Worthy of your love

Summary:

“M-Mimosa…” 

She hurried to the bedside, seeing Asta’s flushed face. Tears and sweat started to mix together. “What… W-What is happening.. to me?” Asta asked weakly, breathing heavily.

Mimosa froze, her blood ran cold as the realization struck her all at once.

“Oh, Asta…”

This might be Asta’s first heat.

OR

Asta having his first heat and Yuno being protective.

Work Text:

“Oh, Noelle and Asta! Hi!” Mimosa waved with a smile on her face.

 

“Hey Mimosa!” Asta shouted, happy to see the trio.

 

Mimosa, Klaus and Yuno were on their way to the wizard king’s office, to give a report and assumed Noelle and Asta were doing the same.

 

“It’s so nice to see you two again.” Mimosa softly said, trying to hide the blush on her face. She knew Asta was an omega like herself and that she was supposed to be with an alpha, but couldn’t help having feelings for the fellow omega.

 

A conversation broke out between the group, except Yuno who watched from the sideline.

 

“Oh Asta, are you feeling good?” Mimosa changed the conversation, walking closer to the teenager and putting her hand on his forehead. Every eye fell on him. Mimosa noticed Asta didn’t look so good. She saw his face flushed and some sweats “You seem a bit warm.”

 

“Hehe, I guess the weather is warm today.” Asta tried to play it off.

 

“It’s autumn.” Noelle commented. “Don’t tell me you caught a cold from staying out so late. I told you to wear something warm, Stupidsta.” 

 

“Yeah yeah.” Asta tried to brush off, used to people nagging at him, before the stars in his eyes returned. “Anyway, tell me what happened after you found the hideout!”

 

The conversation kept going on, but this time Asta didn’t engage as much. Which everyone noticed but didn’t comment, thinking the shorter teenager has gone through a lot. The group kept walking, getting closer to the office and Yuno leading the way.

 

“Asta!”

 

Yuno’s head snapped around at the sound of both the girls shouting Asta name. He spotted a shorter teenager on the floor, slumped against Mimosa as struggled to catch his breath. 

 

“Asta?” Yuno walked closer, feeling an uncomfortable feeling settle in his stomach. He saw how Klaus kneeled on the floor, helping Mimosa to hold Asta up.

 

“Warm…” Asta groaned, breathing even more heavier as sweat appeared. “It’s so… fucking warm and painful.” 

 

“Asta,” Klaus leaned closer to Asta, nuzzling his face into his neck. “You smell so good.”

 

“Get away from him!” Water appeared out of nowhere, throwing Klaus forced away from the girls and the boy in pain.

 

Something clicked in Yuno’s head. Klaus is an alpha, like him and Noelle while Asta is an omega just like Mimosa. Yuno’s grimoire started to float in the air, summoning Bell.

 

“We have to get him out of here, he is in heat!” Mimosa panicked, feeling scared for the boy. 

 

Wind started to gather around, the girl’s head snapped to the culprit. 

 

“Give me Asta.” 

 

“As if, peasant. You think you're worthy of him?” Noelle stood her ground, wand pointing towards him. If Yuno wasn’t busy getting Asta in his hold, he would say he was impressed that Noelle could resist Asta’s scent.

 

His scent, God his scent was so good.

 

“Don’t cry when I beat your ass.” Yuno said before summoning the wind and attacking the royal girl. 

 

Water and wind forcibly fought each other, in the middle of the palace. It attracted unwanted attention.

 

“What smells so good?”

 

“It's coming from that omega boy.”

 

“He is in heat? Hehe, maybe he needs an alpha to satisfy him.”

 

Something snapped inside of Yuno as a feeling of panic rose.

 

“Playtime is over.” Three words left his mouth before causing Noelle to fall on the ground, bruised and bleeding. Yuno stalked towards his target that was held by a scared Mimosa.

 

Control, Yuno thought as he summoned a gush of wind that turned into transportation. He stood in the front, protective of the two omegas, getting ready to cast another spell if it was needed.

 

“Y-Yuno?” Mimosa was both anxious and relieved. They were getting away from the crowd of alphas but worried where the alpha was taking them. Yuno didn’t reply to her, but once her panic settled, she could see his hand was trembling. She wondered if it was out of self-control or anger.

 

She spotted a familiar building as Yuno started to slow down. It was their base.

 


 

“Have you ever been in heat before?” 

 

Yuno wasn’t the type of person to ask personal questions, but it was needed in this situation.

