( HhhHhH KACCHANS COMING in the next chapter, hope u guys don't mind this chapter also don't worry, TodoDeku will prevail it's on the title !!! ) ( also Kacchan is 13 while Izuku is 10 so Kacchan already has his growth spurt while little Izuku hadn't had his yet, not that proud of this chapter to be honest to looks too rushed :(  )

_______________

It wasn't long before he and Kacchan started to train the dragon which they named fluffball despite the dragon not having an inch of fur on it, Izuku found the name cute and Izuku had always wanted a dog, so he decided to name it that, Katsuki thought it was stupid but fluffball won't respond unless he is called fluffball leaving Kacchan with no choice but to say that in order to train it

"Y-You know you don't have to train I-It Kacchan-"

"Shut up Deku, if it's going to stay in this village it needs to be trained!" says Kacchan even though the village is littered with untrained dragons

Izuku pouted, Fluffball also pouted

"Aww it's okay Fluffball, you don't have to be sad because I'm sad too!" Izuku said a smile grazing his cute little face, he cupped the baby dragons cheek and gave it a kiss on the nose, the dragon let out a steam on its nose causing Izuku to giggle and Katsuki to scowl

It's been like this ever since, Katsuki waking Izuku at ungodly hours in order to 'train' fluffball which just includes Katsuki ordering him to do tricks while Izuku watched in amazement, maybe ordering a trick or two, after that they'd have a lunch break, Izuku would sit next to Katsuki as Katsuki scowled at anyone who tried to get close, maybe while scowling Izuku will feed him some of his lunch, then they'll go back to watching fluffball do tricks

Then at night Katsuki will drag Izuku back to his mother, pet him roughly ( really roughly ) and if Izuku did really well 'behaving' ( aka not making any smartass comments or being sassy ) Katsuki would kiss his forehead, Izuku would flash him a very nice wide bright smile after and Katsuki would hit him in the head scowling before finally marching away

One time Izuku asked to meet Katsuki's parents, for once Katsuki was panicked and said no you may not meet the ones who has brought me into this world no thank you, that kinda sucked, but knowing Katsuki, he wouldn't want to meet the people who he got his personality from no offense to him but Katsuki kinda sucks personality-wise

He woke up when Katsuki bonked him on the head again, he sat up and clutched unto his head tears forming on his eyes

"What was that for Kacchan?!"

"You were having bad thoughts about me thats why!"

"I was dreaming Kacchan! I can't control it!"

"What's why I woke you up, stupid!"

  "I'm not stupid take that back! It's like 2:00 am  right now did you wake me up just so I won't have bad thoughts about you?!" The guilty look that passes Katsuki's face was enough evidence for Izuku and he pouted before hitting Katsuki gently on the head too

"Hey what was that for?! You wanna fight?!"

"You bonked me on the head! I bonked you back"

"That's not fair!" Izuku whined and flailed his arms around hitting Katsuki a couple of times, Katsuki tried to block but a whining Izuku is surprisingly very strong

"STOP HITTING ME YOU DAMN NERD!" Katsuki yelled before finally managing to grab both of Izuku's arms, stopping then, Izuku let out a whimper

"Kacchan is unfair!"

"You already hit me a couple of times!"

"Wha.. I did?"

"Y-Yeah.." Katsuki said a suspicious red slowly spreading on his face, Izuku looked at him before clapping happily

"Were even now Kacchan yay! Now lets go to sleep it's 3:00 am in the morning"

"W-What?! I'm not going to sleep with you- grck?!" Katsuki was silenced when Izuku promptly pulled him down on the bed with him and covered his mouth

"Shhh, were yelling too much mama is still sleeping, if you try to leave you'll cause a lot of noise!" He said in a whisper

Not that Katsuki could answer, the hand is still covering him as he was reduced to a body pillow by little Izuku who started cuddling up to him, he was too shocked and dumbfounded to try to escape so he just tried to sleep again

"Good night Kacchan"

"Night, nerd"

______

Katsuki can't fall asleep, the small body right next to him was proving to be a distraction despite it staying still, maybe it's the small arms wrapped around him proving to be a distraction and for some reason he suddenly has this huge urge to set the small child on fire just to see how he would react but Izuku will most likely cling unto him causing him to set on fire too, sure he's immune to fire but his clothes sure aren't

He watched as Izuku's chest rise up and down to breath he had a morbid thought of pushing down on it causing Izuku to struggle for his breath

Katsuki should sleep he's getting weird morbid thoughts

But still, he found Izuku too mesmerizing, it's his first time seeing his body close up, he can't help but feel a bit weirded out by himself due to how much he was staring but it's not his fault, he gently cupped the boys cheeks before squishing them together like a toy

"Mhmm K-Kacchan go back to sleep!" The boy murmured out, Katsuki stopped and continued to stare, Izuku latched unto his arm now, he wasn't sure how to feel about it

Should he pull him off or...?

"Kacchan I said go back to sleep!" Izuku whined

Right he should sleep, think later please the small kid first

He hesitantly wrapped his arms around Izuku and rested his chin on his head, still wide awake

Since when was sleeping hard damnit?!

