Miyuki Kazuya learns from a young age that he’s a beta.
It’s not even a surprise to anyone because it’s already been a lot of decades since the Miyuki family have had an alpha in the family. According to his dad, it’s been his great-great-great-(Kazuya hasn’t really counted how far back it is but he knows it’s very far)-grandfather and that guy chose to marry a beta, starting the long line of betas in their family. It also doesn’t help that most of the Miyuki’s family line also married betas – it became a given that every kid who jumps out of two exasperated beta parents is a beta.
“I want to be a catcher!” exclaims Kazuya, an enthusiastic smile forming on his face when his coach asks for volunteers on the position.
His coach raises an eyebrow. “Are you sure you can handle that?”
“Yeah, you’re just a beta and you’re not even the strongest of them,” says one of the kids next to him tauntingly.
Kazuya frowns, bottom lip jutted and trembling. “But I want to be a catcher!”
The coach sighed. “If you can handle it, it’s fine, I guess.”
Kazuya looks at his peers defiantly, persistent on proving he can be one of the regulars on the team even though he’s not an alpha. He’s a small beta, sure, but he knows he can dedicate so much time to improve. They’ll definitely have to acknowledge him if he proves to be the best.
The fields are always occupied with Kazuya using all the free time he has to practice his batting and catching. Their pitcher is at least his age – he doesn’t want to deal with his older teammates – so he had even more fun improving his catching skill. It earns him a spot on the regulars, much to his older teammates’ chagrin. Kazuya should be happy, but that’s not the only thing he earned that day.
Kazuya has to spend most of his days dealing with bruises and wounds on his face and arms – he’s not as big as his alpha senpais so he has no way of retaliating, not that he’ll stoop that low anyway. It’s hard and painful, but he can deal with it.
If this is how a young beta is treated by older alphas, then so be it. Kazuya will still be the catcher he wishes to be no matter what.
Exactly three years later, he becomes the strongest catcher of his generation.
***
Kazuya starts loving to be a beta on his first year at Seidou High.
It’s not your usual daily news in the local television to see a beta becoming one of the best players on the baseball field – most of the time, alphas and a few omegas gain the most attention in sports. Kazuya hates the fact that people think betas suck. He’s a beta, thank you very much, but that didn’t stop him from being one of the best.
Kazuya doesn’t really care about the attention he gained from being one of the first betas to conquer a sport – he only cares about doing his best to win with his teammates and go to Koshien. Seidou High hasn’t gone to Koshien for years, and Kazuya wants to be there when they finally arrive on the Koshien stadium and reach the top.
“You’re an asshole,” grumbles Kuramochi as he refrains himself from punching Kazuya in the face.
Kazuya snickers and bares his teeth. “Thank you!”
“Not a compliment, you bastard!”
Kazuya likes Kuramochi a lot. He’s also a beta – and one of the strongest like him – which makes Kazuya respect him more than most of the players in their roster. But Kazuya knows his tongue is a dangerous weapon who can’t help but jab at even the players he respects the most. Tough love, but that’s what’s Kazuya is best at anyway.
Kazuya just wonders how long will it take them to go to Koshien.
***
Why is Kazuya a beta again?
Oh, right. He is born with it. But it kinda sucks because he just has to find out he’s got the hots for one of the loudest, most annoying, yet most gorgeous omegas he ever had the chance to meet. And he even smells really good too. Oh god, is this the time for him to act like an alpha now? He’s good at riling up people anyway – Kazuya is sure he can pass up for some strong, cool alpha. Heh, the omega is an idiot anyway.
Still, Kazuya kinda likes being a beta so he just decides to act like himself.
“Let’s slay this monster, partner,” he says at the omega, grinning at the way those golden eyes stared at him in awe. Kazuya may not be an alpha but sure as hell can be stronger than one. Maybe he can capitalize on that. But first, they have a monster to obliterate.
Kazuya places his mitt on the inside course and grins wildly. Warmth pools on his insides when he sees the omega grin back at him, his eyes lighting up brightly. Kazuya is not a romantic, but what the fuck?! Since when did he imagine a person surrounded by a golden light and sunshine? What the hell is wrong with his mind?! Kazuya squeezes his eyes shut for a few seconds to focus before moving his mitt towards the direction the pitch thrown at him broke.
