Reigning in the Great King - Oikawa x OC Fanfic

What Braincells?

"Just...wh-," Oikawa sighed leaning on the door frame. "Rae-chan, you know it's common courtesy to  give a heads up when going to an acquaintance's house."

Rachel let out a strangled sound of offence.

"Squeeze me sir, but I did give you a heads up hours ago and gave updates on when I would be here," she huffed. "Also it's not healthy to deny our newfound friendship."

Well Oikawa was napping most of the afternoon and he hadn't bothered to check or bring his phone down when Iwa came. So he guessed that was on him.

"This friendship seems rather one sided."

"Only because you-"

Rachel's remark was cut off by a voice in the house.

"Tōru who's at the door?" Oikawa stiffened at his mom's question.

"Rae-chan, unless you know how to exorcise a demon and a witch, now's not a good time."

"Hilarious coming from the demon king," Rachel snickered.

"Hey!"

"What? I think it suits you."

"Fine only because I'll be king so that I can order you to exile," Oikawa smiled deviously.

"That's not fair! Demon king or not you can't exile me without just reason!"

"Too bad since subjects can't argue back," Oikawa taunted.

"Well I promote myself to advisor so I can argue," she challenged.

"You can't just promote yourself! It doesn't work like that."

——————————————————————————

Iwaizumi stood in the living room confused, his anger towards Oikawa settled to a degree. He was joined in his stupor near the doorway by Ms. Oikawa.

She had come out of the kitchen when Tōru didn't answer her question on who was here.

They were able to discern the voice as a girl's and picked up pieces of what was being said from the entrance. So far, from what Iwaizumi gathered, it sounded stupid.

Dumb as it was Iwaizumi still never heard Oikawa talk to any girl like that. Oikawa would usually do his best to be sickeningly sweet towards any girl. That notion was enough to intrigue Ms. Oikawa and make the first move towards the door.

———————————————————————————

"Tōru, it's rude to keep guests waiting at the door." His moms sudden appearance had startled him out of his banter with Rachel.

"Mom! She was just abou-" Oikawa wasn't even given a fighting chance before his mom cut in and moved to stand before Rachel.

"Hello, I'm Iori Oikawa, Tōru's mother."

Rachel too was startled by the sudden appearance. The woman claimed to be a mother but could definitely pass as a sister.

"Hello, I'm Rachel Brooks. Nice to meet you Oikawa-san," she introduced and gave a quick glance towards Oikawa.

"I'm a friend of Tōru's," Rachel added cheekily.

Oikawa wanted to pass away.

"I stopped by to drop off some things for him to help with his knee," she said as she brought up a bag.

"Oh! How kind of you. Why don't we take this to the living room. Come on in."

Ms. Oikawa quickly guided Rachel to the living room. Neither Rachel nor Oikawa had any time to protest.

Rachel really hadn't planned on intruding. Especially since Oikawa said it was a bad time for her to be showing up.

Ms. Oikawa seated her on the couch next to a perplexed stranger before scurrying back to the kitchen. Oikawa just dragged himself to the armchair on her left and sank into it in defeat.

The two strangers on the couch exchanged simple pleasantries and names as their mutual friend buried his face into the throw pillow.

"Is he having a moment with the pillow?" Rachel asked as she turned towards Iwaizumi.

"Nothing out of the ordinary really," Iwaizumi grinned.

The only response from Oikawa was a muffled protest of some kind.

"Soooooo....,Iwaizumi-san are you also a student at Aoba Johsai like Ru?"

Oikawa's head immediately shot up.

Iwaizumi gave a questioning look at his best friend who was avoiding making eye contact. Ru? As in Tōru? Just what the hell is going between them?

"Uh yeah," he answered lamely.

"Cool. I'm starting there next week for 3rd year so I'll probably see you around. Pretty nice to to have met you before hand Iwaizumi-san."

"Hey, how come Iwa-chan gets the honourifics but I still don't?" Oikawa grumbled.

"Cuz he's nice?"

"You sure have a strange way of showing thanks to the person who helped you," he grunted.

"My friendship is payment enough," Rachel replied sweetly.

Oikawa pulled a face. "I want a refund."

"Rude!"

"Rich coming from you," Oikawa laughed.

Iwaizumi watched silently as they bantered. It was like they were playing hot potato with their shared brain cell. It was still difficult to put a label on what kind of relationship they had but he'll confirm it with Oikawa later if he had to.

"Anyways I actually got you stuff as thanks you know," Rachel defended and pull up one of her bags.

Oikawa watched as she brought out a rectangle box, probably the foam roller she was talking about, and a knee pad?

"Make sure you use them okay. Rolling out your muscles helps prevent injuries. Stretching sometimes isn't enough especially if the muscle is overworked," Rachel explained as she stood and handed him the items.

Oikawa blinked almost owlishly. Past Rachel he could see Iwa-chan giving him a level stare obviously meaning that he agrees with her.

Looking back down at the things on his lap he picked up the knee pad.

"And this is?"

"A level 1 knee brace. It's good for pain relief and adds some support. Level 1 is the most flexible and best for sprains."

Oikawa nodded slowly whereas Iwaizumi was somewhat impressed with her comprehension.

"Thanks for this Rae-chan. You're a pretty good friend," he gave her sincere smile and Rachel returned it.

"But you picked white and my knee pads are black. They're gunna clash," Oikawa whined.

"Aaannndd you ruined it. We were having a moment!"

"Not my fault you picked the wrong colour."

"I had a 50% chance, sue me. You're still gunna wear it!"

Iwaizumi rubbed his brow and sighed. It's like they could go at it forever. If this was going to be them at school....Gods help him.
