Work Text:
Izuku hummed to the beat of the music playing from his headphones, tapping the pencil against his homework on the desk.
Kacchan must still be in detention right now. It’s the third time he had gotten it this month, but Izuku had to admit this time it was actually unfair.
Mostly because it had been Izuku’s fault.
Katsuki had established a silent rule around the school that no one ever questioned: he was the only one who could mess with Izuku. No one else in school dared to even look his way for too long, and Izuku honestly couldn't complain. He didn't exactly dislike it.
But yesterday, some senior students decided to corner Izuku after gym class when the teacher had already left.
Izuku guessed that's how nature worked. He was small, scrawny, and innocent-looking. Basically, the description of what a prey was in a dictionary. So the bigger, stronger kids looked down on him with savage satisfaction in their eyes. He was lucky everyone respected (or feared) Kacchan enough not to mess with him on a daily basis, but apparently, those guys felt brave that day.
And what a mistake.
Izuku whimpered when his body hit the floor.
He tried to fight back; he always did. Izuku always went down swinging. But they only laughed.
“Aw, you think you can fight, little guy?” One of them mocked. “Don't make me laugh.”
“We should drag him to the back,” the other said with a sick amusement. “So no one interrupts our fun.”
The third one cracked his knuckles. “You think you're so tough because your guard dog Bakugou has your back?”
Izuku recognized that guy. He and Kacchan had gotten into a fight last week.
Kacchan came out clean, but the guy still had a black eye.
Ah, so that's why they're after him, because they’re cowards who can't win against Kacchan, so they're taking it out on Izuku instead.
“He's not fucking here now, is he?” the guy asked with a heinous grin. He leaned down, menacing and clearly trying to intimidate him, “And if you dare to tell him a word about this to him, we’ll make sure that you-”
The guy didn't get a chance to finish what he was saying because a blur of blonde hair and a black uniform tackled him to the ground.
“Kacchan!” Izuku gasped.
Katsuki didn't listen. He grabbed the guy by the neck of his uniform and slammed him into the floor with enough force to make the wood under their feet vibrate.
“Why don't you mess with someone your own size, asshole?” Katsuki snarled at his face.
Kacchan looked scary like that, with his eyes scorching red and his lip curled into a vicious snarl, showing his sharp canines as his fist tightened around the other guy's shirt.
The guy was frozen in terror.
“We weren't-” he stuttered.
“Not so brave now, huh?” Kacchan spat. “You're pathetic.”
Katsuki was livid. And boy, if Izuku was the one on the other side of his anger, he'd look like he's about to piss his pants too.
“If you touch him again, I will make sure you never use your hands again,” Katsuki said with a deadly voice, looking straight into the guy's terrified eyes. He pressed his foot onto the guy's hand splayed on the ground beside them, and Izuku winced when he heard a cracking noise. “For now, I'll just break them a little,” Katsuki grinned.
The guy cried out in pain, and his friends tried to step in, but Katsuki was faster. Better. Smarter.
Three against one.
And Katsuki still won the fight.
It was over quickly. Kacchan swept the floor with them and barely got a scratch in return; Izuku nearly felt bad for the other guys who clearly never stood a chance.
Katsuki was sweaty and short of breath when he knocked the last of them off, cheeks flushed with exertion. Izuku made a small sound of relief, and caused red eyes to narrow on him where he had been thrown, still on the floor. Katsuki’s eyes visibly softened.
“Nerd,” was all Kacchan said when he helped Izuku up.
“You didn't have to do that, Kacchan,” Izuku quietly said, twisting the fabric of his shorts.
Katsuki scoffed. “Don’t have to do shit, Deku. But I wasn't going to let those idiots think they could get away with hurting you.”
Izuku couldn't keep down the smile that crept up his face as he stared at Katsuki with glinting eyes. Kacchan stared back for a moment before clicking his tongue and looking away, the tips of his ears turning red.
But of course, that was the moment in which a teacher came crashing through the door, probably alerted by another student about the fight unraveling inside the gym. The teacher took one look at Katsuki, then at Izuku, and then at the guys whining and groaning on the floor.
The teacher sighed, pinching the bridge of her nose. “To the principal's office, Bakugou. Now.”
