My Omega Mafia Boss

Summary:

Oikawa is the Mafia Boss, renowned all around the field for his ruthlessness and beauty. Many have approached him, men and women alike, but he turned down every single one of them as he has been pining over his childhood friend, Iwaizumi from the moment he found out what the word “like” is.

However, now he must navigate through his feelings as he faces against their rival gang to sabotage their threatening plot.

Notes:

This work is my gift to my wonderful beta reader, blue_tree96, for her wonderful job proofreading my story “For You, I’d do Anything”

Thank you so much! Enjoy! 🥰

Work Text:

“Argh! That darned Ushiwaka!” Oikawa screamed as he pushed through the front doors of his mansion followed by a bored Kunimi and a worried Kindaichi. The people in the mansion didn’t even bat an eye at the boisterous way that their young master entered the abode, already used to the other’s overly dramatic antics.

 

“Oikawa-bocchan please be gentle. We shouldn’t waste money to buy the fourth set of front doors for this month,” Kindaichi commented .

 

Oikawa spun around and stared at his underling with wide raged eyes.

 

“Do you think I care?!”  

 

Kindaichi flinched then immediately bowed a perfect right angle at being yelled at by his boss.  

 

“No, bocchan! I deeply apologize for my unnecessary comment,” he said.

 

Kunimi rolled his eyes behind him. “You should already know when to shut your mouth by now.”

 

Amidst his underlings’ chatter, Oikawa stormed off to the kitchen where he proceeded to devour the lone slice of vanilla cream cake he saw there. While in the middle of stabbing his fork into the innocent slice, he heard someone clear his throat from behind him.

 

“Why are you eating my cake?” Iwaizumi asked gruffly from behind him.

 

Without looking behind him, Oikawa scoffed and continued eating.  

 

“You don’t eat vanilla cake. I’m the only one who eats vanilla cake here, so it’s obviously for me.”

 

“What if I wanted to try it for once?” Iwaizumi asked.

 

Oikawa stopped eating and finally faced his personal bodyguard and right-hand man, who has been with him since they were children.

 

“If you want to try it so bad, then come taste it from my lips,” he said as he puckered his lips stained with a little bit of vanilla cream on the corner.

 

He only earned a hard smack on the back of his head.

 

“Don’t do stupid shit like that,” Iwaizumi said with an annoyed expression, yet the tips of his ears were tinged slightly red. The young master only pouted and whimpered at his childhood friend .

 

“Anyway, you’re annoyed. Is it Ushiwaka again?” Iwaizumi asked, sitting down on the stool beside his young master.

 

Oh , you bet it’s because of him! You won’t believe what he did this time!” Oikawa said as he again stabbed the innocent cake out of fury.

 

“What is it this time?” Iwaizumi asked. His expression may look bored , but he is slightly amused by the situation. Seeing Oikawa all riled up was too funny, though he is getting a bit fed up with the constant mention of the head of their rival group’s name.

 

“He invited me to be part of his gang, AGAIN! Does he not have eyes to see that I have a gang of MY OWN that I am part of? What part of ‘NO’ does he not understand?! It’s just two letters with one meaning! I— uugghhh!” The young master groaned as he angrily stabbed the poor cake slice once again.

 

“Calm down, I have new intel on his troupe and I’m sure you won’t like it, so I need you to calm down first before you get angry again,” Iwaizumi said.

 

Oikawa looked at him with fury.

 

“You think saying all of that would make me calm?!” He said, enraged.

 

“No, but you never did listen to me, so I’ll just do the opposite of what I really want you to do,” Iwaizumi responded.

 

Oikawa could do nothing but sigh as he ran a hand through his hair, trying desperately to calm himself down.

 

“See? Me making you angrier just makes you calm down,” Iwaizumi smirked.

 

The other just rolled his eyes. “Just get to the point.”

 

Iwaizumi cleared his throat as he turned on the tablet that be brought.  