 

“Yes, I have.” Mimosa watched as Yuno carried Asta to his bed. Asta squirmed in his arm, complaining about the pain and dreadful warmth. 

 

“Y-Yuno..” Asta breathed heavily, struggling to sit up but lacked energy.

 

“Shh… you’re safe now., Asta.” Yuno murmured gently. “No one will hurt you here.”

 

Mimosa watched as Yuno carefully eased omega onto the bed. He brushed his fingers through Asta’s hair, cupped his cheek with a tenderness that was unspoken devotion. This was a side of Yuno only meant for Asta.

 

Envy flickered in her chest, Mimosa longing for someone who would look at her with the same care. But at the same time, she felt proud seeing Yuno didn’t let his own desire control her, especially when a vulnerable omega was involved.

 

“Mimosa will take care of you, and I will be outside to protect both of you.” Yuno whispered, feeling Asta relaxing under his touch. The boy could only whimper, overwhelmed with all the new feelings. “Does that sound good?”

 

Asta nodded, enjoying the gentle traces of the fingers. “Y-Yeah I.. trust you.” 

 

Yuno kissed the crown of Asta’s head, an unspoken promise that he wasn’t alone and unprotected.

 

“Take care of him.” Yuno said, who sounded like he breathed a bit heavy but Mimosa didn’t comment on it. “I’ll be outside.”

 

With that, Yuno left the room, leaving the two omegas alone. Mimosa finally allowed her shoulders to relax, she knew by now that Yuno wouldn’t hurt Asta but she couldn’t help feeling tense.

 

“M-Mimosa…” 

 

She hurried to the bedside, seeing Asta’s flushed face. Tears and sweat started to mix together. “What… W-What is happening.. to me?” Asta asked weakly,  breathing heavily.

 

Mimosa froze, her blood ran cold as the realization struck her all at once.

 

“Oh, Asta…”

 

This might be Asta’s first heat.

 


 

 

Yuno collapsed against the wall outside the room, sliding down until he hit the floor. He gasped for air, as if he had been in the water for the last hour.

 

He felt like he could finally breathe and relax now that he was outside, away from Asta’s tempting scent.

 

“Damn…” 

 

Asta was in a vulnerable state and he put all his trust on his friend, his friend who was imagining dirty images of him. Could the shorter boy be more naive?’

 

The hairs on the back of his neck prickled.



Yuno felt the presence of fellow comrades before seeing them. Asta’s scent must be attracting other alphas. Yuno made sure his presence was known, by his magic and scent, not letting anyone touch Asta.

 

His Asta.

 


 

 

“Well fuck, the kid is really in heat.” 

 

Yuno stood up, his grimoire flying as he saw three familiar figures come through the portal. His shoulders relaxed, when he realized it was Yami, Finral and Sister Lily.

 

“Yuno!” Sister Lily came rushing to the taller teen, cupping his face in her hands.  “Are you ok?”

 

“Better state than the idiot.” Yuno, as always, had to act cool. 

 

“No one has claimed the brat?” Yami interrupted the reunion. It was then Yuno noticed him holding a basket full of different things.

 

Yami and Finral are omega, like most of the Black Bulls members, except Magna, Gauche and Noelle. If Yuno is going to be honest, he couldn't think of a better squad for Asta to join, if you ignore the fact all of them needed a whole team of therapists. 

 

“As if I would let any.” Yuno clenched his fist. “Mimosa is inside, helping him.” 

 

“Oh, what a relief.” He could see Sister Lily had been crying, by the red eyes and dried tears mark. He noticed Yami and Finral also relaxed their shoulders. 

 

“I just don’t understand. Asta has a heat suppressant implanted in him, why didn’t it work.” Sister Lily asked loudly, that has been the question Yuno wondered.

 

“Ah, I think I know why, hehe.” Finral interrupted the conversation. “When we were at the Forest of Witches last week, Asta was able to enter a new state with the help of his sword. Asta said something about the anti-mana flowing through his whole body. Maybe it interfered with the heat suppressant since-

 

“It’s made of mana.” This time, Yuno interrupted. “Shit.”

 

The current heat suppressant most people used were made of mana, very few were made without mana and even fewer people used it. Which meant, Asta had to use the ones made without mana, but that wasn't the biggest problem. The problem was that Asta didn’t realize his medicine was not working and he could have had heat anywhere. Yuno was just lucky being present at the right time and place.

 

The thought of some other Alpha being near Asta and touching his Asta, made Yuno’s blood boil.