"Sensei,” Izuku rushed to plead, “It wasn't Kacchan’s fault! They were pushing me around and-”
“Don’t want to hear it this time, Midoriya,” The teacher cut in. “They're going to the principal's office too, but first they have to be checked by the nurse.”
“But-”
“Do you want to go with them?” the teacher snapped.
“Leave it, nerd,” Katsuki said. nonchalantly strolling towards the teacher, with his bloody knuckles hidden inside his pockets, “Don't get your ass in trouble for no reason. I'll be fine.”
Katsuki reached the door, which the teacher was angrily holding open, and threw a glance above his shoulder at Izuku. He was smirking.
“Go home.”
Izuku deflated and nodded, defeated.
Kacchan wasn't considered a little delinquent by everyone for nothing. He was used to this. It's not that he went around committing crimes or anything, but he had a bit of a problem with submitting to authority figures and following rules he thought were stupid. Which were most of them, really, but Izuku didn't exactly disagree with him; he just never had the personality to do something about it.
Izuku had always believed Kacchan was the coolest in the whole world.
They had their differences over the years, but by some stroke of luck, they ended up working together on a group project back when the year started. Kacchan might have been a troublemaker, but he was still the top of their class (probably the best in their entire middle school, which only made things more infuriating for the teachers). And during those long hours they spent working together, their friendship blossomed back to life somehow. And well, their relationship might have taken a little unexpected turn, as well…
Izuku was smiling like a fool before he realized, biting his lip and dreamily looking up to the shelf above his desk. The picture of Kacchan and him in the park when they were children, missing teeth in their eager smiles, stared back at him, and his chest grew fond.
Who would've thought, huh? After all this time…
Clink!
The sound against his window startled him. he took his headphones off, frowning. What on earth?
Clink! Clink!
Izuku stood up from his chair and beelined for the window. He threw the curtains open and squeaked when he found Katsuki behind the glass.
“Kacchan!” he whisper-yelled as soon as he opened the window. “What are you doing here? You're supposed to be in detention!”
“Got bored,” is all Katsuki said, shrugging.
“You're gonna get in so much trouble if-”
“Relax, nerd,” he laughed, “what’s one more?”
“But Kacchan,” Izuku pouted. “I don’t like that you're grounded all the time. At home and school!”
“And what’s with you, huh?” Katsuki teasingly replied, resting his arms on the window frame as if he didn't just climb up the balcony like it was nothing.
“I-” Izuku pursed his lips, feeling his cheeks heating up, “I can't see you if you're always grounded,” that made Katsuki’s teasing grin stretch wider.
“You're seeing me right now.”
“You know what I mean!”
“So you missed me?” Katsuki said, resting his cheek on his hand as he stared straight into Izuku’s green eyes.
Izuku had to make an effort not to avert his gaze, so he focused on the bruises on Katsuki’s knuckles instead. The boy took Katsuki's injured hand in between his own, carefully rubbing his thumb over his knuckles with a tenderness that would melt anyone’s heart.
“I always miss Kacchan,” he muttered, almost shyly, but terribly honest.
That seemed to disarm Katsuki’s whole suave façade for a moment. His grin disappeared to be replaced by a small smile, almost imperceptible, but undeniably there. His sharp eyes became soft, as they always did when they stared at Izuku, lately.
“Why do you think I'm here, dumbass?” he grunted, doing a horrible job of not seeming flustered. Izuku blinked at him, hopeful, and after a pause, Katsuki finally relented. “I missed you, too, nerd.”
Izuku gasped in delight, although he was not really surprised, but rather touched by Katsuki’s unusual sincerity. He didn't even register that he had started to lean closer to the blond, but Katsuki had.
Izuku licked his plump lips when Katsuki's eyes lowered to them and lingered for a few long seconds before coming back up. Katsuki's other hand came to cradle Izuku by the back of the neck when he got close enough, and then, without making him wait any further because he was just as zealous, he closed the distance between them.
They hadn't kissed many times yet, but every time felt like the first.
Izuku's belly turned, fluttering wildly, and he almost started shaking before finally melting in Katsuki's hold. Katsuki had no experience either, but he was, unsurprisingly, a very fast learner.
