Bruised Knuckles and Stupid Heats

Summary:

Luffy presented as an Omega and refused to wear scent patches and refused to learn how to control his pheromones because he doesn't see any of this as a big deal. Who gives a shit about secondary genders and scents? Everyone starts acting differently around him, especially a certain someone who always ignores and rejects being friends with Luffy. Why has Trafalgar Law been paying more attention to Luffy?

Notes:

Hey guys! This is my very first One-Piece fanfic! I've been obsessed with Omega Luffy. So, enjoy!

(See the end of the work for more notes.)

Chapter 1: One

Chapter Text

Luffy sighs loudly as he flops onto the couch, his arms crossed over his chest, an annoyed expression on his face as he glares at his two brothers, who stare back, scolding him, like they always do. "We mean it, Luffy," Sabo says, his hands on his hips. "You will not be going to school unless you wear them," Sabo adds.

"No," Luffy says. "I don't want to."

Ace scoffed. "I don't care what you want or don't want. Luffy. You're wearing them!"

"Nope," Luffy says, turning his head to the right.

"Luffy, it's just for the first 3 months, okay?" Sabo says, his voice laced with pleading. "It won't be that bad."

"I don't understand why I have to wear them. Who cares about everyone finding out I'm an Omega?" Luffy says.

"Luffy, it's not about being an Omega. Your pheromones are unstable right now, and scent patches will help, but only when you go to school." Sabo says. "At home, you can just let your pheromones out as much as you want."

"Who cares that my scent is wild and unstable?" Luffy asked, rolling his eyes. He was already done with the morning.

"Everyone at school." Ace answers. "Look, I was as stubborn as you when I first presented as an Omega. I refused to hide my scent, and I got a lot of unwanted attention. Which meant I got into a lot of fights, and I got suspended from school countless times." Ace crossed his arms as he stared at his little brother. "Your attitude is as bad or even worse than mine! I don't feel like dealing with your teachers whenever you beat another kid's ass for being fucking weird with you."

"We get called in the office enough already," Sabo adds.

Luffy outs, he threw his head back. "Ugh, this is so stupid... I'm not wearing them. I don't care what anyone says or does. I'll beat them all up and move on with my day."

Sabo sighed and rubbed his face. "Luffy..." Sabo took a deep breath. "Look, I'm all about you sticking up for yourself. Especially now since you're an Omega. I want you to let everyone know you aren't some pieces of cake to mess with... but I don't want you getting into trouble at school, they're already fed up with you now."

"Didn't Nami wear patches when she presented as an Alpha?" Ace asked.

"Yeah... but not for long," Luffy says. "Zoro didn't."

Ace rolled his eyes. "Yeah, and how many fights did that stupid Alpha get into?"

"...He was suspended for 2 months..." Luffy says, he scoffed. "But I'm not going to get into a lot of fights! I can handle my anger."

Ace and Sabo both laughed. "You!? Handling your anger? Yeah, sure." Ace says.

"Fine, you can go to school with no patches today... but if you get into trouble. You're wearing the patches until you can control your scent." Sabo says.

Luffy smiles and jumps up from the couch. "Yes! Thank you! I'm going to prove to you that I can easily handle myself."

"Oh, really? Because right now, your scent is overly sweet." Ace says, rolling his eyes. "It's too much, cool it down."

Luffy rolled his eyes. "Shut up, it's not that bad."

"It's uncontrollable... Please be careful." Sabo says he reaches his hand. "Just take these, okay?" Sabo was holding a few scent patches.

Luffy stared at the patches. He sighed but took them anyway and shoved them in his pockets. "Ugh, fine, but I'm still not wearing it."

"Just in case," Sabo says.

"Come on, I'll take you to school," Ace says, grabbing his keys and heading towards the door. Luffy grabbed his bookbag and followed after him.

 

Luffy walks down the halls. He's been out of school for a week because of his heat. Luffy honestly doesn't care about being an Omega; it doesn't affect him. Luffy doesn't care about secondary genders; none of it matters to him. Luffy smiles when he notices Zoro at his locker. He skips over. "Zoro!"

Zoro lifted his head to stare up at Luffy. " Hey Luffy, where have you been--" Zoro paused, he stood up and leaned forward. "You presented?"

Luffy chuckles. "Yeah!"