"K-Kacchan you're squeezing me!" Izuku whined

Ugh Izuku is so whiny, he loosened his grip a little until Izuku hummed in satisfaction

"You can't sleep Kacchan?"

"What made you think that, is it because my eyes are wide open and I'm annoying you"

"Kacchan!"

"Okay fine sorry, but yeah I can't sleep"

"Me too, you're fun to have around Kacchan I can't sleep"

"All were doing is lying on bed trying to sleep, there's nothing fun about it" Katsuki slowly pulled away to look at Izuku's face

"But you're here doing it with me! I-It's fun that way Kacchan" Katsuki's eyes widened at the red on Izuku's face

Oh shit

"Shut up and sleep already!" He pulled Izuku unto his chest and he buried his face in Izuku's hair

_______________

He only woke up again when he heard cooing noises, he gently pushed Izuku off himself and sat up to see Izuku's mother who took a picture of them

"You're early today Katsuki-kun, what do you want for breakfast"

"I'll have whatever, it's fine your cooking is good no matter what it is"

"Oh you're such a charmer! Okay I'll cook the usual is that fine?" Katsuki grunted and Inko took it as a yes and left the room, Katsuki shook Izuku and the green haired child woke up

"We're gonna go to fluffball Kacchan?"

"Yeah" Katsuki stood up and took Izuku's clothes from his drawer before throwing it to him

"Aren't we gonna take a bath first Kacchan?"

"I'm clean, you have drool all over your face" Izuku pouted and went to the bathroom with the clothes while Katsuki waited, after a couple of minutes Izuku came out with hair extra fluffier and cleaner than before and wearing clean clothes instead of pajamas, Katsuki lifted him up and Izuku latched himself to his neck and proceeded to sleep again

Katsuki carefully went down the stairs making sure Izuku won't fall or something before shaking him awake to eat again

"You two are so cute, you should come here early more often Katsuki-kun!"

"Yes you should Kacchan! I like having you around a lot!" Izuku said a bright cute smile spread in his face, Katsuki scowled and shoved a spoon full of rice in his mouth

"Eat more talk less nerd" Izuku happily nodded and went back to eating, after they ate Katsuki dragged Izuku to fluffball ( who's just outside the house ) and plopped him on top of the dragon

"Hey fluffball,  wake Deku up"

"W-What?" Was Izuku's last words before Fluffball readied his wings and shot up in the air, if you listen closely you'll hear a screaming Izuku pleading for his life

After three minutes the dragon went down

"Are you awake now"

"Y-Yes" was Izuku's last words before falling off fluffball and trying to wiggle like a worm into the ground, Katsuki pulled him up before he actually got down though

"K-Kacchan what did you teach fluffball! You're a horrible parent!"

"Tche, it worked didn't it?! And I'm not a horrible parent I'm not even a parent" Izuku whined and hit Kacchan in the where it hurts the most then ran to fluffball and sobbed unto his scales

"Fluffbaaaall don't ever ever follow Kacchan again he's horrible influence to you!"

"Rawr!"

"Don't worry I'll find you another daddy"

"RAWR!"

"Your daddy is bad influence!"

"Rawr?"

"Yes bad influence okay? Never ever listen to him again or else I'll get upset!" Fluffball nodded and licked Izuku tears off immediately lifting Izukus mood up, he was so happy that he didn't notice Kacchan crawling unto him and grabbing him by the foot sending him to the ground

"Ouch! What the heck Kacchan?!" Izuku whined, he was flipped over and Katsuki crawled on top of him and with both of his arms pressured Izukus head unto the ground

"MMFFM MMMMFM" ( translation : WHAT IS GOING ON SOMEONE HELP ME )

"No one is going to hear your cries Izuku, you WILL DIE HERE INFRONT OF YOUR BELOVED PET"

"MMHMMM MFFMM MMM" ( KACCHAN LET ME GO IT WILL BE HARD FOR YOU TO BE A SINGLE PARENT LET ME GO )

"I can take care of fluffball by myself! Die you butt!"  He says but after a few minutes he rolled off Izuku and Izuku shot up and breathed in as much hair as he could

"You're lucky that it's all grass there, there's not much dirt on your face"

"I think your face IS dirt Kacchan! That was mean I could've died!"

"Well you didn't, did you? Stop complaining nerd you're the one who kicked me in the d***"

"You said a bad word!"

"Hell yeah I did"

"YOU DID IT AGAIN! IM TELLING MOM"

"WAIT NO GET BACK HERE YOU LITTLE SHI-"

"MOM KACCHAN IS SWEARING AGAIN!"

____________

And so Katsuki was forced to babysit Izuku AGAIN as compensation

"Kacchan can you get hand me a pillow"

"Get it yourself nerd"

"MOM-"

"Okay fine here have your damn pillow!" Katsuki scowled handing Izuku the goddamn pillow, the green haired child squealed in delight and hugged the pillow close to his chest

"Thank you Kacchan I love you!" He said red spreading to his face, Katsuki scowled and hit Izukus face with a  pillow, he doesn't want to see that face, Izuku shouldn't be feeling for him

Katsuki just can't help but feel guilty because he probably won't be able to return Izuku's feelings, he was like a big brother to him and it's just weird

He sighed and lifted Izuku up and placed him on his lap before placing his chin on top of the boy

"Anything else you want, Izuku?"

