Long As We're Together

Summary:

Izuku and Katsuki finally decide to have a kid but you can nver be too careful so the couple decides to have a check-up first to see if everything is ok.

Good thing they do.

Notes:

After a long while, I'm actually quite satisfied with this one.

I might make a series of this but not sure yet.

Please enjoy.

(See the end of the work for more notes.)

Work Text:

“Come on, Deku! We’ll be late! Get your lazy ass up already, breakfast is getting cold.”

Izuku groaned as he hugged his pillow tighter. Katsuki crossed her arms and tapped her foot to the ground three times before she pealed the sheets off of her husband and basically hauled him up on her shoulder.

“Wha- Kacchaaan! You’ll drop me! Get me dooown!”

“I’m a pro hero, you jerk, I carried twice as heavy things if not much! Keep forgetting who you’re married to and I’ll carry you around like a prize dog from now on.”

Izuku whined as he tapped on her back to get her to put him down.

“’m sooorryyyy, Kacchaaan! Please put me down, your shoulder will hurt. I promise I’m awake now.”

Katsuki sighed and put him down begrudgingly. Crossing her arms again as she huffed.

“You losing weight on me, nerd? Surely you felt heavier before.”

Izuku avoided her eyes and mumbled unintelligently.

“Yeah, louder Deku, let the class hear you.”

“I-It’s nothing! I’m just… worried… a little.”

Katsuki frowned.

“’bout what, dumbass? You better know I’ll ace all the tests today, nothing to worry about’em.”

Izuku smiled but it didn’t reach his eyes. Katsuki shook her head and stepped into his space, holding his cheeks and locking eyes with her husband.

“There will be nothing wrong. We’re the perfect couple, remember? The fucking Wonder Duo!”

Katsuki put a quick peck on his lips and smiled warmly. She was worried over her head and had been this whole week since they’ve arranged the appointment. She was just better at hiding her emotions and she knew Izuku was super sensitive especially when it was about Katsuki. However many times the ash-blonde warned him didn’t matter but it was endearing so she just let him.

Only then Izuku smiled warmly and kissed her again with more passion and poured his love into it. Hands found their designated places on Katsuki’s small waist and her arms tangled around his neck. They broke off and Izuku spoke with a small whisper.

“Yeah, we are. I love you so much, Kacchan.”

“Mmh, me too I guess, dumb Deku.”

The strong façade fell when she couldn’t stop her hands from shaking anymore in the waiting room. It was hard as it is to manage small explosions from getting out but the shaking only got it worse. Just as another little crackle erupted with tiny sparkles, Izuku intertwined their hands. Katsuki turned to tell him off, that it was dangerous when Izuku squeezed tighter.

“It’s ok, you won’t hurt me. Just let it out for a few seconds. Or your palms will ache all evening.”

Izuku’s hands gotten firmer and tougher as years went by from the impact of his quirk and the way he uses it. Not being the soft piece of skin anymore, he would help Katsuki out in situations where she was having hard time controlling them from time to time. She’d refuse to do so and try to manage herself better most of the time but not today. She needed the firm and grounding presence of Izuku. So she let out the tiny explosions, kept them as less violent as possible.

“… I’ll put ointment on them when we’re home. Promise.”

Izuku smiled and kissed her cheek. His loving gazes were too much for Katsuki to handle.

“I don’t care if I end up in a hospital bed as long as it’s you, Kacchan.”

Katsuki felt hot all over her face and neck, knowing full well she was glowing red.

“S-Stop it, dumbass. That’s cheesy as fuck.”

“Mmh, nah. Not as cheesy- Agh!”

Katsuki elbowed him on the stomach, hiding her face as she slipped under his arm.

“I hate you.”

Izuku smiled, when he heard her chuckle right after.

“Yeah, love you too.”

“Uhm… Katsuki Midoriya-Bakugou?”

The couple jumped to their feet from where they were snuggling, as family friendly as possible.

“Yeah, that’s us.”

“Dr. Himawari will see you now. Please come in.”

