Yunho bit his lips as he look over to Mingi and one of the trainees, talking happily with each other and Yunho can see how the trainee seems to give off a subtle flirty scents towards Mingi and Mingi seems happy inhaling the omega sweet scents as his own alpha pheromones dancing around the area, mixing together with the omega's scents.

He lowered his gaze to his hands with a pout and a sad sigh.

How I wish I'm an Omega.. Yunho thought as he look around in the studio and he felt like crying as he watch Hongjoong, the head Alpha of ATEEZ cuddling with Seonghwa, the Omega and Luna of the pack, Hongjoong's mate, San, an Alpha, playing around with his mate, Wooyoung, an Omega as Jongho, the youngest Alpha in ATEEZ, happily feeding his Omega, Yeosang.

You see, Yunho is the only Beta in the group and he was one of the few Beta residing in KQ or even in Seoul. Betas are very rare but they also seem to be the lowest in hierarchy in this world right now. Why? Because being a Beta means you are incapable of bearing a pup or breeding an Omega thus they are considered the 'useless' one in the society.

They are usually used for slaves or sex slaves for whom that doesn't want to end up with a pup.

And Yunho hates being a Beta so much that he cried every time he thought about it. Everyone in his family thought that he would be an Omega just like his other older siblings as his family are the famous 'all Omegas siblings' family but they were very disappointed with Yunho when he presented as a Beta right on his 17th birthday, the age where their 2nd gender presented.

Yunho was excited that day, on his 17th birthday, that he would finally be presented as an Omega like everyone expected him to but when nothing happened that night, until the next morning, Yunho's world came spiraling down the drain after that. His family disowned him that day, kicking him out of the house as they were ashamed that Yunho turns out to be a Beta and Yunho wanders around aimlessly for about a week, sleeping in the Sauna and trying to find a job but they all reject him as he is a Beta.

Until one day, a nice Alpha by the name of Eden, took him in under his wings, giving him shelter and food. He even put Yunho in KQ as the Beta has a talent for dancing and his voice is sweet like honey. After a year in KQ, Eden put him with the rest of ATEEZ and he had to stay in the dorm with all of them.

Yunho was reluctant at first, to stay at the dorm, fearing that they would hate him and bully him like he had to face everyday while training in KQ but surprisingly all of them were nice to him but they also didn't really dote on him so much. Yunho can only be grateful that they didn't beat him like he had to endure for a year while training.

Yunho felt lonely and to make it worse, he had a crush on the only single Alpha left in ATEEZ, Mingi. While Mingi is being nice to him, he also tends to flirt with every Omega that wants to try with him in hope he can find his mate but for now, there is no one and for now, Yunho can breathe a relief breath.

He can't imagine what will happen to him when Mingi finally finds his mate.

Oh? He forgot to mention. Betas doesn't have a mate. They are cursed to be alone until they die.

They will only find their mate if both of them are presented so Mingi thinks that his mate may be younger than him and he can only wait and Yunho hopes that the day will never come.

"Hey Beta, would you be a good boy and buy me food? I'm starving."

Yunho blinks as the Omega trainee that was flirting with Mingi went up to him and Yunho quickly lowered his gaze to the ground and was about to stand up when San stopped him from doing so. "Go get your own food yourself, trainee. Did you forget Yunho is a member of ATEEZ? He won't be slaving to you trainees anymore." San growls making the Omega submit and rush out of the studio while Yunho bit his lips, trying to calm himself down.

Yunho can feel his anxiety rising after he briefly glanced at the fleeing Omega and saw that the Omega gave him a glare and he knew he would be in trouble if the other trainees found him alone without any of ATEEZ with him later on.

"They are still bullying you Yunho ah?" Seonghwa said as he approached the Beta and Yunho could only shrug and give him a small smile. "It's alright pup, they will stop one day." Seonghwa said as he caressed Yunho's hair and Yunho closed his eyes and let out a tiny purr. He always loves it when his members caress him, especially the Omegas but he won't demand it as it would make their Alphas jealous. They would be fine if Yunho's an Omega too but they will feel jealous because Yunho is a Beta.