 

“Damn, it could’ve ended real bad if Mr. Cool wasn’t there.” Yami inhaled the smoke from his cigarette, looking unbothered as always.

 

“Yeah, you did a good job Yuno.” Sister Lily praised him, something Yuno didn’t feel like he deserved. 

 

“I brought Asta some stuff he might need for his heat..” Sister Lily added, as Yami came forward and gave her the basket he had been holding for her. It had a box of food, drink, some herbs and a couple of clothes. Yuno could smell some of it being from his family back in Hage and others being from the Black Bulls. It was one piece of clothing that was annoying him especially.

 

Yuno took off the cape he was wearing, thinking that Asta should be surrounded by his smell, not a certain silver haired girl. “Give him my cape too.”

 

“Thank you, Yuno. I’ll go inside and help Asta. Protect us meanwhile.” Sister Lily gave him a reassuring smile.

 

Yuno opened the door for her, not glancing inside the room. If he saw Asta, he would definitely lose control this time. 

 


 

Three days have passed since Asta went into heat for the first time.

 

Mimosa and Sister Lily were the only people that went in and out of the room, making sure the boy didn’t go through his first heat alone.

 

Yuno had mostly been outside, making sure no other alphas could come near. Noelle appeared and said she wanted to stand guard, not fully trusting the taller teen. It almost ended in a fight if it weren’t for Yami who interfered.

 

Yami and Luck had been the two other omegas that stood in guard, when Yuno needed to take a break and sleep.

 

“I think it’s soon over.” Sister Lily said when she left Yuno’s bedroom together. “He will probably need a couple of days to recover. The first couple of heats are the worst.”

 

Finally, Yuno thought. 

 

“I need to go back to the church soon, but first I will meet up with Vanessa and we will try to find other non-magical solutions for Asta.” Sister Lily sighed. “But us two and Mimosa agreed that maybe the best thing would be for Asta to be off any heat suppressant for now.” 

 

“That sounds good, thank you Sister.”

 

“We are family, there is no need to thank me.” Sister Lily giggled. “Don’t hesitate to take contact if there is anything.

 

Yuno nodded, watching as his parental figure left. His Vice-Captain made a whole scene, after the Black Bulls appeared inside of their base unauthorized. Everyone knew it was because of his beef with Finral but no one wanted the short vice-captain to be up their ass too. So it was decided that Finral had to open the portals outside the base.

 

“Yuno, can I ask something?” Mimosa still stood there. Yuno knew something had been bothering the royal girl but he didn’t comment on it. 

 

“Yeah.”

“Why has Asta been on heat suppressant since the start? Everyone knows that it’s unhealthy to not wait a couple of months after your first heat.”

 

Yuno closed his eyes, thinking about the past. What a nice life Mimosa must have had, to think like that.

 

“What do you think Sister Lily is?” Yuno asked.

 

Mimosa tilted her head to the side. “At first I thought she was a beta by her smell and aura, but she seems really knowledgeable about an omega’s needs.”

 

“That is because she is an omega.” 

 

“Huh?” Mimosa widened her eyes. “Why would she hide that?”

 

“You know how people view an omega, especially an unmarked one.” Yuno clenched his fists, nail digging inside of his palms. “Many people see them as a property, and it won’t always matter if they are marked. We lived in a small town, with Father and Sister Lily who couldn’t protect us if powerful alphas came knocking at our door. Therefore, Asta’s true nature had to be hidden, for his safety.”

 

“But, what about his health?” Mimosa asked.

 

“Having heat is a privilege, Mimosa. Being able to think about your health before your safety is a privilege. And is not one Asta could enjoy before now.”

 


 

 

Yuno snapped his head towards the moving door, a sharp feeling of panic surged inside of him. For a split second, Yuno worried what would happen if he lost control.

 

“Y-Yuno?” 

 

There stood Asta, in his indoor clothes, looking like he came from battle but still smelling so good. “Can you come in?”

 

Yuno wanted to grab the shorter teen and throw him on his bed as he would do everything he had been imagining the past days.

 

Control.

 

“I don’t think it’s a good idea.” Yuno wanted to scream yes so bad, trying to keep eye contact instead of looking at his lips. “I’m an alpha.”

 

“You’re Yuno.” Asta snorted, walking out the room, not thinking of the consequences of his action. “And it’s starting to feel a bit lonely being inside your big room. I haven’t seen another human being for almost a whole day now.”