 

So , we found out that Ushijima’s gang is in possession of a dangerous drug that rival’s the one we’re producing. If this goes out to the black market, it has the potential to undermine ours, causing severe losses to our profits. Plus, they said it’s almost complete, and once it finally is, nothing is stopping Ushijima from realising it out into the world,” Iwaizumi briefly reported.

 

“So… basically we have to stop it from being completed and prevent Ushijima from realising it,” Oikawa surmised.

 

“Exactly . ” Iwaizumi said, then turned the tablet on once again. “Also, Ushijima’s hosting a party soon, probably to lure in potential investors for the drug as well as customers .

 

Oikawa glared at his most trusted man.  

 

“You’re not implying what I think you’re implying, are you?”

 

Iwaizumi smirked once again. “What do you think I’m implying?”  

 

“That we infiltrate this party and get rid of the drug and its traces while the owner is away . ” Oikawa said.

 

“Those are your words not mine, and I think that’s a great idea,” H is right-hand man grinned.

 

“Why you —“Oikawa paused. “I’ll have you dress up and act like a potential investor . H e grinned.

 

“No way, that will take way too much time to produce a believable background for me, plus would he really trust someone he will just meet on that day?”

 

Oikawa huffed. He hates it when Iwaizumi has a point.

 

“I say, we make use of what he really wants. We already have it,” Iwaizumi started.

 

“And what would that be? Huh?” Oikawa challenged him with his arms crossed.

 

Iwaizumi merely maintained eye contact with his young master, letting Oikawa slowly realize what he meant.

 

“No way… NO FUCKING WAY!” Oikawa said, enraged once again.

 

“I knew you’d be mad again, but this is really the most viable option . ” Iwaizumi said.

 

“And what makes you think he’ll believe me if I ever lie and said that I will leave my gang and join his?! Of course , he’ll doubt me! I’ve been refusing him for years; I can’t just do a complete 180 and suddenly agree with no reason!” Oikawa complained.

 

“We’ll give him a reason. I’m working on that reason right now .

 

Oikawa paused. “You had this all planned out from that start, didn’t you?”

 

Iwaizumi said nothing and merely cleaned up his young master’s mess in the kitchen.

 

“You’re so cunning, you know that?”  

 

Iwaizumi faced him with a small grin. “I wouldn’t have survived as your right-hand man if I wasn’t, bocchan.”

 

 

 

~*~

 

 

 

“Run this by me again real ly quick,” Oikawa said as he rubbed his temples. He was getting a headache from all that’s been happening lately, and Iwaizumi’s plan for the “reason” is adding to his headaches.

 

“So, you want me to pretend that I fell in love with Ushijima, hard enough that it convinced me to leave my gang and join his?” Oikawa reiterated.

 

“Yes,” Iwaizumi simply stated.

 

“ARE YOU INSANE?!” Oikawa screamed. “I’d rather gouge out my eyes than give that shithead a lovestruck look! Ugh, just the thought of it makes me shiver in disgust!”  

 

“This is for the betterment of the gang, bocchan. Deal with it,” Iwaizumi said as he went about his young master’s room and gathered his things for the day.

 

Oikawa flopped down unto his bed and sighed as he raised an arm to cover his eyes from the light. “If I’m gonna be in love with someone, I’d rather it be you…” he grumbled.

 

“What was that?” Iwaizumi asked as he looked behind his shoulder.

 

“Nothing, you knucklehead!” Oikawa exclaimed.

 

His right-hand man ignored him and instead presented the clothes he picked for Oikawa to wear to Ushijima’s party in a few hours.

 

“Right, so the plan is you’ll pretend to be jealous during the party when you see Ushijima flirting with other omegas. Then you’ll talk to him, confess your feelings, then distract him for even just half an hour. Then the rest of the gang will infiltrate his lab and destroy the drug along with all the documents . ” Iwaizumi said as he finished grabbing all the necessary shoes and accessories to match the outfit as well.

