Chapter Text
Half a year ago Katsuki would give zero fuck about everything besides working himself to death. It only took him one fucking night and he got knocked up. It was his fucking first time to boot, how ironic his life would be. As a Dominant Omega he never cared about getting Alpha's knot like any other typical omega yet he bore a handsome stranger prominent and healthy 8 weeks fetus as his obgyn doc said (he even received an ultrasound copy that was supposed to be his baby, which didn't look one bit). The logical thing he was supposed to do is terminate before it was too big, but ever since he'd met that alpha his omega instincts were kicking him hard. Call it whatever but Katsuki would never do any harm to his child. It wasn't even a month ago he wanted to split open his head because an infant was crying for 10 minutes straight (he was waiting in line for a popular croffle shop-- it explained enough that he suddenly got a sweet tooth because of the pregnancy). Katsuki wasn't that stupid; he had constant bladder, nausea, fatigue, and then sudden switch of tongue and constipated randomly? Pregnancy 101 right there. He hadn't known he would conceive because the alpha didn't knot him, apparently as the doctor said if both alpha and omega were dominants sometimes a miracle happened, because dominants genes were uncommon; omega can only conceive when they're in heat, or when an alpha's knot in rut. Katsuki wasn't in heat at that time, he had his heat cycle under control he'd gone through one 2 week before that night. However he considered himself lucky that finally he found an alpha who can handle his pheromones. Out of hundreds thousands people he'd seen throughout his life this one fucking alhpa was the first one he can smell.
Katsuki had already finished his first prenatal visit. He had to fill the pregnancy registration so that he will receive his maternal and child health handbook (boshi techo). Fortunately for him the dumbass alpha gave his name and number that night, though Katsuki had never called. At least it made things easier for him to fill the paper. He would bring it to his grave that he kept the scribbled notes the alpha had left. It was cute.
Katsuki walked out of omega's clinic with a boshi techo and vitamins felt so damn heavy in his hand. At least he knew the baby and him were healthy. That was a plus.

Katsuki was 24, dominant omega, unmated and pregnant. The only thing that kept him positive was his financial stability, because he knew how hard it was having another life to support. He worked as a cook for nearly three years; it paid well and he only had to work 5 hours per day. He also had a part-time job as a bartender just because he hated being idle. He had to stop both for his health, which he will soon do; both his works put a lot of strain on his feet and lifestyle--he didn't want to harm his pup. Katsuki didn't like the idea of doing nothing for 7 months prior. Despite his financial stability he still loathed the idea of not working. Maybe he will start cooking class online or something. He was privileged, and he didn't like to make a big deal of his pregnancy like some naive virgin despite being one recently. He obviously can afford luxury, all he needed was emotional and mental support. He was doubtful anyone can go through pregnancy alone.
He got home and sat comfortably on his sofa. He took his phone out as he put on schedule for his next prenatal visit. He hadn't told a soul about his pregnancy. The troublesome part was his parents. Katsuki didn't want his parents to meddle in his life ever since he left hometown 3 years ago after he finished college and got a job in Tokyo. He was grateful for them giving him an apartment in Tokyo and still giving him a monthly allowance of about 200k yen; as he said he was privileged as fuck. They visited him regularly once a year on his birthday, always bringing many oimai candidates; to remind him another year he'd lost his fertile womb that he despised. His mother was an alpha who was very old fashioned, she wanted Katsuki to be a stay home wife material omega; if he ever told he was pregnant without a mate who knew what Mitsuki would do. He had to deal with pregnancy by himself until he birthed a beautiful pup then maybe telling his parents. He wanted to keep it a secret from his parents yet the timing was off; it was mid December and in 4 months he would be on his 3nd trimester, his baby bump would be fucking impossible to hide. His parents weren't good for his mental health. If he was looking for supportive shit, they would be the last one he'd go for. He was an adult and he had his own life. More importantly he didn't want their bad influence on parenting to corrupt himself more than he already did.
The luckiest asshole who'd be the first one to bear the news: Todoroki Shouto, the culprit.
'I'm 8 weeks pregnant. It's mine.' Katsuki texted.
Somehow in the deepest depths of his heart he hoped that asshole actually cared. Katsuki wanted to know the father of his child aside from what the internet had shown. The fact that he'd bear the richest bachelor in Japan was unexpected, it was beyond unthinkable. It was his first time meeting an alpha who was compatible with his strong dominant omega pheromones. He'd been living 24 years of life without a single alpha or even beta dare to approach him honestly. His pheromones were too strong for alphas; they'd ended up fainting or in some rare cases they'd gone feral, which was fine for Katsuki because he cannot smell any pheromones hence he wouldn't submit so he'd beat them up to pulp. Not until Todoroki Shouto, literally all his life he can only smell himself, he can't identify other people's secondary gender nor that he cared.
His phone rang not a minute passed by. Katsuki picked up as he took a deep breath.