 

“Asta…” Yuno stood up from the floor. He could clearly see Asta not being in heat anymore, but his scent still smelled so good.

 

“I trust you, Yuno.” Asta said, before he grabbed the other boy and dragged him inside. “Stop being such a worrywart and lay down with me.”

 

Asta had found himself back to the bed, waiting for the other boy to join him.

 

“Come on, it’ll be just like we were kids.”

 

Except we aren't kids and I want to consu- Yuno tried to shake away the dark thoughts, before he took of his shoes, accessories and outside jacket. 

 

He settled onto bed, beside Asta. Before he could get comfortable, Asta shifted closer, curling towards him. He laid his head on the taller boy's chest, feeling the need to hear his heart. For a minute, Yuno stiffened, worrying what would happen if he lost control. The moving boy brought him out of his thoughts.

 

Yuno relaxed in his touch, his arm around Asta, his Asta. Soon, they found a position that felt natural, Yuno’s fingers playing with the other’s boy hair, Asta’s legs tangled with the other ones. 

 

The same position they would be in, after Yuno had been having a rut, and needed some comfort and human touch after some difficult days. Now it was finally his turn to give Asta comfort and protection. Maybe it was sick of him to say, but it felt nice being the person Asta could rely on now.

 

“This is the worst.” Asta mumbled. “I rather want to get my arms smashed again than go through this dumb heat again.”

 

“Hmhm…” Yuno hummed, moving his fingers down to his back, his fingers went underneath Asta’s shirt, as they started to trace lines on his back, hoping the touch will bring him some comfort. “It’s over now, you did great.”

 

Upon those words, Yuno felt dampness soak into his shirt. The boy beneath his hand started to break down, shoulder shaking as quiet sobs slipped free.

 

“I hate this… I hate it so much.” Asta sobbed, his body curled in on itself as he clung to Yuno, not caring enough to control his strength. He needed someone to hold on as he broke down. “I don’t want to go through this again.”

 

Yuno could only clench his jaw. It seemed Sister Lily had told Asta he couldn’t go on heat suppressant for a while. Once the first heat starts, it should go some time before someone starts using heat suppressant, unless they want to damage themselves too much. Asta was in a safe position now to finally have his heat without any worry.

 

“You can do it.” Yuno tried to reassure, not used to seeing his Asta so broken. “There is nothing you can’t do, except being the wizard king of course.”

 

“Hehe,” Of course, that seemed to stop Asta from crying. “We both know the title is mine.”

 

“Keep on crying, Shrimpsta.” 

 

“The best Alpha of the year goes to you.” Asta sarcastically said, wiping his tears.

 

“Shut up.”

 


 

 

“Well, then I’m off!” Asta waved.

After yesterday’s crying session, Asta went fast to sleep. He woke at an ungodly hour in the morning and went training at the Golden Dawn’s training ground. Some alpha approached him, telling Asta that he should join them in their room. The heat may be over, but his scent still lingered.

 

Of course, it ended up with the group of alphas getting their assed beaten up. Yuno had woken at the perfect time seeing Asta doing God’s work. And damn, he looked good.

 

Yuno high-fived him but Langris ruined the moment of course. Caused another scene saying that the Black Bull stayed too long and he should get punished. Captain Vangeance swopped in and said a couple of comforting words to his vice-captain. He gave an apologising look to Yuno, and Yuno knew his little sleepover was over.

 

Finral had been waiting outside their base, to pick Asta up.

 

“Don’t do anything stupid, you dork.” Yuno smirked, trying to ignore the hollow feeling inside of him that appeared.

 

Not comforting words someone should say to an omega who experienced his first heat at the age of sixteen. Finral thought. But of course, Asta was not any omega.

 

“Yeah yeah, I’ll miss you too, handsome jerk.” 

 


The next time Asta got in heat, Yuno wasn’t there.

 

Something Yuno had been dreading.

 

Mimosa told him heat usually happened once in a month, but since Asta had been on heat suppressant, the timing was different. It has been almost two months since Asta's first heat, and his whole squad has been on guard ever since. No one was allowed near their base, unless they wanted to face the Black Bulls’s wrath.

 

Not like anyone wanted to go there. Yuno thought. He was on his way to his room after another mission. His empty, cold room, where Yuno couldn’t ignore the hollow feeling inside of him.

 

Going from sharing a room with the kids in Hage and to have one alone, was a big difference. There were some nights he could ignore how lonely it felt, but after Asta leaving, it became clear how huge the room felt.