Katsuki looked at Izuku, stress written all over her face. Izuku knew she had been stressed out the whole week. Her poker face could’ve fooled anyone but not Izuku. Him not pointing it out didn’t mean he tried to elongate their cuddle sessions, made love instead of rough sex they both tended to do more likely, took her out to just walk around when they were both done with work. He’d worship her and praise anything about her whenever he could anyway but this week, he showered Katsuki with compliments and love, because they both needed it.

“Whatever the results are, I love you more than anything and I will always be there for you. Don’t forget it, ok?”

Katsuki looked deeply in his eyes, searching for a lie or some kind of doubt. She could barely believe their togetherness as it was but here she was looking into the man she loved straight in the eyes, finding nothing but rivers of love and affection filled with adoration. Like she hung the goddamn stars for him.

She knew there were risks, even without the doctor telling her about it. She prepared herself for the worst if it came to that but… everything was just so perfect that she didn’t want to think of bad.

She smiled back knowing she wasn’t fooling her husband but still.

“I love you, too. Let’s hear what they have to say.”

“Hi, Katsuki-san! Can I call you Katsuki?”

“Sure, whatever. So?”

The petite woman gave a knowing smile and turned to the results. The doctor’s face paled a little as she looked through the result papers, although it was such a little change that you wouldn’t notice if you didn’t look hard enough.

She eyed the diagrams and circled some parts on the tabloids. After five or so minutes which felt like five hours to the couple, the doctor clicked her pen a few times as if she was trying to gather her words.

Then Dr. Himawari cleared her throat and let the pen down, looking at the couple.

“So, you have been here to check if having children is ok and if anything was wrong, am I correct?”

Katsuki was unable to speak; her whole body was trembling after she saw the doctor’s slight reaction. Izuku was the one who spoke after he held his wife’s hands inside his two palms. Katsuki didn’t retract them if not shuffled closer to Izuku.

“Yes, ma’am.”

 

She nodded slowly as she fixed her glasses and intertwined her fingers on the table.

“I looked through the results and I can confidently say that Katsuki-san has a perfect health. Nothing unusual or worrying in her tests.”

Then she stopped again. She was avoiding the very thing they were here for.

Katsuki cut her silence.

“…But?”

Izuku looked at his wife to see tears already prickling little by little. She knew there was a “but” in that sentence the moment Dr. Himawari fixed her stance.

The woman cleared her throat and smiled before speaking.

“But, we have also analyzed the nature of your quirk since it’s based off of chemical substances. It seems your mother had a chemical based quirk as well-”

“She can secrete glycerin.”

“Oh, yes. Glycerin is but a saccharide so it didn’t seem to affect her pregnancy, even though I must admit the risk was there with your father having a nitrogen based quirk if I’m reading correct from the information before me.”

“Yes, my mom had a preterm risk but the doctors told her that I probably had a quirk adapted to the substances by then. She said they were lucky because they didn’t think about it beforehand and didn’t try for another kid… y’know, because of the risk.”

“That’s why we wanted to make sure it’s safe before… well…”

“I understand, Midoriya-san, believe me I do. And it turns out you did the right choice, I’m afraid.”

Here it was. The cat was out at last.

Katsuki froze up. Her trembling hands inside Izuku’s stilled as the whole world did so for her.

She barely stopped herself from breaking as she listened what the doctor has to say.

The doctor had a lot to say.

“Katsuki-san’s quirk contains substances of explosives to run through her system, igniting on command. As much as it might have been the case with your father’s if enough pressure was provided, your quirk is more responsive and easier to ignite. It also is an abnormal amount of nitroglycerin for any normal human being to be subjected of and the only reason you’re not being poisoned by your quirk is the adaptation your body went through. My best guess is since both your parents had chemical based quirks, you genetically had the required defense mechanism by birth.”

“The level of adrenaline you have is also an outcome of your quirk, as the previous health check-ups of yours had reported so. You always feeling on your toes isn’t exactly your personality but your quirk slightly corrupting your body. Like I said though, you have been born with the required genes to fight them off.”

Izuku could feel the ragged breathes Katsuki was taking. She was a smart woman, of course she had a good idea what was to come. So did Izuku. He still put his arm around her shoulder, trying to give her some sort of comfort. He tried to let her now that he was still here no matter what the doctor was about to say.