 

“And where will you be during this whole fiasco?” Oikawa asked as he eyed the outfit for him. He gotta admit, Iwaizumi has a great fashion sense. Who knew?

 

“Guarding you, of course,” Iwaizumi said with such a loyal and sincere gaze, it made Oikawa’s heart skip a beat.

 

The young master had to look away, the tips of his ears blushing red. “Right, cause that’s your job, right…”

 

Iwaizumi turned around and started looking for the perfect perfume to match the outfit. “Even if it wasn’t my job, I can’t stand not having you in my sight. I can’t leave you alone no matter what.”

 

At that, Oikawa blushed even harder. His cheeks now matching the red shade of his ears.  

 

After his right-hand man had everything prepared for Oikawa, he stood by the door and gave a slight bow.

 

“I’ll leave you to get dressed then. Break a leg tonight , Oikawa, both figuratively and literally,” Iwaizumi smiled before closing the doors as he left.

 

“Smiling like that is unfair, Iwa-chan…” Oikawa muttered as he stared longingly at the door.

 

 

 

~*~

 

 

 

At the party, Oikawa was turning heads as soon as he walked in. His turquoise suit matched with white dress shoes and gold accessories made him the highlight of today’s event. No one could outshine him, even if they tried. Beside him is his right-hand man, Iwaizumi, dressed in all black, aside from the turquoise lining of his black jacket’s lapel. Oikawa honestly loved that small splash of turquoise on his subordinate’s suit. It seems like the suit was made entirely for Iwaizumi, yet the turquoise touch made it seem like he was a pair with Oikawa. His omega instincts loved it.

 

What he didn’t like however, are the gazes from the nearby omega’s eyeing Iwaizumi up and down, like hungry predators ready to pounce on their prey.

 

Oikawa stood slightly behind Iwaizumi, and glared at all the omegas who looked their way. None could stand being subjected to his fiery gaze.

 

“Oikawa look, there’s Ushijima. Let the show begin,” Iwaizumi whispered before he began distancing himself from Oikawa to allow the other more freedom to move and commence the plan.

 

Oikawa sighed exasperatedly before he too began moving closer and closer towards Ushijima. As he got closer however, he began to get nauseous at the thought of being lovey dovey with his enemy.  

 

“I can’t do this with a straight mind. Where’s the punch?”  

 

He looked around and found the drinks table. He grabbed a cup and drank it all in one go.

 

He wasn’t a lightweight, so he needs more if he’s gonna make himself a bit tipsy for the plan.

 

He grabbed another cup, then another, and on his fourth cup, he finally felt the beginning of the alcohol entering his system.

 

“Okay, this is much better,” He said before turning around to face Ushijima once again.

 

However, his eyes were much too focused on the pair behind Ushijima. There stood Iwaizumi, happily chatting away with a short omega.

 

Oikawa felt beyond irritated. He was there drinking so hard to get himself prepared for the torture he was gonna face for their plan, and there stood his partner talking so cheerfully with another omega?  

 

He could feel a vein popping on his forehead from his annoyance.

 

Iwaizumi noticed him at that moment. Oikawa was about to feel relieved, thinking that maybe Iwaizumi will go back to his side now, but instead, Iwaizumi quietly motioned for him to move towards Ushijima.

 

Oikawa was beyond livid at this point. He stomped towards Ushijima, grabbed the man’s collar and dragged him down for a kiss.  

 

“I’m fucking in love with you, now come with me!” He said before he dragged Ushijima away from the party and into the garden outside the venue.

 

Iwaizumi better be happy that he’s doing his part of the plan! He wants Ushijima distracted. Oh, he’ll distract him alright!

 

 

 

~*~

 

 

 

Iwaizumi saw the commotion that Oikawa caused up until he dragged the rival gang leader away, probably to the garden based on the direction they’re going. He knew it was his plan to have Oikawa pretend to be in love with the other to distract him, but watching the omega kiss another man made something inside of him boil with anger.

 

“A kiss wasn’t part of the plan…” he grumbled.