 

Yuno stopped in his tracks, smelling something familiar.  He breathed it in, the scent he had been missing for two months, the same scent that made him almost lose control.

 

Asta is here.

 

Turning around, Yuno followed the scent, using his magic to move around faster. At the front of the gate to the Golden Dawn, he saw his salvation.

 

“Asta!” Yuno ran to the shorter teen, who was leaning against Finral.

 

“Y-Yuno…” Asta breathed heavily, the same breathing patterns Yuno imagined in his dream, where he went down on the teen. “H-heat… help…”

 

The two words were enough for Yuno to grab the boy, lifting him up and dashing back to his room. He gently put the boy on his bed, not caring if Asta was wearing shoes and outside clothes. His safety was first.

 

Yuno glanced at him, from the marks and cuts, it looked like Asta was on a mission. And yet, Asta came to him, his Asta made sure to come to him in a vulnerable state. Oh, how blessed Yuno felt, and a small sense of pride. 

 

And here was Yuno, staring at the vulnerable teen who laid on the bed, thinking of all the positions they could do-

 

“No.” Yuno snapped out of his thoughts. He turned around and was about to leave, until he felt a hand on his cape.

 

“D-Don’t… Please don’t leave Yuno.” Asta pleaded, not realizing the situations they were in. “I don’t .. Don’t leave me alone.”

 

Something inside of Yuno broke. He didn’t want to let the teen suffer alone, but he would suffer even more in his presence. Asta thought so good of a taller teen, not realising all the dark thoughts Yuno had of him. 

 

Asta was so naive and carefree. 

 

Yuno removed his cape, throwing on the suffering boy. He stormed out of the room, ignoring the pleading and crying. Not knowing this would cause trouble later.

 

He collapsed at the wall once more, sliding down to the ground, trying to control his breathing. Yuno doesn't know how he would survive another week of hell.

 


 

 

Luckily, Mimosa had been made aware Asta was inside of Yuno’s room.

 

She came rushing, yelling - yeah actually yelling at Yuno, which was out of her character – that he should’ve said something sooner. Yuno didn’t really know how bad the heat could be, it seemed way worse than a rut.

 

Compared to Asta, Yuno was lucky to experience his rut when he was younger. Father had to just lock him inside of his own room, and he had been the only one going inside to give Yuno food and drinks. Before starting on heat suppressant himself, he remembered that he was just horny all the time.

 

Yuno felt the presence of a new mana appeared. 

 

Finral had opened a new portal, beside his room. Oh, he just knew Langris is going to cause a scene later.

 

Vanessa came out of the portal together with him, holding a basket of various things.

 

“Cavalry is here!” Vanssa winked, with so much energy that Yuno wondered what the Black Bulls members ate. “Take a break pretty boy, cuz you are going to have night duty.”

 

Yuno just wished Asta could get laid by someone by now.

 


 

 

After four horrible days of Asta suffering, the heat was finally over. And Yuno felt so drained from being on guard for days, releasing his pheromones and mana to keep away other alphas. That was a lie. He was drained of the desires he had been feeling, but unable to satisfy his needs. Especially when the one person he wanted, was across the door, all submissive and ready for an alph-

 

Anyway, Yuno thought it wouldn’t be as bad as last time, but oh, he was wrong.

 

Asta had gone crazy from his heat the other day. Yuno would not enter the room until Asta was done with his heat, but he had come running inside when he heard Mimosa screaming, and smelling a sharp and overwhelming scent hit his nose.

 

Asta had taken out his swords from the grimoire and started to hit himself. Screaming like he was a crazy person. Mimosa tried to hold the boy down, but naturally, he was stronger and threw her away. No one could hold the other boy, without using their magic.

 

Yuno tried to cool him down with his mana, which Asta accepted and sat down, enjoying the cold breeze. But it didn’t help for so long before Asta started to hit himself with his sword again.

 

“Heat isn’t a magical condition, you won’t be able to stop it.” Yuno commented, trying to think of anything else than how good Asta smelled. “You idiot.”

 

“I know that, you jerk!” Asta shouted, dropping his sword and screaming in frustration. “I just want to feel something else!”

 

Oh, I can help you. Yuno thought, observing the flushed boy’s face. Tears were streaming down from the frustration, lips looking swollen from the biting and the blush underneath his eyes only made the green color stand out even more.

 

Without realizing it, Yuno had let out his pheromones, and it seemed like Asta was reacting positively to it, his breathing easing. Mimosa on the other hand, stiffened. She shifted into a defensive stance,  her grimoire starting to glow.