Katsuki didn’t react; not appreciative, not refusing the touch. She just tried to breathe, tried not to break. Not here.

The doctor saw the action but decided not to comment on it. Her patient probably needed that right now.

“Now about Midoriya-san’s quirk… He is a late bloomer with a strength enhancement quirk along with six other branches to it, I believe? I’m afraid none of them happens to be related to any kind of chemicals…”

Katsuki was having more difficulties in breathing, her eyes blurring.

“… Also his late blooming might be a clue for a quirkless next generation, however much of a strong quirk he possesses…”

She gripped Izuku’s hands, her shaking coming back full force.

“… Now, I won’t say it is impossible but there is a high chance your child could be quirkless, have a non-chemical quirk or maybe even a mutation on the quirk side since it happens more often these days…”

This was going exactly to the worst case scenario Katsuki had in her mind.

“… It is my job to warn you from taking wrong actions so I will be direct with you…”

Katsuki held her breath, ears ringing. Izuku was constantly hushing her and rubbing soothing circles on her back. Even that wasn’t helping, as it generally did.

“… You have a high risk of miscarriage. Even if you managed to go through that, you might have a preterm labor. That is if the child isn’t poisoned by the substances of your quirk should they have nothing to fight back with…”

Katsuki gasped at that and buried her face on Izuku’s chest. Izuku didn’t waste any time holding her.

“… The only possibility of a healthy baby would be if they had your side of genes and defense mechanism but I’m afraid we can’t determine or make sure of it. We can only see to it after you got pregnant and are in seven to eight weeks, the earliest. Even then, if it’s risky then you would have to-”

“Thank you, doctor, that would be enough. We’ll be leaving if there’s nothing else.”

Dr. Himawari gave an apologetic look at the state of Katsuki and shook her head. Sure she said she’d be thorough but the truth hurt nevertheless. Katsuki was jumping with suppressed hiccups now and Izuku just had to cut her. He couldn’t take it anymore, neither his lover suffering nor the distasteful news.

“Come on, Kacchan. Let’s go home.”

“Kacchan, it’s ok-”

“Shut up.”

“I-I mean it-”

“Izuku, shut the hell up!”

Izuku closed his mouth so fast his teeth clicked. But what else could he do with his wife looking at him with hurtful eyes full of tears, a sour expression on her face? It wasn’t like Katsuki to show his weaknesses alright but it was even more unlikely to cry in a public place, like in the middle of the hospital corridors. She just turned his face away from him, hiding her face behind her bangs.

“I wanna go home. Now.”

Izuku sighed and put his arm around his lover, taking her in a half hug. He put a small kiss to her temple when she sobbed but cut herself off before a second one.

“P-Please…”

“Whatever you want, baby. I’m here.”

Then Izuku filled a couple of papers for their leave. Katsuki didn’t speak a word; her tears only escaping a couple of times as she tried so hard to put up a strong fort. Their walk back to the car was also a silent one, Katsuki suddenly very cold and distanced. She didn’t answer however much Izuku asked if she was ok.

That was a given, since she wasn’t ok at all.

Izuku just sighed sadly as both got into the car and drove in another endless silence.

Katsuki hadn’t left the bedroom since they came back from the hospital. She turned off her phone almost immediately. Some of her friends and her parents knew about the appointment so she was sure she’d get a call sooner or later. She didn’t want to speak to anyone.

Talking about it would only make it more… real.

Izuku came knocking on the door a couple of times, being kind enough to not barge in even though she didn’t lock the door and he had easy access. He constantly asked if she was ok, if he could come in.

Katsuki kept quiet. Well, however quiet sobs and sniffs could be at least.

At the beginning of their marriage, they didn’t want kids. It was dangerous for such high ranked heroes to raise a child. Although Izuku was very fond of the idea, he would hint it every now and then between love makings and just daily life, joking about it to test the waters.

Katsuki didn’t want kids, not really. Number one reason was obviously the time she’d have to spend being pregnant and the first few months at least to tend to her kid because like hell would she trust anyone else to take care of them right after she popped them out. The amount of absence from work made her distance herself from the idea. Not to mention how her body would somehow suffer for at least a couple of years for her to go back to how it was before. That was just a shit ton of time lost and only for a life to brought in this world full of villains and danger.