"Mhmm, nothing else Kacchan you're here with me and I have a pillow! Two of the best things I can have!"

"Sure, 'm happy too" Katsuki said lazily

"Hey Izuku?"

"What is it Kacchan?"

"Why do you like me? As far as I know, I tease you a lot, also beat you up a lot, my nickname for you means useless and I like yelling at you, so why?"

Izuku sat there contemplating what he should say before he turned around with a bright grin on his face

"Because your Kacchan!"

"Because I'm Kacchan?" Katsuki rose a brow at that

"Kacchan has always been this person on the top who I really wanted to be..."

"But you don't like violence, and everything I do includes a bit of violence in it"

"I know Kacchan, but when I got to know you, I realized that I really didn't want to be like Kacchan... because he's too violent, too rude, too demanded, too bossy and a lot of other bad stuff"

"So why?"

"I don't know Kacchan, I can't explain it that well but whenever I'm with Kacchan, I just feel happy and giddy and all that good stuff, I don't want to be in top like Kacchan, I just want to be with Kacchan because no matter what he does he always makes me happy"

"That's a long explanation Izuku, summarize it"

"I love Kacchan and I want to be with Kacchan!"

"Mhmm" Katsuki patted Izukus hair and placed a kiss on his forehead

"It'll be nice if that can happen 'zuku, thanks for explaining"

"You're welcome Kacchan!" The child gave him a happy grin before hugging him

"Izuku?"

"Yes Kacchan?"

"I love you" Izuku stared at Kacchan for a few moments before his face turns bright red and he covers it with his hands

"Seriously? You said all that stuff about me and now is the time that you get flustered" Katsuki held back the urge to laugh

"Ts not my fault Kacchan! Don't say it so suddenly like that I'm not prepared!"

"Whatever Deku, lets go to sleep"

Izuku grumbled but complied anyways

_________ time skip _________

"Izuku?"

"Yes Kacchan?"

"Do you really have to leave? You can just stay here and work here instead"

"Kacchan I told you before, it's either me or mom who's going there, I'd rather go there than send my mom to her death"

"You don't have to my family will protect you-"

"Katsuki"

Katsuki looked away, a scorn marking his features, he just doesn't want Izuku to go there, what if he doesn't return what if he finds that place better than here? What is he going to do? And he can't just tell Izuku who his parents are, Izuku won't trust him after hiding a secret as big as that from him for more than 5 years, it's too much

"Kacchan, listen, I want to stay here myself-"

"Then stay! Don't go out there you know Inko would rather go in your place, you have so much to live for Izuku, your mom only lives for you now you don't have to-

"Kacchan! I told you I've made up my mind I'm going I'm not sending my mom there! Please don't make this harder than it already is Kacchan! I'm leaving don't try to stop me again"

Damnit why won't he just listen?!

Katsuki clenched his fist and reached for Izuku's hand only for it to be slapped away

"Izuku fluffball will miss you-

"Kacchan that won't work anymore"

"Izuku-"

"Good bye Kacchan, take care of mom for me"

____________

Katsuki watched as Izuku said good bye to everyone for the last time, a hug and a kiss to the cheek, maybe a charm to give out protection and good luck- it didn't matter Izuku shouldn't be going there in the first place he'll die there but he's letting it happen because he's a damn coward

"Kacchan?"

Katsuki snapped out of his thoughts

"Yes?"

"I'm sorry for snapping at you earlier, I didn't mean to.." he shouldn't be it was Katsuki's fault, Izuku had his mother since he was little, she took care of him as much as she could, bought him all the things he wanted ( which were not that many ) no matter the price, it was his fault thinking Izuku would just let the person who took care of him there

"It's okay I'm sorry too... I must've looked like an insensitive jerk"

Izuku hugged him, he returned it back, for once tears were falling from his eyes, he hugged the smaller male hard

"Hey Izuku, if I don't let you go right now would you still leave?"

"Kacchan..." slowly Izuku tried to get out of Katsuki's grasp

"I don't want to let go Izuku, stay with me please-"

"LINE UP THOSE WHO ARE STILL THERE, TIME IS UP LINE UP"

"Kacchan I have to go, please"

Katsuki hesitantly pulled back and kissed Izuku's forehead one last time

"I'll miss you" Izuku smiled

"Me too Kacchan, I love you!"

"I love you too" those were Katsuki's last words to him as he watched the green haired male sail off

______________
Srry for the amnt of timeskips rip just to give context too, there was a war going in the Endevirr kingdom ( Shoto's kingdom ) and every single household should give up one person to fight in the war because the war was so bad that they need fodder to weaken the enemies, Izuku is 14 Kacchan is 17 in that part, maybe I'll redo this chapter or something it's bad :c