 

Maybe, Yuno thought as he walked a bit closer to Asta, who stared at him in confusion and trust. Maybe this wouldn’t be bad.

 

Yuno stopped right in front of Asta, who was still sitting on the floor and looked up. Yuno was used to having to look down to meet the omega’s gaze, but it was different. Completely different. It was something about Asta looking like that. Looking like he was ready to get fu-

 

“Oh no, get out of here brat.” Strong hands grabbed Yuno’s collar, and threw him out of his room.

 

Yuno barely had time to register what happened before he hit the ground. He blinked, expecting to see the ceiling but instead saw the open blue sky.

 

For the first time in a long while, heat rushed to his face. Yuno hasn't felt embarrassed like this for a while. Of all people who had to stop him, it had to the Yami Sukehiro of the fucking Black Bulls. 

 

“Shit.” Yuno muttered, stubbornly refusing to acknowledge the blush burning across his face. 

 

But all of that is over now.

 

Finally, Yuno was back in bed beside Asta again, the shorter teen tucked closed against him. He needed comfort again after the heat. Yuno didn’t expect anything in return for protecting his friend. But still, he couldn’t deny that this felt rewarding. And he was glad that Asta didn’t mention what had happened the day before.

 

“This is nice.” Asta murmured sleepily, relaxing under the touch of Yuno. “You’re way better at this than Noelle and Luck.”

 

Yuno huffed, feeling annoyed at the mention of someone’s name, but continued with the slow, reassuring motion.

 

Way to ruin the mood, Stupidsta.

 


 

Ok, Yuno lied.

 

He didn’t want Asta to get laid by someone, but by him.

 

Both of them were relaxing in the hot spring, together with Yami and the Crimson Lions, after an intense training session. Yami had gotten annoyed at Yuno. Yuno didn’t really get it, he wasn’t interested in peeking at the women’s side without their consent, but apparently Yami found that annoying.

 

Yuno was drying himself with his magic, along with Yami and some of the other Crimson Lion members, getting ready to get dressed and leave. 

 

“Hey, join my squad! You can be useful as my personal dryer.” Yami laughed, wanting to get out the teen’s nerves.

 

“No thank you.” 

 

“C’mon, there is no more honorable job than that.”

 

“Tch.” Yuno scoffed, how could Asta put up with him.

 

Yuno finished putting on his clothes, moving to get his grimoire.

 

“Well, would ya look at that.” Yami exhaled smoke. “The lion cub is trying to mate with the brat.”

 

Yuno stared at the man in confusion, following his gaze to an ungodly sight.

 

He saw Leopold’s arms wrapped around Asta, as he kissed the grey haired boy. What made it worse, Asta was accepting the alpha’s action. 

 

“Asta… you smell so good.” Leo moaned, wanting more of him. Yuno realized Asta was in heat again.

 

Yuno didn’t know what to feel. 

 

Anger? 

 

Heartbreak? 

 

Rage? 

 

Betrayaler?

 

Everything twisted together in his chest, too sharp and heavy to ignore, but he had to ignore it. He had to get his Asta away from the red haired boy. Before Yuno could move an inch, he felt strong arms his chest, which limited his movement.

 

“What are you doing?!” Yuno didn’t need to look behind to see it was Yami holding him. 

 

“This is the first time I’m seeing Asta enjoy being in heat. Don’t be a cockblocker.” Yami laughed. 

 

The words didn't register in his brain, too focusing watch as Leopold’s hand disappeared down in the water, and Asta's face flushed even more, making noises that were only meant for Yuno’s ears. To make the matter even worse, Asta was asking for more!

 

“You want to save him? Push your limits then, kid..”

 

The rage inside of Yuno, should’ve made him see red and black out, but instead he saw green. A green light emitted from the teen who wielded the Spirit of the Wind.

 

Three seconds later, Asta was in Yuno’s arms, exactly where he was supposed to be.

 

“Ah – Yuno!” Asta shouted in surprise, his arms naturally holding the taller teen.

 

Yuno tightened his hold, afraid if the boy left his arm, that he would disappear again. His heart was pounding, from anger? From fear?

 

For the first time, Yuno wished he had a different attribute. Fire would have been perfect, so he could burn Leopold to ashes and erase his fingerprints from Asta’s body. 

 

“He is mine!” Yuno roared at the royal boy, not knowing if it was a claim or a desperate declaration. “Remember that.”

