Hear me out -

Omega katsuki, a dragon born who was in love with his dragon kirishima. While they were both deeply in love, the war forced mitsuki to marry katsuki off with the new heir of All might's kingdom, Izuku midoriya

Katsuki hated the marriage but he knew his
2
People couldn't survive the war without alliance, so he agreed

Katsuki hated his new life, he hated his tight clothes, hated his countless etiquettes, hated all the nobles and he also want to fucking hate his marriage but Izuku just makes it so fucking difficult
3
Izuku gave him respect

Izuku learnt katsuki's language before katsuki could know what Izuku even speaks, Izuku greets katsuki on the table everyday with flowers he himself picked from the garden. When katsuki throws that away, Izuku simply takes it as a invitation to present
4
Different kinds of flowers. Izuku personally instructed the cooks to match katsuki's taste buds and even though katsuki never fucking gave any kind of encouragement or feedback, Izuku had figured out almost all of katsuki's favourites and jolted down notes on them for the cooks
5
Nobody in the castle have treated katsuki with so much respect and given him so much political presence and power that it's almost impossible for katsuki to hate Izuku even though that's all katsuki wants to do

Exactly one month into the marriage, Izuku knocked on katsuki's
6
Room for the first time. Izuku had never ever entered blond's nest so katsuki had allowed him in, knowing it might be matter of urgency

Izuku was holding a herbal mix. He explained to katsuki that the nobles were pressurising him for an heir for long but recently even
7
Queen mitsuki had sent a personal latter saying if Izuku wanted to finalize the marriage or not

After all katsuki wasn't marked, neither is he carrying izuku's child like he was fucking supposed to

Izuku humbly asked if he would allow Izuku to mate him with
8
Katsuki scoffed. He had been prepared to endure this on the first night of the marriage. But instead the alpha had given him space as long as it was possible

Katsuki agreed, grumbling they should get on with it

Izuku looked nervous and anxious. He removed his clothes and folded
9
Them neatly on the counter, asking katsuki if he had preference or anything Izuku shouldn't do. Izuku explained that it would be his first time and apologised in advanced about his poor performance or incase it's painful

Katsuki laughed saying he probably won't notice anything
10
Since it's his first time too

Izuku was stunned hearing that. Tears formed in his eyes. he groveled on the ground and apologised that katsuki's first time had to be with Izuku and not with someone katsuki actually loved. Izuku apologized that they had to be mated even
11
Though Izuku tried everything he could to stop the marking incase katsuki ever wants to get out of here but he was so damn powerless

Katsuki had stayed frozen on the bed, listening to this rambling and realising that he was not the only victim here. Maybe Izuku too wanted to
12
Fall in love like a Normal person, court someone and mate with them- not stay stuck with a omega who clearly doesn't want to be here

Katsuki had hurriedly drank the herbal mixture that would induce his heat and greeted Izuku in bed
13
3 days later when katsuki woke up coherent from his heat, his scent gland was throbbing due to a open bite wound along with stomach ache from his pregnancy

His alpha was even more restless now that his "mate" was "pregnant" with his child but this time, katsuki didn't turn down
14
Requests Izuku made. Katsuki wanted to be better omega to Izuku, so he went together in the walks, sat down on the dinner table and actually receive the orange tulips Izuku offered

When katsuki was 5 months pregnant, he received countless gifts from the people of his tribe
15
Congratulating him for the pregnancy. there was a necklace, made by kirishima and drenched in his scent. Katsuki sniffed the comforting scent, his fingers hovering over the tooth or stones of the necklace, that had a clear message only understood by katsuki
16
Kirishima had planned a attack and snatch katsuki back again

Katsuki pressed the the necklace against his nose, engulfing every last bit of scent while his hand rested on his belly.