The loud smack echoes across the fields.
“My, my, Azuma-senpai. That’s a strike.” Kazuya smirks teasingly. “You got a problem with your swing?”
Azuma scowls at him and points his bat. “I’m just trying to see if that omega can pitch. Tch.” He hoists his bat and takes up his usual batting stance. “I’m going to hit his pitch and blast it out of the fields so get ready!”
Kazuya snorts. “Alpha filth.”
It takes them eleven pitches to strike the arrogant alpha out, and Kazuya heart swells as he sees the omega roar triumphantly on the mound. Of course, part of the credit goes to him – the omega has potential but his pitches suck at control. In fact, Kazuya would’ve taken most of the credit if only the omega wasn’t so pretty – being attracted to omegas suck.
“What’s your name again?” asks Kazuya as he takes off his catcher’s gear.
The omega smiles brightly. “Sawamura Eijun.”
Kazuya tries not to sniff the sweet scent of summer on the omega. “I’m looking forward to seeing you next school year.”
Sawamura widens his eyes, cheeks flushed. “I can’t promise you that!”
Kazuya shrugs and makes a face when he turns his back away from the omega. So much for having crushes. He still wishes to see the omega again next year though.

“Miyuki Kazuya, catch for me!” yells Sawamura, making Kazuya flinch.
“You’re too loud,” complains Kazuya. “And nope, I can’t catch for you right now, Sawamura.”
Sawamura stops in front of him and raises him by the collar, making him grin wildly. “You tanuki bastard! Why are you so difficult?!”
Kazuya snickers. “You don’t need me to give you a big head, Sawamura.”
“Miyuki Ka – “ Sawamura suddenly loosens his hold on him, making Kazuya widen his eyes. “W-w-wait. I – “
“Oi, Sawamura. What’s happening to you?” Kazuya grits his teeth as he sees Sawamura suddenly fall on his knees. He catches him before his body fully hits the ground and slowly lowers him. “Are you pitching too much again?”
Sawamura shakes his head, body trembling and hand reaching out to cup Kazuya’s cheeks. Kazuya shivers at the touch, sending him into a frantic state of mind. “M-M-Miyuki Kazuya, why do you smell so good?”
Kazuya gapes and sputters. “What the hell are you saying?”
“I feel so hot.” Sawamura’s hand falls and he closes his eyes, eyebrows scrunched and lips frowning. “It’s really, really so hot.”
Kazuya doesn’t know what’s happening. He takes his mind back to their lessons about alphas, betas and omegas. Omegas usually smell an alpha’s scent that attracts them and that’s what makes them feel hot all over and… Oh shit. Kazuya slaps his hand on his forehead and curses. Of course, Sawamura is an omega. Omegas get heats. And wait, what the fuck? This is the first time he has ever seen Sawamura like this. Kazuya’s chest boils hot when he realizes that Sawamura must’ve smelled an alpha’s scent.
Wait. Kazuya shakes his head. This is not the time to be jealous. This is a really bad time. He has to get Sawamura to his room first. Kazuya lifts the pitcher’s body off, ignoring the way he’s feeling that strange sensation on his lower region – fuck, not this bloody ass boner he’s had a hard time getting out of again – and he forces himself to stop staggering as he walks back to the dorms. Kazuya tries to think of a way to tell the coach and Rei without having to leave Sawamura alone. But, wait. Oh fuck. Kazuya wrinkles his nose as he gets attacked by that sweet, oh so lovely scent again. When did he started to smell flowers and earth again? Kazuya tries to remove the thoughts swirling inside his head and kicks the door to Room 5 open.
“Miyuki, it hurts.” Kazuya’s chest clenches at the way he sees Sawamura wince while massaging his lower… Kazuya slaps himself before his thoughts could go wilder. “Help.”
Kazuya places Sawamura on his bed and tries to stop himself from panicking. "Wait, my phone, my phone.”
