Sigmate | AtsuOiHina Omegaverse AU

Chapter Text

"Please meet our new club member, also the twin of our honored member Osamu-kun, Miya Atsumu." Shirabu introduces Atsumu to the whole club members. The crowd begin to clap, welcoming Atsumu to the club. After greeting some of the members, Atsumu quickly find his brother. Osamu is taken away from his circle and getting dragged to the corner of the club room.


"What theㅡ"


"Do they not taking any suppressant? Ughh its suffocating me." being born as a definite dominant alpha, Atsumu can't help but to be extra sensitive with the scents. The overlapping scents are too strong, it is disturbing.


"Come on, you were the one who asked for my help to search for a perfect dominant omega for you. This is it. The club where we find future connection, future 'mate'. I've been here for months, you'll handle the scents well soon. It is quite overwhelming at first." Osamu chuckles, leaning on the wall. Atsumu sighs, can not believe that he is stucked in the crowd. It's not the people that are too crowded, but the scents. Most people in the club seem to be releasing their scents to show off their dominance, how strong they are. Ofcourse, the dominant alphas are the one that having the outstanding scents among all the members. 


"Can I stop them? I don't mind using my scent to the max if that can stop these bastards. This is not a fucking mating match, for fuck sake!" Atsumu nags, facepalming himself. Osamu pats his twin's shoulder.


"You know the consequences if you do that for this, right?" with a sly grin, Osamu reminds Atsumu to control himself. Being born as twin, both of them always fight to be the strongest. As they grew up, Osamu knew and accepted the fact that Atsumu is an alpha with stronger characteristics. To him, his brother is born gifted. He can quickly catch up with everything that he's lacking. As for Osamu, it's not like he's not strong at all, he have strength in other fields. Although it's not as obvious or as something that can be shown off, but he's grateful for whatever he has now. Atleast, he still thinks he's the winner when it comes to their looks. 


"So, what do you usually do in this club?" Atsumu shifts his eyes to Osamu, not taking any interest to the crowd. He hopes that he can ignore the scents as soon as possible before he going mad. It's not that he's sick of crowded place, but the scents are just too much. 


"Hmm? Well, socializing? This is richy kids club, to be exact. They sometimes manage some party or events. I haven't join any of them. I heard they're planning on having 3 days party on a cruise soon. Since you are here, wanna join?" Osamu takes a glass of wine from a butler who suddenly pop out of nowhere and offer them some drinks. Atsumu's body suddenly shivers, as if there was a cold breeze blew behind him. His eyes quickly glances to the butler kid, who seems attracting others female omegas and some alphas to him. His eyes narrowing, a natural irritation comes whenever he sees someone getting too much attention. Osamu turns his head to look at what makes Atsumu frown and he chuckles. Another win for him, he's more mature than Atsumu, that's what he thinks.


"Who's that? Looks like a popular boy, huh?" Atsumu points to the orange-haired butler.


"Hinata Shoyo, an alpha. Not look like one, but he's a dom alpha." says Osamu simply.


"Didn't you smell it? His scent, it's different. Totally different!" Atsumu had his eyes on Hinata and not even want to atleast cover himself from being obvious. Atsumu thought for some seconds that the scent was rather spicier than normal alpha's scent.


"Hurmm? No, I think. Maybe you're just being extra sensitive? What? Anyways, this wine tastes nice, not bad. I shall ask the name from Wakatoshi-kun later." Osamu takes another sip from the glass. Atsumu stares at Hinata, as if he's hoping for the latter to realize it. 


Hinata, from the other side of the room, actually does realize someone is staring at him but he can't be sure who's it. The crowd of females approaching him is not helping at all. Although he's used to it, but he's not here as the member of the club. He's a butler. He isn't from the wealthy family. He works here to pay for the academy he's in, and for paying rent and other stuffs as well. But somehow, since he started to work here, he's getting all the attention. Maybe not all, but quite alot. In that kind of situation, it is expected that there will be some alphas having grudge on him. Dead threat is nothing uncommon, he even got into a gang fight. His friends told him to quit but this is the only job that pay the highest. $30 per hour, hell yea! Fighting others with his willpower is not a problem, not at all. But living in untruth is the problem.


He IS NOT an alpha. 


And to make it worse, he was born as a rare dynamic of all, a dynamic that people nowadays thought it was extinct.


He is a SIGMA.