 

With that, the two teens disappeared in the wind.

 




Yuno barged into his own room, throwing the omega in heat on his bed, rough and no care. But Asta didn’t protest, not like he cared.

 

Asta looked up, eyes widened, with a small feeling of hope blossoming. 

 

“He is mine.” The words echoed in his brain, warm and reassuring filling inside of him.

 

After his last heat, Asta thought Yuno wasn’t interested in him. He realized the taller then must only view him as a friend. Therefore, when Leo touched him, Asta didn’t think it would cause trouble. Not like the omega wanted to make trouble, but this situation felt satisfying so far.

 

“Yuno?” Normally, during his heat, Asta struggled to even lift a finger. But today felt different. Adrenaline in his system gave him the boost he needed.

 

Asta raised his trembling hand toward the glowing boy, the warm feelings inside of him getting stronger.

 

SLAP

 

Asta stared at his hand that had been slapped away, rejected. Confused washed over him, he looked at the taller teen again, this time truly seeing his face. The shift is instant and devastating.

 

The omega did not like what he saw inside of Yuno’s eyes. It was a familiar look, the same ones the members of the Eye of Midnight Sun have given him before. A sinking feeling settled in Asta’s stomach.

 

“What the fuck is wrong with you?” Yuno snarled. “Are you going to throw yourself at the first alpha that gives you attention? You’re better than this!”

 

Oh.

 

Oh.

 

How dumb could Asta be? 

 


 

 

The words left Yuno’s lips, faster than he could think. And honestly, at this moment, Yuno did not care. He wanted Asta to feel the same pain he was feeling. The look in Asta’s eyes, the look of pain and betrayal should satisfy Yuno’s anger… right?

 

“Get the fuck out!” Asta screamed, baring his teeth in anger.

 

Yuno swore he saw his right eye glow red, before it flickered back the green eyes he loved so much. The same green eyes that had been sharing an intimate moment with someone else.

 

“Fine!” Yuno shouted, turning around, not noticing the other boy grabbed something at the nightstand. 

 

“Fine!” Asta shouted back.

 

thud

 

A sudden gush of wind rushed past Yuno, as he stared at the hole on the wall, right beside the door. He looked down, to see the material Asta had thrown. 

 

Yuno opened the door, taking a single step outside. He paused, then glanced back over his shoulder. Making eye contact with the sweating boy who was oblivious in pain. He took another step outside. He said his last word before closing the door hard, his last word hanging heavy in the air.

 

“Pathetic.”

 


 

 

That night, two teens fell asleep with a broken heart. One feeling unworthy and dirty while the other feeling like he was never enough and unloved.

 


 

 

On day three of the heat, Yami had dropped by to switch places with Yuno.

 

“Y’know, if you’re not going to do anything, ya might as well let the fire boy smash him.”

 

The first thing Yuno would do when he becomes the wizard king, is to murder Yami Sukehiro.

 


 

 

The heat was over, Yuno knew it. 

 

Asta knew that Yuno knew, but he still didn’t enter the room. He kept staying outside, guarding the room. Somewhere inside, Asta did feel hopeful knowing that the other boy didn’t leave. Maybe Asta had a chance to talk things through. 

 

Asta stood up, he opened the door, seeing the alpha on the ground, face buried against his knees. Before Asta could say something, the other boy beat him to it.

 

“If your heat is over, leave.” Voice cold, no feelings behind it. Yuno’s face is still hiding.

 

“C’mon Yuno, come inside and cuddle with me.”

 

Tempting, it was so tempting to touch Asta, but all he could think of is a certain royal boy who touched his Asta, and his Asta enjoying someone else’s touch.

 

“As if I want to touch you.” 

 

Silence fell in the hallway. Yuno just wanted to get sucked by the floor, disappear completely. Ashamed of the words he spoke. Asta would never respect him now.

 

“You’re such a jerk, but at least cuddle with me while you’re being so mean.”

 

Yuno’s head snapped up, stared at the boy in awe. Asta, his Asta, stood in front of him, with a smile on his face. Only this idiot could take an insult without feeling bothered.

 

“Do you have no self-respect?”

 

“Says the one sitting outside my room, even if he is ‘angry’.” Asta fired back. “Honestly, I don’t understand why you're even that mad. It wasn’t like Leo forced himself on me.” Yuno could see blush appearing on the shorter teen’s face. “I kind of enjoyed it.”

 

“Tch.” Yuno felt anger rising instead of him again, murder would be committed. “Then run back to him.