Kazuya growls when he fumbles with his phone, almost dropping it on the floor when he tries to text as fast as he can. He does his best to pinch his nose as he tries to type one-handedly, and to his displeasure, it takes him longer than usual to type a single text. Kazuya bites his bottom lip when he sees Sawamura whining on his bed while he keeps on calling out Kazuya’s name. No, Kazuya shakes his head, this is not the time to be distracted.
Kazuya answers the sudden incoming call with a sigh of relief. “Rei-chan?”
Rei’s voice exhales loudly. “Miyuki-kun, we have a problem. I’m at a teacher’s meeting with the coach at the moment. Can you tell me what’s going on right now?”
“He’s still writhing on the bed, Rei-chan.” Kazuya tightened the hold on his phone to prevent his hand from shaking. “He keeps saying my name – “
“Your voice sounds weird. Wait, he’s saying your name?” Rei’s voice sound amused, much to Kazuya’s chagrin. “Miyuki-kun, can you put Sawamura-kun on the phone for me?”
Kazuya nods then suddenly remembers he’s on the phone. “Wait, I’ll loudspeak this thing.” He nears himself to Sawamura’s bedside, still covering his nose to avoid inhaling the scent and ruin himself. “Sawamura, Rei-chan wants to talk to you.”
Sawamura whines. “Kazuya, just help me out here, please.”
Rei stifles a chuckle. “Sawamura-kun, can you hear me?”
Sawamura turns his head on the phone’s direction. “Takashima-san?”
“Do you agree to Miyuki-kun being your temporary heat partner for now? He’s a beta and your parents did tell me that if you accidentally get your first heat, make sure it’s a beta helping you and not an alpha.”
Now, wait a second. Kazuya tries to process what he just heard. He’s a beta. Sawamura is having his first heat. Rei is asking for Sawamura’s permission to let Kazuya help him because his parents agreed if it’s a beta. Kazuya helping Sawamura on his first heat. Kazuya with his crush on said crush’s first heat. What the fuck?!
Sawamura groans. “I’ve been trying to ask his help, Takashima-san. But Miyuki-senpai doesn’t want to help me.”
Kazuya stops himself from taunting the pitcher on his sudden display of respect towards him because this is not the most important thing right now. He thinks he’s getting hallucinations because there’s no way his crush just asked him of all people for help on his first heat. There’s just no way –
“Miyuki-kun?”
Kazuya stumbles out of his stupor. “W-w-what?”
Rei chuckles. “Can I trust you in helping Sawamura-kun right now? Please take this as part of your duties, alright? It’ll be more painful for him without your help.”
Kazuya gulps and looks at Sawamura one more time. “Alright. I’ll… I’ll do my best.”
“Good. Please don’t forget to lock the door.”
The call ends and Kazuya’s heart lurches when he sees Sawamura looking at him with those hungry eyes. God, what the hell has he gotten himself into? Trying to summon the last remnants of his courage, he nears himself to the bed and dips his body on top of Sawamura. The omega lets out a loud moan – Kazuya is about to lose his shit after hearing the sound. He cups Sawamura’s cheeks, rubbing them with his thumbs.
“What do you want me to do?” asks Kazuya, ignoring the erratic beats of his pulse and pretending that he’s totally not so nervous right now.
Sawamura wraps his arms around his neck and tugs him. “Kiss me.”
Kazuya feels the warm breath on his skin, and shit, he feels really turned on right now. He closes his eyes and leans in, brushing his lips on the pitcher’s soft ones. The touch feels so electric – Kazuya likes the way it feels way more than he imagined it inside his head. He presses his lips harder and coaxes Sawamura’s lips open with his tongue. Kazuya groans at the heat and taste surging inside him as he explores the pitcher’s mouth, feeling his face warm when he feels the omega trying to dominate him.
Kazuya pulls away and moves his lips on Sawamura’s neck, nipping and licking at the soft skin, making sure to avoid the omega’s scent gland – he may be crazy about this omega underneath him but he has enough common sense to not accidentally bond himself with him for life. (Kazuya regrets that he’s not listening that much to science class because he’s not sure if betas can even do mating bites). He feels hands tug tightly on his hair, eliciting a moan from Kazuya. Damn.