Things are going better each day until one day, his notebook went missing. The notebook where he always pours his heart out and talks about his crush on Mingi. Yunho frantically searches his bag and around the studio, even going to the other studios to search for it but he can't find it.

Yunho sighs softly and clenches his hands together to stop it from shaking as he goes back to the studio to practice with ATEEZ. They practiced for 8 hours and right after the last dance ended, the Omega that flirted with Mingi all those weeks ago came into the studio with several other trainees.

Bearing his notebook, Yunho widened his eyes as he started to tremble as the Omega and his friends went to Mingi, while smirking at Yunho.

"No.. Please no.. He will hate me after this..." Yunho said to himself but he can't seem to move his legs so he stayed rooted to his place and watched the event unfold with wide eyes.

"Sunbae-nim~ Look at what I found! You should see this!"

"Hm? What is it? Wait. Isn't that Yunho's notebook? Why do you have it?" Mingi said frowning at the Omega and his friends.

The Omega faltered a bit as Mingi seems to raise his voice a bit but he is determined to watch the Beta fall. It was supposed to be him to be the last member of ATEEZ but no, Yunho had to come and the higher ups seems to favor him more as his talent is better than any other trainees.

"The BETA had the nerve to have a crush on you sunbae-nim! That is absurd! He keeps writing saying that he hopes that one day he can be your mate! Without the system! That is ridiculous, sunbae and you know it don't you?" The Omega said making his friends snickers while the others in the room gape at Yunho.

Before Mingi huffed and snatched the notebook from the Omega. "Yeah? And? It's not wrong to have a crush on someone. You are not a Beta so you don't know how they're feeling. Don't speak so highly just because you're an Omega. We Alphas can still manhandle you, you know? Just stop bullying him." Mingi said as he walked to the shaking Beta in the room and softly handed him the notebook.

Yunho took it with shaky hands, his face red and he's on the verge of crying but he held it in as best as he could. The Omega frowns before he glares at Yunho and walks out of the room, his friends following him.

Yunho had his gaze on the floor, feeling ashamed now that everyone in ATEEZ knew about his secret crush on the single Alpha. Mingi ruffles Yunho's hair softly as he speaks. "It's alright Yunho but I'm sorry that I can't be what you want me to be. I do have a mate out there somewhere so I can't really abandon him or her for a Beta.. I'm sorry." Mingi said softly and Yunho shook his head. "It's alright. Forget about it please." Yunho said softly and Mingi can only give him a small sad smile.

Everything becomes normal again after a few weeks but ATEEZ now makes sure that Yunho won't be alone when they are at KQ just to make sure no one bullies him again.

Yunho's 21st birthday is just around the corner, in 1 week to be exact but Yunho can't find it in him to be thrilled about it and he just hopes that day will be gone quickly.

Yunho woke up feeling a bit off. He stumbled from his bed and nearly crashed his head on the dresser but he managed to avoid the dresser with his reflexes and stumble down to the floor instead. Yunho groans as he hears a knock and someone opens his door. In the dorm, only Yunho and Mingi had their own room as the other shared it with their mates.

"Pup? What happened? Are you alright?" Seonghwa said as he peek his head inside as Yunho pushed himself off from the floor. "Yes. I'm alright hyung. Lost my footing that's all. Sorry for worrying you." Yunho said and Seonghwa tilted his head as he sniffs subtly but nodded his head afterwards.

"Go shower. I think the bathroom is free right now." Seonghwa said and Yunho nodded his head.

After the shower, Yunho wears a big oversize sweater that actually manages to make him look small before he heads to the kitchen. He sits at the table and frowns a bit when everyone stops talking once he's in the room.