Although after a while, her selective sight seemed to focus more on the families she evacuated or rescued. She saw how the children hugged their moms tightly because they were afraid to lose their mother as the father would come and comfort both the kid and his wife. It had happen more than a few times and the feeling just grew on her. It didn’t help her how close they lived to a playground and the route back home from work was that way. The bright smiles of even brighter futured children lit a fire in her that she didn’t realize she built up until then.

She wanted to show the world how the Wonder Duo would have the wonderful child everyone would envy of.

Izuku cried for days out of sheer happiness when Katsuki told him about it. He didn’t believe her at first and pouted until Katsuki countered his pout with her own, pretending to be broken by her husband accusing her of being a liar. Then Izuku quite literally jumped at her for a bone crushing hug. Well, bone crushing for anyone else, Katsuki was fucking tough so she took it like a champ, thank you very much.

She knew about the little inconvenience her mom experienced when she was pregnant with her. She used to talk about it whenever they looked through her infant photos, making Katsuki groan and roll her eyes saying she’s just making a big fuss about it.

She still talked to Izuku about it and they agreed for a check-up to make sure. However much Katsuki thought her mom was just exaggerating things back then, the ash-blonde herself couldn’t help count days and think of everything and anything that could happen. Izuku was helping through it as best as he can, that she could tell about the way he treated her like she was made of glass and could be broken any minute if Izuku so much so frowned at her.

She didn’t mind for the time being, she felt fragile herself about this as well.

Hearing it was… worse than knowing, feeling it. Having an expertise pointing out and hitting you with the facts you conspired about for a week was apparently harder than she anticipated. If Izuku didn’t interrupt the woman when he did, Katsuki would probably have the break down she tried to swallow the whole appointment.

She knew, of course she knew, that there were major risks and multiple possibilities. There was also the part where Izuku was originally quirkless that Dr. Glasses didn’t know about. Izuku’s side didn’t have any chemical quirks either, apart from Izuku. If they somehow, miraculously had their child on their arms… they could be born sick. Having your own child suffering their entire lives because of her selfish desires was unfair at best.

And the thought of having to have an… abortion just simply devastated her. Taking away a life that has yet to sprint and losing the child she didn’t even have yet…

However you looked at it, it was a fairly low chance that their little baby inherited Katsuki’s genes with no non-defensive ones from Izuku whatsoever and was born perfectly healthy. The only option she’d have a non-risky pregnancy would be with a partner with a similarly dangerous chemical quirk owner but that idea was off sided before it even bloomed. There would only be Izuku and Izuku alone, no one else.

She was upset to hear the news, if you put it very very simply but what she was even madder and more disappointed about was the hope she gave to her lover. The unintentional promise she presented but then took away abruptly from his hands. The way Izuku tried to hide the sorrow that settled deep inside his eyes and heart. He was trying to look strong and keep up his high spirits for the sake of Katsuki but knowing Izuku for since she knew herself, she didn’t even have to try and look past the walls Izuku put up.

So Katsuki wasn’t… avoiding Izuku, she simply didn’t have the courage to face him after this.

Izuku let Katsuki have a little more time to collect herself, didn’t bother her until dinner. He was dying inside knowing the news broke Katsuki apart and she was crying inside their bedroom. She was crying because of Izuku’s weak genes. She was falling apart because everything they had planned just vanished into thin air before even forming a shape.

Izuku was used to it. He was used to having another weakness thrown at his face and the life itself laughing its ass of at him somehow, anyhow. But now that they were together with Katsuki, he was dragging her along to this cheap drama.

She had such high hopes of being a family with a child in the frame. She was so happy about being the best mother ever and “showing every extra out there how to raise a brat” and all. She looked excited to give Izuku a chance to be a great father, too.

It was all Izuku’s bad luck she was dragged into.

Maybe if she was together with someone else, with someone she can have a happy family together…

Izuku didn’t want to give up on the love of his life ever but… if he knew that it would make her feel better now, he wouldn’t waste any time filling up the divorce papers.