"Katsuki?" a deep baritone voice that seemed awfully familiar made Katsuki flush. It made Katsuki remember that night he tried so hard to forget.
"What?" Stay calm.
"I am responsible for our child. Would you like to meet and talk about it?"
Katsuki would be lying if he said his heart didn't go haywire right now. Shit, "I can handle it myself. I am capable of raising my child alone. It was just a one night stand." Now that it was said out loud he seemed bitter, and somehow, lonely. He hated the word.
"I believe you are capable but I want to be included in our child's life. It might be just a one night stand for you. But not for me. I would rather meet you to talk about this, if you let me," the alpha sounded so sincere and apologetic and it made Katsuki's heart clench.
Katsuki blamed pregnancy hormones, he said, "Are you free now?"
"Yes."
"Come to my apartment. I'll send my location--3rd floor."
"I'll be there as soon as I can. See you."
Katsuki ended the call and shared the location.
'Will be there in 10.'
Katsuki looked around his apartment which was tidy as always. He sighed as he got up to his room. He changed his clothes to comfy shirts and sweatpants. He looked down on his stomach; it was rather bloated--his planes of abs had gone smoother. Then reality hit him. He was having another life growing inside of him. His stomach looked soft, and it felt good to touch it. Damn. He never cared about sentimental shit but now he wanted to capture every goddamn moment he had with his unborn pup. He took the first baby bump photo in front of the mirror from his side. He had to tell his so-called gank about it. Maybe a tease to the group chat.
He sent his picture to the group.
Kirishima: Bakubro wanna hit gym later?
Kaminari: UR GLOWING THO SPILL!!
Mina: preggo boy?
Kirishima: WHAT
Kaminari: HUH FR?????
Sero: mina r u ok wth
Katsuki: F
It was probably better if his nosy group friends knew about his pregnancy, they were gonna get batshit real quick as well as supportive, he knew they would. Katsuki snorted as he went back to the living room. Maybe he'll invite them later tonight after things sorted out with the asshole alpha. He still can clearly remember that unholy night was pretty messy, Katsuki might have blacked out once or twice because of his omega inside him unveiling for the first time. He didn't know he could be submissive, somehow the concept was abnormal to him. Long story short: Katsuki was on his way home after his bartending job, it was almost midnight and suddenly he smelled someone's pheromones for the first time; he went all weak on his knees and unfortunately his omega-self that he wasn't aware ever existed suddenly bursting out. The rest was history, an unforgettable one though. No toys could satisfy him like a real alpha's cock did. Honestly after that one time he'd said goodbye to his toys. Katsuki was ruined, sexually. He never knew fucking an alpha's cock would feel that good. No wonder omegas were always suckers for alphas' knots because look how only one time he'd got a taste of a cock would make him like this. It was bizarre. Now wasn't the time to think about how magnificent that alpha's cock was. At least he knew this alpha didn't seem like those typical alpha assholes. It was too early to judge but Katsuki had a gut feeling.
Katsuki got tensed up as he smelled the familiar scents waft into his living room, it was really overwhelming yet alluring pheromones that made him go weak. Fuck. He felt like that night replying to himself. Katsuki strode to the door and opened it with an angry snarl, "control your goddamn pheromones, shitty al-ocuh!"
Katsuki was greeted by a knuckle to his forehead and a bouquet of red roses centimetres apart to his face, he jerked back, startled.
"I'm so sorry. I was about to knock, are you alright?" The alpha took a step back.
Katsuki caught his breath when they met gaze. His life would be damned, he knew this alpha was god-tier attractive but it was that night induced with lust and some pictures online, and somehow people would always look much better at night and the photos but not for this alpha. Katsuki had to squint his eyes because the sun behind this alpha was making it look like a halo. Look at those beautiful mismatched eyes and hair, strong jawline, broad shoulders, and this hot fucker was taller than he'd remembered. Katsuki wanted to moan just remembering what was beneath the alpha's designer suits. He turned his back once he felt like his face heated up. "Come on in, switch your pheromones off, are you in rut or something?"
"It's your half marking on me that made my pheromones uncontrollable," the asshole alpha said as he entered his home and closed the door behind.
Katsuki snorted in disbelief, "Omega can mark alpha nowadays, huh?" Katsuki gestured to his sofa. "Explain yourself."
The alpha looked confused at Katsuki; his right hand holding the bouquet but then he unbuttoned his suit then took a seat in front of him, now holding the bouquet with both his hands. He was looking unsure when he said, "um…, I'm sorry about the other night. It was my very first rut triggered by your pheromones. It was unfair for you, and I left early because I thought if I were to spend the rest of my rut with you I'd end up mating you. Apparently you are one step ahead? You already marked me, I wouldn't be able to control my pheromones until I mark you back, I think?"
"What the actual fuck?" before Katsuki's brain can function properly the fucker continued.