 

“Shut up and join me in bed. It's so cold.” Asta grinned at the teen still sitting on the ground. “I need a big and strong alpha warming my tiny, weak omega body.”

 

Yuno rolled his eyes, before grabbing the arm Asta had extended out for him.

 

The two teens settled in bed, curling up to each other. Both touching each other like the other person would disappear. Yuno burrowed his face in the neck, taking in Asta’s smell, trying to memorise it, afraid he wouldn’t get a chance to ever lay down with him like this.

 

“You know, after the makeout session with Leo, I realised something.”

 

Read the room, Yuno wanted to shout, feeling like the mood was ruined.

 

“What?” Yuno asked, maybe he realised how good of alpha Leo would be for Asta, maybe he would let the other boy mark him. If Asta felt the arms around his body tightened, he didn’t comment on it.

 

“The heat isn’t that bad, if I share it with someone.” 

 

Yuno froze, he felt his heart stop for a moment, holding his breath, waiting for the rest of the words to leave the omega’s mouth.

 

“His touch felt so nice, it was way effective to cool down the uncomfortable feelings my heat caused.” Asta let out a small laugh, a fucking laugh? Why is Asta laughing while thinking of Leopold?

 

“So I thought, maybe I should try and mate with someone. But it won’t be soon before I can start on the heat suppressant again.” Asta babbled, not noticing the other boy was shaking before he heard a noise.

 

Is Yuno… crying? Asta blinked, surprised to see tears stream down, a sight he hadn't seen since they were kids.

 

“Yuno?” 

 

Yuno didn’t react to his name, only burrowing his face deeper in Asta’s chest, body shaking from frustration and pain, holding Asta even tighter.

 

“W-Why…” Yuno's voice was starting to break down from all the feelings he held. “Why can’t I be worthy of you?”

 

Feelings of frustration, heartbreak, unworthy and unwanted had been settled in Yuno’s bones, the feelings he tried to hide had finally come out.

 

“I just- Just let me prove myself to you.” Yuno’s head snapped up, tearful amber eyes meeting shocked green eyes. “I’ll be the wizard king and accomplish our dream, so please, let me prove myself to you. Let me be worthy of your love”

 

Asta stared in shock, not knowing what to say for the first time. The two teens kept their intense eyecontacting, Yuno feeling warm hands on his cheek.

 

Instead of words, it was natural responding to Yuno's question with actions.

 

What better ways to respond to a love confession, other than a kiss?

 

The two teens were used to being rough, used to get blown or thrown away, they were used to the pain. Maybe that is why Asta kissed Yuno with so much care and love, and Yuno kissed him back gently, afraid to break the boy if he pressed harder.

 

The kiss broke after what felt like hours.

 

“I don’t really understand what you mean by worthy of my love, when I feel like the unworthy one.” Asta whispered, staring at the other boy with so much feelings. A familiar feeling of heat coming back.

 

“You’re worthy Asta, you’re the only one I want.” Yuno whispered back, kissing him on the cheek, his whole body relaxing as it finally got the touch it craved, the love he was seeking. “I love you.”

 

“L-Love me?” Asta stuttered, feeling a bit confused and overwhelmed with all the feelings. 

 

“Yeah, I love you Asta.” Yuno spoke to the words so low, the look in his eyes was pleading, pleading as if he was afraid of losing Asta again. “It’s fine if you don’t, I love you enough for both of us.”

 

Asta felt a skip in his heart, realising the feeling Yuno referred to. It was the feeling Asta has always had for Yuno, a different type of love from the ones he had for his friends and family. 

 

“I would give up my dreams for you, Yuno.” Asta blurred out. 

 

Yuno couldn’t ask for a better way to say I love you.

Notes:

I needed to finish my other story, but couldn’t get out of my writing block.

I actually wanted to drag the angst, but felt it being out of character for Asta to not try and resolve the issues then and there. They both feel out of character, especially the last part but it was fun writing this!

Since this is my first alphaxomega fic, i kind of forgot using elements from this au more but oh well. I wrote this for hours and now ready to sleep. Maybe one day I'll fix up grammar mistakes and write more of this AU.

Noelle was actually suppose to make more appearance but i guess it felt natural writing more of Mimosa. And yes, I Made Yami a dick intentionally. After Asta’s first heat, everyone it Black Bull knew how much he was pining for Yuno. So this is Yami’s way of supporting them

Please tell me what you think! Hopefully I’ll write more YxA stories in the future !