"Did you use some kind of perfume Yunho ah?" Wooyoung said as he sniffs the older and Yunho tilted his head. "Hm? No? I'm not wearing any perfume right now. Why?" Yunho asked and Wooyoung looked at him in wonder. "You smell sweet. Like strawberries." Wooyoung said and Yunho frowned. "Huh? I do?" Yunho said as he sniffs himself. "I don't smell anything though?" Yunho said and suddenly the Alphas narrowed their eyes towards Yunho making Yunho squirm in his seat.

"W-what's wrong?" Yunho said and Hongjoong speaks first. "Are you trying to be an Omega, Yunho ah?" making Yunho widen his eyes and frowns. "What? What are you talking about hyung?" Yunho said. "Did you buy an Omega scent and spray it on you? This sweet smell is definitely coming from you and Betas does not have any scents." San said.

"You really don't have to try to be an Omega, Yunho hyung. You're an amazing Beta anyway." Jongho said softly and Yunho frowned again, confused. "I'm not trying to be an Omega though? What are you guys talking about?" Yunho said and suddenly Mingi raised his voice towards Yunho.

"Don't play dumb Yunho. This smell is definitely coming from you. I get it if you want to be an Omega but isn't this too much? Lying to your members?" Mingi said in his Alpha voice making Yunho whimpered slightly recoiling himself in his seat as he shook his head. "N-no. I swear I'm not. I don't even underst-" Yunho tried to say but he stopped when all the Alphas growled at him.

"Yunho. Stop the act. Now." Hongjoong said in his Alpha's voice and Yunho burst into tears as the command made him submit but his body didn't know what to do as he didn't lie and it's hurting him physically. Yunho wrap his arms around his waist as he sobs but they thought Yunho was trying to fight back so the Alphas grew angrier.

"If you want to keep being stubborn then you'll be punish Yunho. Go to your room until we say you can come out again and think of what you've done while you're at it." Hongjoong said, still in his Alpha's voice and Yunho can't do anything but to obey it. He weakly stands up, his arms still wrap around himself as he stumbled to his room and he flop down on his bed, sobbing quietly.

Why does everything have to happen badly when it's on my birthday? Yunho thought sadly as he whimpered and the wave of pain surged throughout his body because of the Alpha's rage and his body didn't know what to do so he had to endure the pain for now.

"Aren't you guys a bit harsh..? Alphas..?" Yeosang said quietly. "Yeah.. It doesn't look like Yunho is lying though.." Wooyoung continues and the Alphas huff. "Then can you explain the sweet scent? He would be fine if he cut his act right away but he fights back instead. So he has to be punished. It's the pack rules. You Omegas knew this." San said further.

The Omegas can only sigh softly.

"Come on. Practice time. I'll tell the trainers that Yunho is sick or whatever." Hongjoong said and they all stand up, heading to KQ leaving Yunho in the dorm alone.

"Hyung? Will Yunho be alright? I'm worried.. He looks like he was in so much pain when Hongjoong hyung commands him.." Yeosang said as Wooyoung nodded and Seonghwa sigh softly. "We'll know when we get back later today pups. If he is lying, he would drop the act soon and he won't be in pain anymore. But... if he's not lying and he was being serious about not knowing what we're talking about.. then he would still be in pain when we get back.." Seonghwa said quietly as he can't shake the feelings that something is not right but they had to obey their Alphas so he can't do anything right now.

Seonghwa only hopes that Yunho is actually lying.

Which Yunho is not.

Yunho's breathing has become shallow and quick after 2 hours as he lay limply on his bed. He's becoming lightheaded as he didn't eat anything that morning and the pain is taking a toll on his body, making him weak. Plus, his stomach now keeps getting cramps especially in the lower area and Yunho just wants all the pain to stop.

--

"I'll go check on Yunho." Seonghwa said as soon as they entered the dorm that night. Seonghwa then went to Yunho's room and he opened it only to be swarmed with strawberry scents and Seonghwa frowns as he quickly became anxious.