 

He scrunched his brows and gripped his chest, trying to calm his raging heart.  

 

After a few deep breaths, he shook his head and made eye contact with Kindaichi.  

 

“Move, and make it quick,” he mouthed.

 

Kindaichi nodded before leaving. The rest of the Seijoh gang, who were currently in hiding around the vicinity, also moved when they got the signal.

 

Iwaizumi knew he should be following close behind as well to monitor the plan in their leader’s stead, but somehow, he found himself walking towards the balcony that oversees the garden down below. He placed himself inconspicuously in the corner and glanced down.

 

Below, he saw Oikawa completely in character, tho a bit red in the face. He probably drank a bit to handle the job.  

 

The right-hand man knew of his leader’s utter disgust and hatred for their rival gang’s leader. He know s this and truly understands it, but at that moment, he can’t help but feel jealous at the scene before him—Oikawa’s body pressed against Ushijima’s as he looked at him with lidded eyes. From his angle, he can’t see Ushijima’s face, but him putting his hand on Oikawa’s cheek and caressing it almost made him jump down and beat the living hell out of the other alpha.

 

He was gripping the balcony rails tightly when Oikawa’s eyes suddenly shifted towards him. The omega raised a brow then gestured with his eyes to move on with the plan.

 

Iwaizumi took a deep breath.  

 

“Right… the plan…” he whispered as he combed back his hair. He nodded to his leader.  

 

He has no time to be jealous. He doesn’t even have a right to be jealous. Oikawa wasn’t his, but he so badly wanted him to be though.

 

All he wanted was for his leader to distract the other a bit, but Oikawa had to go above and beyond. He should’ve expected that, but then again, Oikawa is unpredictable. Even he doesn’t fully know what to expect of the other.

 

He turned on the skin tone earpiece he had on and said, “Status and coordinates. Asap.”

 

The sooner they finish the task, the faster he can get Oikawa as far away from Ushijima.  

 

 

 

~*~

 

 

 

“Oikawa… That was a surprise,” Ushijima said as soon as they got to the garden.

 

Well , uhh… with all of those omega around you tonight… I guess I couldn’t help but… f-feel…” Oikawa stuttered. Just the mere thought of confessing his love to Ushiwaka made him want to puke his guts out.

 

“…jealous?” Ushijima continued for him as he tilted Oikawa’s chin to look make the other look at him.

 

Oikawa’s smile froze and he looked to the side. “Y-yeah… I got jealous…”  

 

Ushijima chuckled before he wrapped his other arm around Oikawa’s waist.  

 

“You don’t have to be so nervous,” T he rival gang leader whispered by his ear.

 

A shiver went up Oikawa’s spine from the tone of Ushijima’s voice.

 

“I-I’m not…” Oikawa said, trying to push the suddenly close alpha away a bit.

 

“Are you nervous because of our position right now or are you nervous that I’ll find out that you’re just pretending to be in love with me?”

 

The omega’s eyes widened at that. Yes, he wasn’t the best actor, but he didn’t think he was that obvious.

 

“You hate me. I know that very well. I can see it in your eyes every time I see you and that was one of the reasons why you intrigued me from the start,” Ushijima said as he began to circle around Oikawa. “You weren’t like the other omegas I met that were all willing to throw themselves at me the moment I merely look at them. You were different, and I liked that about you.”

 

Then, he harshly grabbed Oikawa’s face. A frown was etched on to Ushijima’s lips as he glared at the omega. “But tonight, you looked like every other omega in that party. You disappointed me.”

 

Oikawa had enough of pretending and slapped Ushijima’s hand away. Rage could clearly be seen in his eyes.

 

“I’m done pretending and I don’t care if I disappoint you or not. I want nothing more than to never see your annoying ass ever again.” Oikawa spat.

 

This in turn made Ushijima smirk, looking pleased.

 

“This, this is exactly why I want you.”

