♡ crossover // enemies to lovers ♡

The building was shining before him, Hinata yelled anything but words and the team behind him couldn't help chuckling at his child-like enthusiasm, they were all fired up but Hinata and Kageyama showed it more in a physical sense - especially since Nishinoya and Tanaka had just been woken up from a decent snooze and Hinata ran off to get the first look among the students from Karasuno at the volleyball court that they'd be playing on against the other teams that had also come to participate in the training camp.

They studied hard for this - they, meaning Nishinoya, Tanaka, Kageyama and Hinata - and it had all paid off; even those times when Kageyama was almost close to literally murdering his partner because of the stress and the pressure, and now he was racing ahead, yelling at Hinata for getting a head start without any warning as he almost caught up.

Luckily, they could already see the doors and they were open so there was no way they could get lost and Hinata yelped when Kageyama almost bested him, he pushed himself further and felt the way his bag kept hitting his backside as he ran with a purpose, his face scrunching in concentration to make it to the door as the dust of the floor kicked off of his feet and he heard the thumps of the black-haired boy running behind him, huffing, yelling swears when he knew he wasn't going to make it - and yet they still ran without stopping before they were finally inside.

They jumped through, Hinata made it first as he leaped in like a satisfied smug winner and he huffed, regaining his breath as quickly as he could to turn to Kageyama who was know leaning over, palms on his knees as he heaved in the needed oxygen to speak properly, a prominent frown on his face, "dammit."

"Ha! Ha! I won, Bakayama, that's 72-71, my point!" He had turned, hands on his hips to grin at his partner, successfully ignoring the glare he received even if it did manage to bring chills down his neck and he turned back to the court,

To see it already occupied with another team.

And they were watching them.

Oikawa saw Hinata with Kageyama, a frown slowly coming to his face when he watched the two converse as if this was some type of field trip, he ignored the innocents gaze of wonder that Iwaizumi gave him and once he turned away defiantly, Hinata and Kageyama had only just noticed them.

The entire team of Seijoh were there on the court, the middle one as the gym had three right beside each other, it was huge and enough to make the palpitations in Hinata's chest fasten as his bright eyes widened in awe, "waaah~! This is huge! Just like the one with Nekoma and Fukurodani, right, Kageyama!?"

He looked to his side, facing upwards to see his partner watching the same view as he had been, only it was just his eyes that were shining as opposed to Hinata's entire being,

"yeah." Hinata smiled proudly and noticed the Grand King, there was no way he could mistake him for anyone else after all. Oikawa had thrown the ball up and he was running, he stopped before the backline of the court and jumped, his entire body; lean and slim, elegant - in Hinata's eyes, and he slammed his palm into the ball with a breath-taking spike and Hinata watched eagerly when the ball flew so fast, he almost couldn't follow it.

The sound resonated within the gym to escape the windows and the doors and Hinata had to inhale deeply to regain himself, his cheeks dusted pink and he noticed another shadow on the other side of him, "amazing.." He subconsciously murmured and the person spoke back, "of course."

He flinched, however, when the familiar voice reached his ears and both Kageyama and Hinata stepped back when Oikawa turned to them with a smug smile, "you see that, chi-eck!"

He almost dropped the other ball that was thrown to him, dread overcoming him when the three of them watched as Ushijima Wakatoshi had stood by to watch the ace player with a nonchalant expression, or rather, one of seriousness and determination, "Urgh, Ushiwaka, leave me alone," Oikawa didn't hesitate to flick him away like a fly from where he stood and Iwaizumi was tempted to throw his ball at the setters' head before Oikawa had turned away and muttered under his breath, "way to ruin the picture.."

Kageyama, however, failed to notice the way his expression fell and stepped forward, only once, "Oikawa-san, can you show me that again."

Oikawa turned, narrowed his eyes and stuck his tongue out, "and why would I do that. Tobio-chan?" He spoke sassily, his voice hard and flippant, Kageyama was unfazed and Hinata gasped at his partners' bravery, "t-the Grand king! Kageyama, wh-what're you doing?!"

Daichi came in moments later, skidding across the floor to ensure his underclassmen weren't up to any mischief with the other teams.

As they had arrived to the training camp with plenty of time to play, Hinata and Kageyama had already dashed towards the last court to begin their stretches. Their bags were left at the bus and Ukai; albeit grumbling and swearing the entire time, took it upon himself to take them inside so that the boys could play as they had been excited for the training camp ever since it had been announced; and that was a couple of months ago.

But the switching of team players towards the end of the day was completely unforeseen when Oikawa ended up being paired with Hinata. He was disgusted but a little relieved that he hadn't been put on a team with his kouhai. At least this was a time to unwind, a playful match with no seriousness to be held within the teams.

Nonetheless, as there was five different teams that were invited to the training camp; including his own, the different players in his teams ranged from Shiratorizawa where he looked at Tendou Satori, a middle blocker, who had been watching Tsukishima on the other side of the net.

Oikawa scrunched his face and looked next to the red-haired guess monster to see Futakuchi Kenji from Date Tech, a wing spiker, and he glared at him, annoyed by the good-looking player who had been making snark remarks under his breath about the people that stood across form him.

Oikawa leaned his weight from one leg to the other and looked at the person right beside him, Terushima Yuuji who played as the captain and wing spiker of his team, and then Oikawa looked at the boy beside him, he was pointing two thumbs up towards Hinata; who had also been appointed to his team, and Hinata did the same back to Nishinoya.

Both of them were probably relieved to play with their own teammates but the game started and Futamara Takeharu from Johzenji served the ball and it went straight to Oikawa, he set it to the player who was ready for it and even when Hinata was ready for it,

"To me!" He exclaimed, already in the air, Oikawa's eye twitched and he purposefully set it to another, "Futakuchi!"

