. Katsuki was probably the first person to outright tell him he was smart. In fact, Shouto was usually dubbed dumb by his peers due to him not knowing much about the outside world and his way of automatically taking things literally. It wasn't his fault that for years he hadn't been in touch with the world. His father had made him train morning, day, and night. Shouto thinks he should have gotten a free pass from knowing all these terms people keep throwing out and knowing things people do that mean something else. Katsuki was the first person to acknowledge that. Or at least, he put down his guard for a second to let Shouto in and apologize.

If you thought Katsuki's eyes were pretty, you'd be even more blown away by Katsuki's smile. A true smile would have Katsuki's eyes sparkling and the way his lips curved upwards, not showing his pearly white teeth. Katsuki probably could slay people with his smile. It brought out those dazzling eyes more than they normally pop out.

Speaking of lips, Katsuki's were warm, thin, and dry. Shouto wanted them against his own. Ignore that last thought. His body was like a god's. Toned muscles wrapping around his waist in a hug. It felt good. Shouto knew he shouldn't be thinking such things about his competitor for Izuku's heart. Or in general, any alphas.

Now, Shouto knew those people blabbering about how alphas can't be together in a romantic relationship were spitting bullshit, but it got to his head.

A sound of something falling to the ground then a soft whine interrupted his thought process. It sounded like Izuku.

Shouto jogged toward the source of the sound to find a few books on the ground next to Izuku who was carrying a mountain of books and struggling to pick up the ones that fell. Shouto knew that Izuku could carry all the books, but that doesn't mean it would be easy. From where this was going, Izuku was going to accidentally drop the rest of the book in the process of getting the few that fell on the ground. Shouto was going to be his savior from that fate.

He trotted up to the greenette and said, "Would you like help?"

"Um, thanks, I think I can do it, Shou. Thanks for offering, you're so nice," Izuku said while blatantly contradicting what he just said. He most definitely couldn't do it.

Shouto smiled fondly and blushed a bit, but he had to stay on track. Shouto hummed, "I don't think that's true. You're practically carrying an avalanche of books. Why do you even have these?"

Izuku gave one of his heartwarming and amazing smiles, "Aizawa-sensei asked me to bring these to the teacher's lounge."

"Let me help," Shouto said as he took the books off the ground and grabbed half of the books off the stack Izuku was balancing.

"Shou," Izuku whined. "You already help me so much. I really don't deserve this kindness."

Shouto felt like pulling out his power point presentation on why Izuku deserved the world and the planets surrounding it, but that might take a few hours and he didn't want to bore the omega so he settled on shaking his head no.

The pair peacefully took the books to the teacher's lounge. One more point for me, and Katsuki didn't even come close this time, Shouto thought.

At least that's what Shouto thought until Aizawa made them do a group project in class the next day. Let's just say, Katsuki was less than happy with Shouto's sudden surge in point keeping.

Let the war begin, Katsuki thought.

Katsuki was chilling with his feet on top of his desk chewing pink bubble gum. Deku was mumbling up a storm behind him. Frankly, he wasn't even paying attention, he was focusing on how to get back at Half-n-Half. He snuck a glance at Deku who was furiously scribbling down shit in that notebook of his.

But that's when he heard it. An introvert's worst nightmare. A group project. An in-class group project to be more specific. Katsuki thinks Aizawa hates them. He's an introvert himself, yes? Then why torchure them with something he hates himself. He should stand up for the introverts. Katsuki thought, well, he's Aizawa. He probably lives off our suffering.

Aizawa quickly listed off his five groups. Katsuki got lucky. His group consisted of Deku, Hagakure, Jirou, and himself. Candy Cane wasn't in it and Deku was. The gods must be on his side.

Katsuki then thought of the possibility this opened up. At the speed of light, he jerked around to see Deku beginning to move his desk to their group. Then, (and he swears he wasn't showing off his muscles to Deku) with one big swoop he picked up Deku's desk, careful not to knock anything off it. With one arm, he moved it over to their group. Deku made adorable sounds of protest the whole while.

It was the perfect come back, Candy Cane helped carry Deku's books and Katsuki picked up his desk for him.

When he briefly glanced at Shouto, he saw him glaring. Katsuki stuck his tongue out and gave him the middle finger like the mature man he was.

Katsuki might have one this battle, but he most definitely hasn't won the war, Shouto thought, mostly to reassure himself. Also, Katsuki has great biceps.

It was Saturday morning, and Shouto was still in his pajamas on his way to get soba for breakfast. He heard the sound of a vacuum and he yawned.

What he was not expecting was a very delicious looking Izuku vacuuming the common room for them. Maybe if Shouto asked nicely, Izuku would let Shouto eat him. From what he heard, it sounded like he had put on the laundry for them too. Izuku had a habit of doing everybody's chores.

Shouto walked over, getting the ingredients for soba out. Which was really just water, a microwave, and the noodles. While warming, he saw Izuku struggling to reach under the couch with the vacuum whilst holding the couch up with one hand. If Izuku wasn't careful he could get his head crushed. Shouto simply could not have that happening.

He walked over and picked up the couch for Izuku. Izuku looked up, for the first time that day, noticing him.

"U-um, thanks, Shouto. You really didn't have to do that," Izuku stuttered, not making eye contact.

Shouto responded, "Nonsense, I wouldn't want your pretty little head to get damaged."

Izuku blushed at the comment. He continued vacuuming. Achievement unlocked: make subject blush.

Then Shouto heard the twist of a key in a door handle. Out stepped Katsuki Bakugou, covered in sweat from a run. He was staring and doing that adorable growling at Shouto.