“Miyuki,” whimpers Sawamura. “Touch me.”
Miyuki lifts his head. “Where?”
Sawamura takes his hand and places it on – What the fuck?!
“Here.”
Kazuya bites his lip, fighting off a loud moan threatening to escape his lips as he strokes the omega’s clothed length, breathing heavily while he hears the lovely sounds escape from the omega’s mouth.
“Is this fine?” he asks.
“More, Miyuki.” Sawamura tries to pull out his pants. “Please.”
Kazuya curses and tries to gather what’s left of his sanity. He looks at the pitcher’s lower region hesitantly, prying off the hands. Sighing in exasperation, he pulls the pants down, gritting his teeth, and shakily fists the erection in his hand. Kazuya tries not to look while he moves his hand gently – who knows what’ll enter his mind once he gives in to the temptation.
“It’s not enough,” cries out Sawamura, his pleading eyes sending Kazuya into a frenzy. “I need more.”
Fuck it, he’s already done for anyway. Kazuya wets his finger and inserts it on the omega’s entrance, groaning when it sucks him easily. Oh, right. Omegas already have lubricants. Shaking his head for his own stupidity, Kazuya swallows what’s left of his non-existent innocence and pulls his own pants down, taking his cock out and stroking it. Kazuya moans at his own touch. He looks at Sawamura, taking in the omega’s expression, before lining up his cock on the omega’s entrance.
Kazuya pecks the pitcher’s lips before sliding himself in.
Fuck, Kazuya has never felt so satiated before in his life.
Kazuya kisses the omega so hard, swallowing the moans coming from his mouth, as he thrusts himself inside. Blood roars in his ears when he feels nails raking at his back, and his thrusts became faster, groaning when he lifts his head and sees Sawamura’s flushed face staring at him. Kazuya can’t help but love how wrecked the pitcher looks.
Sawamura suddenly lets out a loud cry when Kazuya hits his sweet spot. Kazuya presses his lips on the spot near the collarbone, sucking at the skin and reveling at the warmth coiling inside him.
“Miyuki, I think I’m cumming,” breathes out Sawamura while he moves his hips to meet Kazuya’s length.
Kazuya freezes and lifts his head, stopping his thrusts. “Wait. Fuck, I can’t cum inside you.”
Sawamura opens his eyes and scowls at him. “Why?” he demands. “Why did you stop?!”
“Idiot.” Kazuya purses his lips, eyebrows scrunching. “Do you really want to be a parent this early?!”
Sawamura huffs at him. “You’re the idiot! I take contraceptives, tanuki bastard!”
Kazuya gapes. Oh.
“Now, can you please start moving because it really hurts – “
Kazuya makes a face and thrusts deeply inside the omega, grinning when he sees Sawamura lose his spunk and moan loudly. But the grin slides off his face when the omega tugs him down and kisses him – Kazuya’s thrusts become faster, slamming his hips inside the tight warmth in pleasure. He strokes the omega’s cock as he deepens the kiss, letting himself get lost in the heat, his thrusts becoming more erratic. Sawamura cries out and spurts of white burst from his cock, painting Kazuya’s stomach white. Kazuya closes his eyes as he thrusts one last time, dissolving into the waves of pleasure as he fills Sawamura inside with his own cum.
“Fuck, that was – “
Sawamura whines. “Miyuki.”
Kazuya opens his eyes. “What?”
Sawamura points below him and Kazuya’s eyes widen when he sees the length throbbing again. Kazuya presses his head on the omega’s shoulder, groaning in defeat.
“My stamina will be dead by tomorrow morning. Shit.”
***
Everything suddenly turns into a routine for the whole year.
Sawamura gets into an unpredictable heat. (Seriously, why do his heats have no exact schedule? He keeps getting heats on Kazuya’s most exhausted days too.) Kazuya takes him to his dorm room. They fuck. The cycle repeats until the heat ends.
Kazuya doesn’t know what to make of this. They’re not even dating – he swears one of these days he’s going to snap because the omega keeps on talking to so many alphas on the team. He suddenly wonders if being a beta is the reason why he’s only just his crush’s fuck buddy.