Seonghwa closed the door quickly as he approached Yunho on the bed. "Pup..?" Seonghwa said as he sat on the bed putting a hand on Yunho's waist and he widened his eyes when he felt the younger one trembling violently under his touch. Yunho's eyes are closed but Seonghwa can hear how Yunho's breathing is quick and erratic.

"Yunho??" Seonghwa said as he started to panic as the younger was not responding to him. Seonghwa quickly put an arm under Yunho's neck as he turned the younger over and only then Yunho weakly opened his eyes. "L-luna..?" Yunho mumbled weakly and Seonghwa nodded his head as he thread his fingers on Yunho's locks and he gasped a little when he felt the unusual heat radiating from the younger.

"Yes, it's Luna, pup."Seonghwa said softly and Yunho whimpered weakly. "M-make it s-stop.. P-please.. It h-hurts.." Yunho said and Seonghwa shouts.

"ALPHAS! GET YOUR ASS IN HERE RIGHT NOW!" Seonghwa shouts in his Luna's voice making the Alphas rush to Yunho's room, the Omegas tailing worriedly.

"What happe- Fuck! Is he still in pain??!" Hongjoong said as he rush to the bed. "Yes! Drop your commands now! All of you!" Seonghwa said and the other Alphas quickly went to the bed as Hongjoong press his hand on Yunho's forehead.

"You are no longer to be punish, pup." Hongjoong said as the other Alphas nod in agreements. Yunho gradually stops trembling as the pain diminish but he can't help but to whimper when his stomach cramps again and wrap an arm around it.

"Call Eden hyung, we need a doctor too." Hongjoong said and Yeosang is quick to pull out his phone and call Eden.

"Pup? What's going on?" Hongjoong said softly and Yunho starts crying again. "I d-don't know.. I s-swear.. What's happening t-to me..?" Yunho said in between his crying and the other can only watch helplessly.

Mingi then went near Yunho's head as he sat on the bed, gently hauling Yunho up and pulling him closer until Yunho's back met with his chest. Yunho limply lay his head on Mingi's shoulder as he tried to take a few breathers. Mingi runs his hand on Yunho's chest gently as they wait for Eden and the doctor to come.

--

"He just presented." the doctor said and everyone else in the room minus Yunho, who is currently half-conscious, gape at the doctor.

"W-what?! But he's 20- wait.. today is.. 23rd!" San said and the other gasp.

"It's his birthday! He's turning 21 today!" Hongjoong said.

"But still.. What do you mean by he presented? He already did when he was 17." Mingi asked, still in the same position as before, Yunho limply lay on his shoulder.

"What was he?" the doctor asked calmly.

"A Beta." Eden answered and the doctor hummed. "As you all know, when a beta is presented, nothing happens. Right?" the doctor said earning nods from all of them. "But it can also mean that he did not present at all at the time. It's rare but it does happen. We called them the 'late bloomer'." the doctor explained and all of them widened their eyes at this information.

"He's an Omega. The sweet scent is enough to confirm this and he also said that his stomach keeps cramping right?" the doctor said and Seonghwa nods. "It's because his heat finally comes, 4 years late. It can be overwhelming for him so I suggest just helping him go through his 1st heat carefully. No sexual intercourse, at all. Not even with toys. He won't be able to feel the pleasure anyway, only pain as the accumulated heats that had been suppressed for 4 years gushing out. He will have this fever until his heat ends and he will need your help with it as he will be weak most of the time. Keep him hydrated and feed him." the doctor said and everyone nods their head.

"You can call me if you have any questions. For now, let him rest. Put a warm towel on his stomach to help him with the cramps and a wet towel on his forehead and necks, for his fever. That's all. Give him the medicines on time." the doctor said before he left the dorm with Eden as Eden told them to take care of their newly presented Omega.

Mingi stayed by Yunho's side that night.