Katsuki was all sweaty and his hair was tousled thanks to the wind. The sweat made his shirt stick to his chest, showing off his toned abdominal muscles. Due to his mouth being open while his lungs begged for air Shouto got a good look at those pretty fangs. Shouto thought about how it would feel to be bitten with those sharp teeth. Shouto almost moaned.

And damn was Izuku lucky Shouto didn't drop the couch on his head because Katsuki was hot as fuck.

Okay, was Katsuki a little proud he made Shouto practically drool at his sweaty form? Yes. But that was only because of an alpha's sense of competition. His inner alpha must think he won or something.

Also, was he angry because the slimy bastard had one upped him again? Yes again. But that only meant Katsuki had to wait for another opportunity to beat Shouto's ass at this competition.

And that perfect chance arose when he, Shouto, and Deku entered an elevator.

It was pretty normal. Well, probably not for Deku. Shouto and Katsuki were arguing over who would be able to make a better blanket fort. It all started after Deku mentioned a movie he and some of the class watched. Mina and Eijiro had been building a blanket fort.

In Katsuki's defense, Shouto started it, "I think I could build a better blanket fort than Katsuki."

Katsuki turned to Shouto, "What are you talking about stupid Icyhot? Mine would beat yours in five seconds."

Deku giggled, "Blanket forts can't move, Kacchan."

Katsuki's ego grew about ten times the size. If he had a tail, it would be wagging, "Well, mine can. That's how great it is."

"Back on topic, you wouldn't be able to put the patients in for it," Shouto huffed.

"Well, if it was for Deku I could. After all, it would be fit for royalty," Katsuki not so subtle-y flirted.

"Maybe we should test this theory."

"Fine, blanket fort building contest at six in the common room tonight. Mine's better."

"We haven't even started."

"Guys-" Deku was interrupted by a huge shake and a large sound. The elevator had stopped, but hadn't opened. Deku looked around. "It says we're on our floor."

"So we should call for help," Shouto suggested.

Then Katsuki was blessed with his amazing idea on how to impress Deku. "Move aside, extras."

Unable to stop the coming freight train of problems, Shouto hid Deku behind him.

From behind Shouto, Deku peeked at the blonde, "Um, Kacchan, what are you doing?"

Katsuki grinned and readied the attack. He was careful to aim the blow in a way that the debris would not touch Shouto and Deku. He heated his hands and soon enough there was a large, scorching hot hole in the elevator doors. He turned to Shouto to check if he was safe. As if seeing it in his eyes, Shouto nodded.

"Okay, we should be safe. You guys go through first," Katsuki said.

"You most certainly aren't safe," Aizawa said, rounding the corner. "In fact, I will make sure you guys come close to death in training tomorrow."

Aizawa had been true to his word, despite both Shouto and Katsuki offering to replace the elevator door. When they found that approach fruitless, they both tried to plead Izuku's innocence. That did not help. In training, Izuku had broken his ankle, which he hadn't done in eons.

That is where we are now. The morning after training. Shouto came out in his pajamas again, hoping that he could help Izuku with the chores he always tasked upon himself. Shouto thought maybe someone had managed to get him to stop, considering his ankle was broken. There was no sign of the green haired omega anywhere. That made Shouto happy, Izuku was finally getting a break.

He peacefully warmed up some soba and ate it at the table. A few of his fellow classmates came down, they buzzed with the air of tiredness. At around five o'clock in the morning, Katsuki came in all sweaty again. Shouto tried to avoid looking at him. He would rather not be caught looking at another alpha. He did not want his classmates getting the wrong idea, though he knew they would be accepting. He did not have a crush on Katsuki Bakugou. He liked the sweet omega, Izuku.

Katsuki seemed to not like this because he kept trying to get in Shouto's line of sight. He'd bend down in weird poses to show off his ass. That definitely did not make Shouto's face turn red as a tomato. Eventually, Katsuki had given up on being semi-discrete and sauntered right on up to the dual haired alpha. Shouto looked at his soba remorsefully. All he wanted was to peacefully eat his soba. Instead, he has an alpha shoving it in his face that Shouto thinks Katsuki's hot as fuck.

While Katsuki talked, making sure his glistening fangs were showing, Shouto tried to make it not obvious he was looking at Katsuki's ass. Though, he was pretty sure the volatile blonde had noticed. It had made him grin in victory. Katsuki was in a position kinda like this: •--l, leaning on the table.

"Hitoshiiiiii," a voice whined, interrupting Katsuki's speal about the spicy foods his 'Old Hag' made. He was telling Shouto how much better he could make it. Shouto was annoyed at first at whoever felt like being that loud, he was quite enjoying this one-sided conversation with Katsuki, but when he saw who the voice belonged to, he was unable to be mad. "Put me down," Izuku said, kicking playfully into the air.

He was being carried bridal style by Hitoshi Shinsou, Izuku leaning into the purple haired alpha's collar. Despite the protests, he seemed to enjoy the treatment greatly.

"Never. Besides, you deserve to take a break anyways. You've earned it. Plus, I enjoy having you in my arms like this," Shinsou said, kissing Izuku's forehead. The girl's all erupted into fits of coos and Izuku's face turned completely red. Shouto thought this was a risky move for 'just friends'.

Katsuki and Shouto stared blankly at Shinsou. He had definitely won this war, but there would be many more to come before the victory. Shinsou turned to Shouto and Katsuki from the other side of the common room, still holding Izuku and stuck his tongue out at them. He made sure Izuku didn't see.

Katsuki and Shouto had another competitor for the battle of Izuku's affection and he was sure going to be tough to beat.