“Why do you look like someone peed in your shoes?” asks Kuramochi, crumpling the can of juice with his hand.
Kazuya sends him his default smirk. “What are you talking about, Mochi-kun?”
“Don’t give me that.” Kuramochi looks at him pointedly. “Having troubles with Sawamura?”
Kazuya keeps his mouth shut in a tight line.
Kuramochi sighs. “I knew it. You know, if you’re so in love with the guy, just fucking ask, will you? He’s an omega addicted to shoujo mangas and disgusting lovesick fantasies. Just do us all a favor and confess. It’s tiring to see your grumpy face.”
Kazuya makes a face. “Why should I? Can’t omegas just learn how to ask themselves? What’s up with that rule anyway?”
“Unfortunately, the omega you’re head over heels for is a fucking romantic. Get it through your thick, stubborn head.” Kuramochi sighs exasperatedly. “Just… Just ask before the whole world gets trampled by pining idiots.”
Kazuya is somehow convinced to reconsider his life choices.
***
“You’re right,” mumbles Kazuya, scratching the back of his neck.
Kuramochi snorts. “Of course I am. I don’t even understand what you both see in each other. I guess both of your tastes revolve around stupidity so moron dating is a given.”
“You’re just jealous, Mochi-kun,” taunts Kazuya, sending him a shit-eating grin.
Kuramochi grunts. “Not really. I’d rather be alone than date an idiot.”
That’s because you’re going to be the idiot in the relationship, thinks Kazuya, but he keeps his mouth shut, not wanting to be the receiving end of the shortstop’s tendency to kill people with his temper.
***
Kazuya struggles to pinpoint why he’s feeling a strange sensation inside him when he watches Sawamura pitch on the mound. He figures it might be his libido playing tricks on him – he still doesn’t want to admit that seeing his crush always send him into a spiral of almost-got-a-boner thoughts.
“Nice ball,” he yells as he throws the ball back to the pitcher.
Sawamura grins brightly at him from the mound when he catches the ball.
Kazuya feels the hot sensation on his gut again. It makes him feel sick.
***
There’s no greatest feeling than winning Koshien with his boyfriend.
Kazuya loves that his last memory of playing baseball is reaching the top – with his ace of a boyfriend pitching the last pitch he’ll ever receive while playing for Seidou, the pitch that strikes out the opponent’s cleanup batter and secures their win. Somehow, Kazuya’s memories of middle school flashes before his eyes – and he thinks the pain he received for training hard and becoming better than his teammates are all worth it.
“We did it!” exclaims Sawamura, hugging him tightly. “We won, Kazuya!”
Kazuya grins and embraces the pitcher back, pressing his face on the slant of his neck. “We did. I’m so proud of you.”
They end up celebrating at the cafeteria in the evening. Kazuya awkwardly says his last speech as the captain – he promises to punish the shortstop howling in laughter later when all are already settled. His mood only brightens when Sawamura follows him to his room, demanding he gives him a reward which, of course, Kazuya is very happy to give.
“Kazuya, move.”
He thrusts roughly and deeply inside the omega, sucking a sensitive spot on the neck. Kazuya nips and bites, lapping the reddening skin with his tongue while he hears Sawamura whine below him. Kazuya feels a strange sensation pooling on his insides and his thrusts suddenly lose their usual strength. Sawamura looks at him in worry.
“What’s wrong?”
Kazuya suddenly feels a strong urge to ravish the body below him. Mine, mine, mine – Wait, what the hell is happening to him? Kazuya’s vision blurs and he feels his surroundings getting hazier. A strong scent of lemon and sandalwood fills the air – Kazuya’s stomach clenches at the scent. He grits his teeth as he feels himself sinking in the whirlwind of thoughts suddenly flowing inside his head.
“Kazuya.” Sawamura cups his hand on Kazuya’s face. “What’s happening?”
“Wait, Eijun. I feel like I’m getting sick.”
Sawamura bites his lip and Kazuya finds it so enticing. “Maybe we shouldn’t do this now? You should probably rest.”