He learned that Izuku liked it when he tilted his head to the side and used his tongue to gently explore his mouth, making the kiss slow and wet. He loved when his fingers scratched his scalp, and his other hand held his jaw, leading the pace and making Izuku feel like he was at his mercy. Izuku chased after him when he pulled away to leave little gentle kisses in between the hungry ones. Katsuki sucked on his bottom lip to appease him.
Izuku whined against his lips, and Katsuki smiled.
“You're so loud,” Katsuki said, pecking the corner of Izuku's mouth.
“It's your —peck— fault —peck—,” Izuku replied, now giggling.
“Yeah?” Katsuki teased, voice hoarse and eyes half-lidded.
“Yeah.”
Izuku was drunk in love. He felt like he could lift off the ground and start floating at any second when Kacchan kissed him and looked at him like that. He wished they could stay here, like that, forever and-
Someone cleared their throat behind them, and they both stiffened.
Katsuki's eyes slowly moved to watch who was behind Izuku, and Izuku could swear he could see the color drain from his face. Izuku, unfortunately, didn't have to look to know.
“Good afternoon, Katsuki,” Inko greeted in a flat voice.
Slowly, Izuku turned on his heels to find his mother standing by the door with her arms crossed over her chest and an unimpressed look on her face.
“Mom,” he said nervously, brain not functioning to come up with an excuse that fast.
She ignored him to glare at Katsuki. “While it's lovely to have you, I would appreciate it if you used the front door from time to time,” she continued, her house slipper tapping impatiently against the floor.
“Yes Midoriya-san,” Katsuki quickly replied, spine straightening and taking a step back from her son to set a respectable distance (as if his tongue wasn't in his mouth a second ago).
Inko wanted to laugh at the sudden formality. She had practically raised this child, but she guessed it was too funny not to milk the situation for all that was worth.
“I'm afraid that if the neighbors call me again, saying someone is trying to break into the house through my son’s balcony, I'm gonna be very embarrassed."
“Sorry, Auntie,” Katsuki sheepishly said. Izuku had rarely ever seen Katsuki look this embarrassed; he could practically see a metaphorical tail hiding between his legs. It was so cute.
Inko sighed loudly. “You could get hurt, and I don't wanna have to call your mother and tell her you fell from the second floor, okay?” Katsuki nodded, and Izuku had to resist the urge to snicker because he looked like a kicked puppy being reprimanded.
“Mom, please,” Izuku interceded, having mercy on Kacchan.
Inko lifted one of her hands. “I'm the mom, someone's gotta make sure you kids are safe.” She glanced at Katsuki with her eyebrows raised and a small smile. “Are you saying for dinner?”
Katsuki's face lit up, relief painting his features. “Of course.”
“Wonderful. Come downstairs in fifteen minutes and help me set the table,” she instructed, back to her usual sweet self.
Before she turned around to leave, she pointed at the two of them and squinted.
“No funny business, the walls have eyes.”
“Yes, mom,” Izuku groaned, sending Katsuki an apologetic look.
“Alright, sweetie,” she beamed, smoothing her hands down her apron. “And for the love of God, Katsuki, come inside the house; there is no reason for you to be freezing out there.”
Katsuki practically jumped inside.
Inko gave them an approving hum. “Much better.”
She then left the room, leaving two awkward teenagers whose raging hormones had died down at the hands of an all-knowing mother.
Katsuki could be a rascal, but even he didn’t dare to disrespect Midoriya Inko.
She liked him. He was a bit of a sassy teenager with a volatile temper and too much critical thinking ability for his age, but he wasn't a bad kid. He was smart and hardworking, and most importantly, he'd always been head over heels for Izuku. She could tell he would grow to be devilishly handsome, too; he had the face and bone structure of his mother.
“He'll make a good son-in-law one day,” she mused to herself as she stirred the fried vegetables in the pan, satisfied with herself. She had already approved of him, and Izuku knew it, but playing the helicopter parent was too entertaining for her to pass up the opportunity.
She could keep it up a few years longer; hopefully, they will laugh about it in the future when they remember how much of a punk Katsuki was in his younger years, and how he ended up falling for her baby, the most adorable and sweet boy in town.