Just to be sure nobody can see that necklace, he tossed it on fire
17
Katsuki gave birth to a baby boy. He held that tiny soft baby on his arms. He was in awe. The baby was so precious, he felt like he had found a treasure. He wants to protect his treasure, keep him safe and healthy

Katsuki had never loved anything or anyone like this before
18
"thank you"Izuku was beside the entire time,patiently waiting

Katsuki allowed him to hold the baby. And laughed when the great Izuku midoriya cried while holding a tiny human

For the first time,the alpha asked if he could scent katsuki, the child and Katsuki's nest. He allowed
19
_
Katsuki woke up at the sudden presence he felt in his room. A silhouette,a familiar smell

Kirishima

Part of katsuki wanted to run up and hug kirishima. Katsuki was so sure he had let go of his past,had moved on but now that kirishima was standing right Infront of him, katsuki
20
Remembered how his heart still longed for him, how he loved him like no other

Kirishima apologied that it took him so long. He said he had been trying all these times but the castle is so hard to break though. Kirishima could only break though because of help from someone
21
Inside the castle. But it doesn't matter. He is here now and nothing stands between them

Katsuki breathe in the scent. He had already given the kingdom a heir, if he fakes his death now, nobody will look for him, yes. His child will be taken care off too, Izuku had promised that
22
Oh.. had Izuku been the one to help? So katsuki could escape if he wanted to. Is this why he wanted katsuki to scent the blanket, incase he leaves tonight

Suddenly the hallway got loud, sounds of footprints coming closer. They must have found out that there's a intruder
23
"let's go" kirishima hurriedly grabbed katsuki's hand but katsuki snatched his hands away, with a violent "let go" scream that achoed the room that even shocked the blond

Katsuki thought he still loved kirishima, he was sure he still had feelings for him

Then why the reaction
24
Why did it felt like kirishima was here to take katsuki away, from his own family

Katsuki knows Izuku would find a better omega, katsuki knows his child will be taken care of then why did the thought of leaving made him sick? Why did the image of some omega touching HIS son made
25
Him want to throw up

What had changed? But katsuki still loved kirishima?

Katsuki's scream had woken the baby up. The little baby immediately started crying and throwing his arms around

Katsuki quickly picked up the baby, turning his back towards kirishima
26
"I've moved on" katsuki rocked his child " you should too"

Did he really?

Kirishima was right here, along with his old friends, his old life. He could just go back and pretend nothing of this ever happened
27
But what's keeping him here?

Was it Izuku? Or his love for his baby and his future? Is katsuki choosing to be a father and a mate than a lover.

Katsuki looked back at kirishima.He looked broken, shattered " go" he said in the softest voice he himself had ever heard
28
The doors swung opened, kirishima jumped out of the door and katsuki stayed still on his position

___
29
Izuku entered the room with heavy footsteps,steps not matching a guy who's mate was stolen from him

He sat down at the empty bed, picking his baby boy up "guess it's only me and you now" he booped his little nose " I promise I'll be the best papa out there"
30
"You sure you could beat me?"

Izuku turned quick towards the voice. Katsuki was here? "Kacchan" he gasped

Katsuki was sitting legs crossed at the far corner of room, Izuku didn't see him cause he didn't expect to see anyone
31
"you're still here" he got up

Katsuki looked away, feeling shameful for infidelity he almost commited

Izuku ran towards him and wrapped his arms around katsuki, engulfing him in tight hug "you're still here " he cried " I'm so happy"
32
Tears formed on the corner of his eyes as a blissful content smile spread over his beautiful face

Katsuki didn't expect such reaction. Regardless he tapped Izuku on the shoulder

"I'm choosing my family"
33
" thank you" Izuku sniffled " thank you so much"

Katsuki stayed frozen on place, suddenly feeling guilty that he almost left Izuku alone, in this empty chambers with their tiny little baby

"I love you" Izuku planted a kiss on top of katsuki's head
"I love you so much kacchan "
34
Katsuki's eye blew wide open, is this why he stayed?

" If you love me so much, stop trying to get rid of me " katsuki looked away " show me you love me instead"

Maybe one day, katsuki will love him but just as much
35
Izuku gentle grabbed katsuki's chin and plant a soft kiss on those soft lips

Heat rose on katsuki's face, making it cherry red

Did Izuku just kissed him?

Izuku pulled Katsuki back on the hug and the blond hid his face on Izuku's chest
36
" of course" Izuku gulped down, calming himself back " I promise you, you'll never regret this day kacchan"

He sniffed "I promise you kacchan, I'll love you like no other"

Katsuki wrapped his one arm around izuku's waist and other around the fussy baby on Izuku's arms
37
"I'll hold onto that promise" katsuki knows Izuku will succeed, after all his heart has already been opened towards Izuku

~~~
The end
38
Note: katsuki had originally stayed because of the baby
He didn't wanted to stay away from his own child or let someone else raise him
Katsuki knew he could never go back to his old life the moment he held the baby for first time