Shoyo's POV


It's almost 3 hours, my work will end soon. Today I will get my pay! Nothing can beat the happiness that came from getting your salary, that applied in most case. 


"Hinata~ You look great today? Did you perm your hair?" Lev, a dom alpha who I remember he joined the club since a week ago, suddenly came and ruffles my hair. The heck? I politely take a step back. 


"Ah no no. I didn't. I was rushing this morning and forgot to comb my hair after I dried it." I said, but that makes the other girls praise me more, saying that my natural curly hair is a solid charm of mine. Are these omegas crazy? I have never believe them since Suga-san, my supervisor told me that the omegas here are all sugar-coating their words to attract alphas. It is not them to be blamed, though. The hierarchy for the second gender is very cruel, so I kinda understand why some of them are desperate to find a great mate. The problem is, I'm not on their level. Somehow I regret *trading myself to be an alpha, it was useful during childhood, but not now. Not when you're an adult and finding a long-life partner is the top priority.


*when sigmas were kid and able to understand about their second gender, their parent will do a meeting with the whole family members to do a trade. a trade is when you choose your second gender for the public. the options are only alpha and omega. after trading, the child will begin to study and familiarize themselves with their choice for two weeks, before they privately take a gender test at the hospital. since sigma is believed to be extinct, there is no data about sigma in any hospital, so the technology machine used for the gender test will choose the major points to give out result. ( hinata chose dom-alpha. after two weeks, he went to do a gender test and the result was all pointing to his dom-alpha characteristics. that's how he is known for being a dom-alpha )


"Hinata, are you okay? You look tired. Eh waiㅡ which one of you are in heat? What the hell get out from here, now!" Kogane who just passed by some people that are crowding me, smelled the sweet scents. Everyone look confused and carefully distancing each other. And I just realized that I'm getting weak all of sudden. My head is spinning and somehow it's getting hot in here? Or is it just my body?






I forgot.



This month is my heat month!



"Ko-Kogane! Please tell Suga-san I'm leaving early. I just remember that Na-natsu told me she's in heat this week and I need to take care of her, so I need to go now. Bye!" quickly, I sprint and squeezed myself between the crowd to leave the clubroom. Fuck, I really fucked up.


I run into the staff room, where my bag is supposed to be. Desperately I open the pouch from my bag to get my heat suppressant.


"Quick, quick. Before anyone comes," my eyes keep looking at the door, but my hands can't seem to grab the important thing. I glance to my pouch.



Double fuck.







I forgot to refill my pouch with the heat suppressant. Shit! What am I supposed to do?! I can't breathe properly. I need to leave this place as soon as possible. If I'm trapped with anyone, worse that it is with an alpha, I am doom. I'm totally doom.


I threw my pouch inside the bag, quickly zip it and ready to leave. This is totally a super unlucky day for me. If I can make a category for it, this day will win by default. I'm in heat, I forgot to refill my suppressant and now I need to use the stairs from floor 17 to go to the lobby. I can't use the elevator, nope, that's hella dangerous. Anything can happen in that small moving space. 


Thank god that I'm fast, or else I might attract some people from different floor to the stairways. Almost reaching the lobby, almost believing that being fast is beneficial at this moment, I tripped my feet and fall on someone who's on the way. 


"Arghh fuck!" the person below me rub his head after hitting the wall. Strange, my body becomes hotter and I'm turned on. He's an alpha. A dominant one. 


"Huh?! You are the butler from theㅡ" the guy below me quickly cup his mouth and push me. I want an alpha, so bad. Without realizing, I started to point out the good features of the blond guy infront of me.


His hair is silky blond, stylized as undercut. His eyes are shining with striking yellowish hazel in color. His nose is perfectly shaped and his mouth, the lower part is thicker. I want him, my body wants him. I can sense his pheromone. He wants me too, right?


"Fuck! Are you the one releasing this pheromone? This is too strong. Stay away from me!" The blond guy tried to stand up, but his legs became wobbly. I knew that, I did that. My pheromone did that. I can't control anymore, I want him to fuck me right now.




Wake up!


Fight this heat!


You can't let anyone find out about you!


The voice inside my head begin to knock a sense in me. I grab the steel handle of the stair, hardly trying to stand up. I need to leave this place. God please!


"Itㅡit wasn't me. I'm affected too." there, I guess that's enough, right? I push myself to walk downstairs, just a few floors to the lobby. I can make it.