"It really was my first time having my rut. I can't handle omega pheromones, not until yours. But thanks to your marking my pheromones changed as well, no omega tried to pursue me anymore. So… My doctor said it was unheard of for omega to mark their alpha. Ours was the first case he ever treated," he then put the bouquet on his lap as he started to unbutton his collar button then another one down.
"Wait a damn minute! What the fuck are you doing?"
The alpha showed a bite mark on the base of his neck, it didn't look gruesome, somehow normal, not even red; it was just teeth marks honestly. He did remember biting the alpha but he didn't know that was marking, what the fuck.
"This was your mark on me, and I'm grateful for that despite me having to go through a rut for a week. Marking is different from mating as I was informed. But still I didn't know how you'd get pregnant. You must be a dominant omega. I'm a dominant alpha as well. We might be a fated pair?" he tilted his head and looked so hopeful it made Katsuki want to scream adorable but shit was a lot to take. What the actual fuck happened. Fated pair was only urban legend bullshit yet right now it might be true for them, hopefully, Katsuki really fucking hated his hormones induced brain.
"I thought I was the one having a hard time here since I'm actually pregnant. What do you want from me anyway? I'm not expecting anything from you. Do you want to court me now just because I'm bearing your spawn?" he said sarcastically as he pointed his finger at the bouquet.
The alpha was buttoning his shirt back then looked down to the bouquet he brought, "do you want to go on a date with me? I'd like to know more about you," he said as he leaned over and gave the flower to Katsuki's face.
It was beautiful actually. Katsuki appreciated flowers, but this dumb alpha intention was crystal clear, to mate him without saying the word. Katsuki didn't mind getting to know this gorgeous alpha though, it was best for his baby if they were actually on good terms. But can the dumb alpha handle him? Katsuki took the bouquet and put it on the coffee table.
"How about you start introducing yourself first then I'll think about going on a date with you."
"I'm Todoroki Shouto, 25. I work in finance at Endeavor Corp. I don't know how to introduce myself. Sorry. Ask me anything I'll answer," he said sheepishly.
"No shit, I googled you and I got more than you even say here," Katsuki snorted as he crossed his arms.
"I hired a PI to find you, because you only told me your first name that night. I probably knew you more than you're comfortable with. But even if you hired a PI on me you wouldn't know anything more than google has. I was desperate to find you but I didn't reach out because I was already a stalker enough as my friends said. I'm thanking all the heavens above that you finally texted me today. I'm very sorry I went too far with PI," the dumb shit alpha bowed low and when he looked up his eyes looked so determined it made Katsuki heart flutter.
What was the point of hiring a PI if this dumbass would end up telling him right at the bat? It was amusing that a dominant alpha went so desperate as far as hiring a PI just for an omega that he'd fucked once. The typical alpha would abandon one after another omega or beta in every goddamn corner. It was insane on another level honestly, Katsuki was flattered rather than anything. He should be getting a red alarm but his guts told him otherwise.
"I bet that PI doesn't know about my fantastic toy collection. How much did you pay them anyway, you're so fucking dumb."
The alpha blushed and avoided their eye contact when he said, "10 million yen for every tiny detail of your life until now. The PI was your friend's mate: Shinsou Hitoshi. He was helpful. He told me a lot from your friend's perspective too. Shinsou said I was perfect for you and I should mate you no matter what. That's why I'm here." They met gaze again and this time the alpha looked really genuine and Katsuki wasn't even surprised when nausea hit him hard and he ran to the kitchen sink leaving the alpha behind.
He heaved the bile that surging to his throat and he vomited. He touched his aching stomach as he felt like his eyes tearing up, fuck. He retched again. Shit was painful in his throat and it was a lot more than he normally barf. A rather cool hand touched his nape and it started to massage his nape, it felt so damn blissful, he wouldn't mind getting used to this. He coughed some more and turned on the water to clean the mess on his sink. He gargled a bit more and then slowly caught his breath. His hand kept a comforting gesture on his stomach up and down then another bigger hand joined him, he unconsciously leaned back to the alpha behind him who was actually giving a really nice pheromone that he cannot name; it made him feel all better.
Maybe this dumbass alpha was all Katsuki needed? He cannot even say the alpha's name for goodness sake. The Alpha had come to him in all sincerity. He might as well try his best.
"Let's go out, Shouto. I'm hungry." Katsuki tilted his head up to see the alpha was looking down at him fondly, then a smile.
"Does that mean I get to court you?"
"I'd like to see you try, dumbass alpha," Katsuki turned his body so they're facing each other, he grabbed his alpha's hair to close the distance between their faces then he captured Shouto's lips.
Todoroki Shouto deserved the stinking breath that he still had left. The alpha was honestly the dumbest shit he'd ever known because he kissed Katsuki back, all tongue and shit, and it wasn't supposed to be hot because it was disgusting but fuck it was. Katsuki can easily blame it all on his pregnancy hormones anyway.