 

“You’ll never have me!” Oikawa exclaimed. However, he suddenly fell to his knees when an inexplicably hot sensation coursed through his veins. This feeling, it’s familiar.

 

“What… what did you do?” Oikawa groaned; pain evident in his voice.

 

“This is a gang party, obviously there will be something in the drinks, right?” Ushijima said as he stepped closer towards the whimpering omega.

 

“You lowly bastard... ! ” Oikawa screamed.

 

Just before Ushijima was about to grab Oikawa, a figure suddenly appeared between them, landing from the balcony above.

 

Iwaizumi now stood between Oikawa and Ushijima, shielding his omega bo c chan who was currently under the influence of a pseudo heat from their enemy. He growled as his eyes turned a rich shade of gold.

 

“Don’t you dare touch him!” He bellowed.

 

Ushijima, not backing down from the other alpha, also turned his pupils yellow and replied, “Who are you to demand such things of me?”

 

Oikawa stood up, although shakily, and grabbed on to Iwaizumi’s shoulder. He scented him right at the juncture of his neck as he glared at Ushijima.

 

“He’s my mate, now stop bothering us.”

 

Ushijima’s eyes narrowed.

 

“I don’t see a—“ He was interrupted when a loud explosion came from the opposite end of the mansion, right where the laboratory was . He looked back at the two of them, silent rage clearly seen in his golden orbs. “ So , this was your plan all along… I’ll make you pay for this!”

 

Ushijima tried to grab Oikawa, but Iwaizumi was quick to react. He blocked Ushijima’s hand and elbowed him in the guts.

 

The other groaned from the pain, but he was quick to recover and gave Iwaizumi an uppercut, grazing the corner of his lips as he tried to avoid it from such a close range.

 

Iwaizumi stumbled back a bit from the impact and spat out blood, probably from the cut he got from the other’s punch. Never the one to back down, Iwaizumi lunged at Ushijima again, using his speed and agility to get close to the other alpha. Ushijima anticipated his moves and tripped him from below. Just before Iwaizumi could fall to the ground, he pushed himself back up , kicking Ushijima’s chin from below during the process. The taller alpha stumbled back and held his quickly reddening jaw.

 

I can see why Oikawa keeps you,” Ushijima taunted with a glare.

 

“Keep his name out of your filthy mouth,” Iwaizumi growled.

 

You’re useful, and your loyalty outweighs everything. Just like a dog, running to protect its owner when they’re weak a nd vulnerable,” the taller alpha continued.

 

At this, Iwaizumi snickered. “I wouldn’t underestimate him if I were you . As you said, he’s not like any of the other omegas.”

 

“Whether he’s like the others or not, an omega will always be wea—“

 

Just before Ushijima could finish his sentence , he was swept off of his feet from behind. When he looked up, he saw Oikawa glaring down at him from above before he uncapped something from the bottom of his heel and quickly stepped on Ushijima’s biceps.

 

The alpha groaned in pain from being punctured by what seems to be a needle coming from the heel of Oikawa’s shoe.

 

“What did you do?!” Ushijima demanded.

 

“I’m a gang leader, obviously there will be something in my clothes, right?” Oikawa smugly retorted. “Never underestimate a fellow gang leader, Ushiwaka. You’re not the only one who knows how to play dirty.”

 

Then, he looked back towards Iwaizumi.“Iwa-chan let’s go! That should stop him for a while .

 

Oikawa grabbed Iwaizumi by the arm, but his right-hand man noticed the slight tremble his grip had. Without a word, Iwaizumi picked up Oikawa bridal-style and began escaping from the party. Everyone was in chaos, so it was easy to escape without being noticed.

 

From the distance, they can see a black car speeding towards them. Kunimi rolled down the car’s window and yelled, “Hop i n!”

 

The two got in without hesitation, and Kunimi drove the vehicle as far away from the commotion as possible.

 

From the passenger seat, Kindaichi sat, a little red in the face from the pheromones his bocchan was producing.