Zoro leans his nose closer and sniffs. "Omega, huh?" He pulled away and grabbed his bag from the ground.

"Yep," Luffy walked alongside Zoro as they headed to their first period together. "Ace and Sabo were so annoying today, trying to force me to wear patches."

"Really?" Zoro rolled his eyes. "Fuck scent patches, you'll be fine."

"I know! But they think I'm going to get into fights." Luffy says, walking into the classroom with Zoro.

"They're right about that, you definitely will," Zoro says, flopping into the chair in the middle of the class.

"What?! No, I won't! I can control myself." Luffy says, sitting beside Zoro.

"No, you can't, dumbass," Zoro says, nudging Luffy. "Your pheromones are crazy right now. Cool it."

Luffy sighs and tries to calm his pheromones, but he's not even sure how to. "Ugh, who cares, just ignore it."

Zoro rolled his eyes. "Idiot."

The first period was irritating, he kept feeling some eyes on him, during the entire period, and hushed whispers. Luffy kept his anger in check. He needs to prove to Ace and Sabo that he can handle this because he really doesn't want to wear patches. So, he pretends to be unbothered, ignoring everyone's judgment. He also doesn't understand why the hell it's such a big deal that he's an Omega? Why is that such an issue? Why is everyone talking about it? Why is he being gossiped about? There's plenty of Omegas here... There are more Alphas and Betas here. But he's not the only Omega.

Finally, after an annoying ass morning, it's lunch time! The best part of the school day! Luffy happily made his way to their table, flopping down between Zoro and Sanji. Nami and Usopp snapped their heads to Luffy. "Luffy!? You're an omega?!"Usopp asked. "No way, I always assumed you'd be an Alpha."

Luffy shrugs as he takes a bite of his burger. "Yeah, so?"

"Your scent is nice... but it's wild, why aren't you wearing patches?" Nami asked, as she takes bite of her fries.

"Don't want to," Luffy says as he chews.

"Your scent is very strong," Robin says. "Has anyone tried causing you trouble?"

"Nope... but they have been staring like creeps." Luffy finished his burger.

"Yeah, your scent is super strong," Franky commented. "Do you know how to... calm it down?"

"Nope, and how should I? Just ignore it." Luffy says, starting on his second burger. Luffy is extremely annoyed at his friends who keep commenting on his scent... Maybe it's because they're Alphas. Their noses are more sensitive when it comes to Omegas... Every single one of his friends are Alphas, except Sanji, who hasn't presented yet, and Chopper, who is a Beta. The rest are annoying ass Alphas.

"You should really ask Ace how to control your scent. He's an Omega; he could help." Nami says, "Your pheromones are drawing a lot of attention." She adds, as she glances at the people whose staring.

"Screw them, who cares?" Luffy says, finishing his burger.

Zoro sighs. "Someone's going to make a move on you, and then we have to fight them, and it's going to cause a scene."

Luffy rolled his eyes. "If someone makes a move on me, I'll fight them; you guys can just watch."

Everyone at the table sighs heavily, and they quickly change the topic, talking about something completely different. After Luffy finished his lunch, He put his tray away and headed into the bathroom, ignoring the stares he was getting as he passed the other tables. Luffy sighs when he walks into the bathroom, thankful that it's empty.

Luffy used the toilet, walked over to the sink, and started washing his hands when someone walked into the bathroom. Luffy ignored them at first until he felt someone beside him. He turned his head, but he was pushed up against the wall hard, knocking his head against it, and then there was a nose up against his scent glands. Large hands on his hips, pinning him hard against the wall. A strong scent of cigarettes and coffee hits his nose, making him feel dizzy. This scent is strong. Very strong and intimidating.

Shit, Luffy is frozen and confused, he's not sure what to do, who the hell is doing this to him?! Luffy didn't recognize the scent, and he couldn't see the face. Luffy clenched his fist.

"Hey, get the hell off me," Luffy warned, his voice was a little shaky because he felt very dizzy with this scent filling his nostrils. "I said get the HELL OFF ME!"

Luffy gathered up all of his strength and kicked the Alpha off. Luffy lifted his fist and punched the Alpha in the jaw as hard as he could, knocking the asshole down. Luffy glared down at the Alpha, but then his angry eyes widened in surprise. He stepped back.

"Traffy?" Luffy asked, staring down at a classmate who always ignored him. What the hell?