Just so he can stop the muffled sobs and whimpers he heard every ten minutes as he checked up on her.

He didn’t interrupt her, didn’t want to intrude. He only wanted her to be happy and Izuku didn’t think looking at the very reason she couldn’t have a child was a good idea. He offered her nonetheless but didn’t get an answer, as he couldn’t have been able to the whole day after the appointment. But she must at least have been dehydrated so Izuku decided to take a chance at going in. He has been busy making dinner so he didn’t check up on her for the last hour.

Izuku got a glass of water with him as he walked towards the bedroom. He knocked on the door softly.

“Hey, Kacchan. I’m coming in, ok?”

Then he opened the door slowly as to not startle his love… only to find her hugging Izuku’s pillow and sleeping soundly. Her eyes red and puffy, some salt dried on her cheeks and lips red, swollen with her biting into them to muffle her noises.

The scene only broke Izuku’s heart more; his own pair of eyes filling with tears already.

He sniffed once and approached his beautiful wife, slowly sinking next to her and brushing some stray hair behind her ear. He then caressed her cheeks clean of the remnant tears, put a feather light kiss on it. That finally made her space her ruby eyes and look up at the green orbs.

“Slept well, baby?”

She blinked up a couple of more times and avoided his eyes with a blush.

“How l’ng?”

“About half an hour I guess. Here, drink this.”

He helped Katsuki on her seat and handed her the glass of room temperature water. She drank it in silence and frowned as the beginning of a headache showed itself slowly. She handed the glass back to Izuku and rubbed her temples.

“C’mere, I’ll message your head. You can drink some chamomile tea after dinner, that should help.”

Katsuki wordlessly lowered her hands down and let Izuku do his magic. The dinner would be ready to be served in about ten minutes so they had enough time yet.

“Are you… not gonna say anything?”

Izuku hummed, not wanting to acknowledge the elephant in the room.

“Say what?”

“Izuku.”

Katsuki held his hands rubbing her temples and turned to face him. Her eyes were already filled with tears.

“Why aren’t you breaking down?! Why aren’t you throwing a tantrum?! Why aren’t you mad, Izuku?! Or was I the only one that was enthusiastic in the first place?! O-Or have you lost all hope on m-me?!”

“Stop!”

Katsuki stilled as Izuku flared with green lightning for a mere second and calmed down just as quickly. He looked regretful already.

“S-Sorry, I didn’t mean to…”

“No, it’s fucking fine…”

Izuku sighed, trying to get his adrenaline back down. He closed his eyes and took deep breaths before he opened them and retracted his hands from the ash-blonde’s to cup her face.

“I would never give up on you, Kacchan, not even over my dead body. I just… wanted to give you some time to take in the news and since this is all because of me I-I didn’t think you would wanna see me is all.”

“What the hell are you talking about? What do you mean it’s all because of you?”

It was Izuku’s time to face away from his wife.

“You know, it’s because of my bad luck and weak genes- If you had a better husband- Maybe with a chemical quirked one too- And now I dragged you into my mess of unfortunates that’s my life-”

Katsuki slapped Izuku across the face and before he could even have time to recover or recognize it she was on his lips, giving him one of the most passionate kisses the explosive blond has ever given.

When they parted, Katsuki’s face was red although Izuku wasn’t sure if it’s because of anger or arousal. The frown between her brows was the clue he needed.

“I can’t believe how much of a fucking dumbass you can be sometimes!”

“Ouch?”

Katsuki shook her head and guided Izuku’s hands around her as she snuggled into Izuku’s chest.

“Idiot. It’s because of the toxins in my quirk that we… It’s no guarantee that, according to your oh so great deductions, any other partner would have the correct genes to prevent shit from going south. Not to mention I’d rather die infertile than to have a brat with anyone else other than you! Stupid, jerk, idiot, bastard… I can never love anyone else enough to do that…”

She was sniffing again. Katsuki didn’t remember ever crying this much, heck, she cried more than she cried her whole life, probably. Izuku brought his nose and buried it in soft blonde locks as he inhaled deeply of her strawberry shampoo and put a kiss on her crown.

“Are you sure you’re ok with… this?”