 

“Oikawa-bocchan… are you okay?” He asked, still concerned for his master’s well-being.

 

“I’m fine…” Oikawa said, trying to sound strong for his younger subordinate.

 

Iwaizumi noticed the younger’s dilemma and tried masking Oikawa’s pheromones with his own. “He’ll be fine Kindaichi, status report.”

 

Kindaichi, now able to breathe a little better, straightened up and began recalling the results of their plan.

 

“The plan was a success, sir! The drug was found and destroyed as well as everything related to it in the lab. Kunimi checked their system for possible back up files and destroyed those as well. The others are also safe and on their way back to our base.”

 

“Good job, now take it easy and take us all home.” Oikawa ordered them from the back.

 

“Yes, bocchan!” they all answered in unison.

 

 

 

~*~

 

 

 

That night, in Oikawa’s bedroom, Iwaizumi was busy tending to their still weakened master. He was frowning as he made tea at the bedside for Oikawa to drink.

 

Oikawa chuckled when he saw his expression.

 

“Are you worried that much? It’s just a pseudo heat, the doctor said I’ll be fine after the medicine he gave me. I just need to sleep it off,” Oikawa said.

 

“You’ve never been drugged before . ” Iwaizumi replied.

 

“Yeah, and who’s fault do you think that is? A gang leader who has never been drugged before, that sounds absurd, right? Cause you kept me so well pampered and protected that I’ve never experienced being drugged or poisoned or anything of the sort. You were too excellent at being my bodyguard . ” Oikawa said with a small huff of amusement.

 

“Apparently not that excellent if you’re in this state right now . ” Iwaizumi said as he motioned for Oikawa to sit up and drink the tea. Oikawa obliged and took a quick sip, relief washing through him as the warm tea soothed him.

 

He stared at the teacup and said, “Don’t be so hard on yourself.”

 

Iwaizumi sat on the bed beside him and sighed. “I though t of that plan and made you go through it alone. I should’ve been keener , maybe you wouldn’t have had to be in this state.”

 

Oikawa heard enough of Iwaizumi’s self-depreciating rambles. He placed the teacup down and cupped the other’s cheek. Without a second thought, he kissed Iwaizumi softly, making him know how he felt through that intimate contact.

 

The alpha was stunned at first, before he reciprocated the kiss with a hunger he never felt before, all depressing thoughts leaving his mind in an instant. As much as Oikawa wanted their heated moment to continue, they had to part for air.  

 

Oikawa parted their lips and bumped their foreheads together as he stared at Iwaizumi’s eyes.  

 

“Don’t say such mean things about my mate, okay?” He spok e .

 

Iwaizumi’s brows furrowed in confusion. “You keep saying that…”

 

“Because it’s true,” Oikawa said, pecking his lips one more time. “I want you as my mate… only if you want me back too?”

 

Iwaizumi lunged at Oikawa, capturing his lips in a searing kiss, much more passionate than the one they had before. He sucked the omega’s bottom lip, nipped it, and kissed it until it was almost bruised. Oikawa was left as a breathless mess once Iwaizumi was done with him.

 

“You don’t know how long I’ve been wanting to be your mate too…” Iwaizumi admitted.

 

Oikawa chuckled as he wrapped his arms around the alpha’s neck. “You should’ve said something.”

 

“Is the vanilla cake and 24/7 protection not enough?” Iwaizumi grinned.

 

“That was your job . ” Oikawa replied as he rolled his eyes.

 

“Who said I did all those things becau se it was my job?” Iwaizumi said, a hand caressing the omega’s now blushing cheeks.

 

“God I love you…” Oikawa whispered, heart beating a mile a minute at that moment.

 

“I love you too,” Iwaizumi said, as he gave Oikawa another kiss, this time softer and sweeter than the last. “And please for the love of god, let me be the only one you’ll ever kiss from now on.”

 

Oikawa laughed at his now boyfriend’s jealousy. “I wouldn’t want it any other way!” He said before kissing the pout off his lover’s lips.