Kazuya groans, the scent getting even stronger, filling his senses into overdrive. His mind keeps splitting into words of mine, mine, mine… Kazuya grasps the side of the bed tightly to calm himself.
Kazuya loses himself on the sudden heat filling his body, and he feels his cock throb inside the heat.
Mine, mine, mine, mine –
Kazuya snaps.
“Fuck!” yells Sawamura when Kazuya suddenly roughly thrusts into him, pounding harshly as if a wild animal just possessed him. Kazuya doesn’t know what he’s doing – fuck, he doesn’t even know why his body is suddenly acting out of his own accord. His mind is even more out of control now. Why the fuck is he getting possessive thoughts all of a sudden?!
Sawamura sobs when Kazuya bites on his neck hard, licking at the sore spot after. “K-K-Kazuya, more!”
Kazuya lifts his head and kisses the writhing omega roughly, feeling even more turned on from the filthy sounds coming out of Sawamura’s mouth. He sees the omega shudder when a part of him is suddenly turning bigger… What the hell is happen –
Kazuya growls and grabs the omega’s chin, looking at him darkly. “Why do I smell Furuya Satoru on you?!”
Sawamura whimpers. “Kazuya, what are you – “
Kazuya thrusts on the omega’s sweet spot, unraveling him. “Answer me, omega. Why can I smell him on you?”
Sawamura shakes his head, tears flowing on his face. “We just talked. You were with us, Kazuya.”
Kazuya pulls the omega into a rough kiss, biting at his bottom lip harshly. “Good. Because you’re mine, Eijun. Mine.”
Kazuya smirks in satisfaction as he drives his hips into deep, violent thrusts on Sawamura’s sweet spot, watching the pitcher cry out and whine below him – he loves to see his omega look so fucking gorgeous for him like this.
“Who do you belong to, omega? Tell me,” Kazuya commands, moving his head to suck near that delicious scent filling his nose.
“You, alpha,” says Sawamura deliriously, his voice shaking. “I’m yours.”
With an approving noise, Kazuya thrusts even more roughly, and Sawamura cries out, his cock spilling cum. He groans as he feels the heat around his length tighten and his seed fills the inside fully. Kazuya sinks his teeth at the omega’s neck, reveling at the beautiful sounds escaping his omega’s mouth.
Kazuya grins wildly when he feels his cock get bigger, and he knows his omega is his forever.
“We’re mated for eternity, Eijun. No one can take you from me now.”
***
The doctor pushes his glasses up. “We call this phenomena alphafication. It starts when a beta spends a lot of time with an omega on their heats. Then, the beta suddenly starts feeling differently in his body. Patients have reported a strange heat or sensation showing up out of the blue for no reason. You could even mistake it as you getting turned on, but it’s the hormones inside of your body suddenly shifting.”
Kazuya blinks and purses his lips. “And that happens to all betas?”
“Not really. It only happens to betas with at least 10% alpha blood on their DNA. That alpha percentage gets awakened and the beta slowly turns into an alpha.” The doctor hands Kazuya a stack of papers. “Here. Take this. It’ll help you learn better about the changes your body is undergoing. You might feel a strange possessiveness whenever your partner is around another alpha and remember, alpha ruts are harder to manage than beta ruts so make sure to study more about it.”
“Fuck,” mutters Kazuya.
“Another thing. You might want to talk to your omega partner about this.” The doctor gives off an odd smile. “This only happens when your omega partner strongly desires for you to become an alpha and only if he replaces your beta rut pills with alpha rut pills continuously. Your body shifted because of the pills inducing some changes.”
“What?!” exclaims Kazuya incredulously. What the fuck. What the fuck.
***
“Wakana, how are you doing?” asks Eijun cheerfully, placing the phone on his ears.
Wakana laughs. “I’m good. How about you? Did it work?”
Eijun cackles. “What are you talking about?”
Wakana lets out an amused snort. “You know what I’m talking about. The thing you tried should’ve had some effect soon.”
“Well…” Eijun grins excitedly. “Let’s just say I’ll probably have my ass ruined by the time my boyfriend gets back from the doctor’s office.”