Katsuki didn’t answer right away. She was silent for a while as Izuku wondered if he asked the question a little too soon but then Katsuki sank deeper in his chest as if to disappear inside her husband’s pecks.

“It’s not that we can n-never have children o-or try. Maybe luck will be on our side and we’ll have a beautiful kid at first try. Of course I want to have a child, I don’t fucking back away from anything but I-I don’t know, Deku…”

Katsuki sobbed and held onto Izuku’s shirt.

“… I don’t know how I’d handle if we lost them, whether inside me or after they’re born. I don’t know how to soothe my consciousness if they were born s-sick and they suffered constantly just be-because we wanted a brat to raise…”

Katsuki sobbed again and clung on Izuku, not only physically but also mentally. Whatever left those sacred lips would either chase her pain away or drown her further.

So she waited. Izuku rubbed circles on her back but didn’t speak until Katsuki could breathe normally again and then pulled her away from his chest to look into crimson red eyes with determined emeralds.

“This isn’t the end of it, Katsuki. We live in a quirk society with dozens of doctors and right as much quirks to help people. I highly doubt we are the first and the last couple to have such problems. We’ll find another way. But as long as we set our minds into this, there’s nothing that can stop us. I promise I’ll find a way, ok? So please, don’t give up on this, on us…”

Katsuki weighed his words for a while. He was right, there were people with even more confusing and sophisticated quirks. Dangerous quirks that rivaled Katsuki’s explosions must have had kids, right? As she searched through the few possible solutions that popped up in her mind at the thought, she realized she was ok with most of them.

She nodded. Then nodded again, this time more to herself than Izuku.

“No surrogate mothers.”

Izuku chuckled and hugged her to his chest.

“No surrogate mothers, copied.”

“Good. Or I’ll have to chop off your dick.”

“K-Kacchan it doesn’t work-”

“Oh I fucking know how it works, damn it! Your jizz mine and mine only, don’t even think about it!”

Izuku let out a genuine laugh at that and Katsuki couldn’t help giggle at her husband.

“You’re such a jerk, how’d I end up marrying you?”

Izuku hummed as if thinking for a few seconds.

“Hmm, let me think. I’m smart so I tricked you, also hot as hell fire so I burned your eyes and you just took me in blindly, don’t forget my sharp tongue that cut through you ears right to your brain and boom, you’re stuck with the nerd- Hey, don’t laugh at this, I’m making theories!”

Katsuki was rolling on her side, holding her stomach as tears of joy spilled from the corner of her eyes. Izuku wanted to carve the moment to his brain forever to only relive this moment for the rest of his mortal life.

He smiled down at her and kissed her lips, catching Katsuki off guard for a second there.

“I am so in love with you. Please only cry if you’re happy or overjoyed from now on ok? I’d rather have a thousand daggers in my heart than to have to listen to your whimpers ever again.”

Katsuki’s face fell but she blushed hard before grinning playfully.

“You’re impossible, has anyone ever told you that? Cheesier than my romantic novels, and believe me that’s saying something.”

“Yeah, my wife says that a lot actually, you should definitely meet her sometimes. Besides…”

He leaned in kissing her lips with each emphasis.

“Two. Can. Play. This. Game.”

Katsuki chuckled and tried to catch his lips every time he parted.

“Oh? I didn’t know you were married. Were you fooling around with me this whole time, Mr. Hero?”

Izuku smirked and ran his hand through his hair.

“Oh I wasn’t fooling with you, you just fell for me naturally and I didn’t break the spell. My wife would hang me to the ceiling by my prick if I ever cheated on her.”

Katsuki laughed and shoved him away, making to get up.

“Damn right I would, if I didn’t kill you right on the-”

Katsuki stopped and sniffed the air, and then sniffed again with her face scrunched up.

“Deku, is something… burning?”

Izuku frowned before his eyes opened wide as saucers and he jumped on his feet, already running out of the room.

“Oh my God, the dinner! My curry!”

Katsuki just shook her head with a sigh and a small smile, watched as Izuku regretfully watched the blackened poor substance before she kissed his cheek and called for their favorite take-out restaurant. They ate in a better mood than before and that was all they asked for, for the time being.

As long as they were together, they would be fine.