The latter wasn't as prepared as Hinata and yet he still spiked it, slamming it down and he scored the point, he cheered momentarily, "ah, first point to me." He gleefully spoke with a smug air and Tendou clicked his tongue at his tone,

"Hey!" Oikawa turned to see the glare Hinata was giving him, "what the hell?! I asked for the ball!" He whined and Oikawa found it fascinating to see how the chibi wasn't as nervous around him as he had been when they were off of the court, perhaps he was just excited to be on the same team as him, "you weren't ready," Oikawa hummed, turning his chin up high and Hinata gaped, "Y-You-!"

"Oi, shrimpy-chan, you'll get the ball when it comes to you," Tendou cut in with a lazy tone, "let's go."

"Dateko.." Futakuchi murmured to himself,

"O-Oi!" Nishinoya laughed when Tendou's eye twitched, "let's get another point!"

It was safe to say that Hinata rarely got the ball then Oikawa was setting. No one knew and all they could see was the fact that Hinata was brimming with annoyance and he was twitching to play, to feel the sting of the ball on his hand.

Oikawa refused to give him the satisfaction for some unknown reason.

During dinner as it was cooked and served by the managers, all the boys from the five teams got in, their shoulders sagged and they went back to their respective teams to rant about what they had done in their new makeup teams for the friendly matches,

"Iwa-chan~ my team was so annoying! Especially," he glanced over his shoulder, "that chibi-chan!"

Hinata gaped, frozen with a scowl, "wh-what?! What did I do?!"

Kageyama watched the exchange silently, his mouth full of rice, "if cauf your shtupif"

"I'm not stupid, Bakayama!" And when he seemed to quickly forget about Oikawa, the fluffy-haired boy wouldn't let him have that, "yeah, he's so~ stupid!"

Hinata whipped his head back to the third-year setter, "y-you're stupid!" He quipped back and  Oikawa huffed, a glare directed right Hinata so hard that Iwaizumi had to smack him out of it, "you're such a shitty guy.." The tired ace walked away from his childhood friend and the other followed stubbornly when he caught Hinata hiding behind the nearest person who happened to be Kageyama.

When the five teams had arrived to their sleeping quarters, they were all separated into five separate, spacious rooms and all throughout the night, the lack of literally being able to play in the volleyball games kept an orange-hair boy up. He couldn't sleep no matter how much he tried and no amount of turning or what position he was in could change that.

He huffed and sat up, angered and cold as the futon had moved horizontally as his legs were free to feel the attack of the cold in the night. The tiny amount of light that managed to come through the edges of the curtains from the moon aided in letting him see where he was walking when he managed to trip over Daichi and crash into the door.

He froze, looked behind him and was reassured by the snore erupting from Tanaka's mouth. He opened the door and quickly shut it behind him, a yawn coming out of his mouth when he walked along the chilly floor of the hall to come to the vending machine.

The sound of a click startled him, he turned to see nothing and then looked back to the vending machine with longing, only a figure had popped up right beside the machine and the light caused a shadow to come over the new figures face, making him unrecognisable,

"AAAAHHH!!-MMMPPHH!"

"Shut up, chibi!"

Oikawa's voice startled him when his voice was muffled against the palm of his hand and Hinata backed away, trembling. Oikawa removed his hand from Hinatas face and doubled over with laughter, "BAH-hahaa, you should've seen your face, i-it was s-s-so funny! Bahaha, oh my god, th-that was priceless!"

Hinata gaped, he couldn't believe Oikawa had purposefully scared him just for his own amusement and he huffed, angry and tired, annoyed and angry, "what do you think you're doing, Oikawa!"

The third-year was still laughing, struggling to keep himself quiet, "aaah~" he finally relaxed, "that was so worth it.." He walked away, leaving Hinata to wonder what the hell just happened.

These things happened a lot during the week of the training camp. Oikawa would secretly creep behind Hinata to scare him (and succeed) and in response, Hinata would snoop around Oikawa while he was eating to take a bunch of the meat from his plate and run away chomping on it.

Oikawa would purposefully bump into the chibi; sometimes managing to make him fall, with a triumphant look on his face and then when Hinata often walked by, he would attempt (and most likely fail) trying to catch his leg between the older boys' legs to make him fall.

Hinata fell to the floor laughing (only after realising he wasn't about to be murdered) when he successfully made Oikawa fall on his ass.

They teased each other relentlessly throughout the camp and the other players watched, noticing the distance between the two boys that had lessened considerably and how they had always been watching each other - because of their antics, obviously.

It became a regular source of amusement for the bystanders and even their own teams; Seijoh and Karasuno, had grown oddly used to it; annoyed because of it, but it used to it. The reason it happened and why it continued, was completely unknown to everyone.

The day of the final games came quicker than expected, especially for Oikawa and Hinata. They had upped their game - possibly with or without knowing - and it might've looked like bullying to any common bystander but to them, it was friendly banter now.

They insulted each other playfully, laughing together by the time they couldn't think of anything else to say and they had started sitting beside each other during meal times. The two walked with each other to the gym or to the small convenience store down the street; still making each other laugh when one attempted to trip the other,

"oops," Oikawa spoke in an almost sultry tone, eyeing the younger boy in front of him, "gomene~," Hinata could practically smell the sarcasm, "you're so tiny, I almost walked right into you."

Hinata huffed, "maybe it's just time for you to get your eyes re-checked, megane-kun."

Oikawa gaped, appalled by Hinata's words and Hinata couldn't keep up the serious act before he broke into a smile. But, unlike the other times he had smiled, Oikawa's chest felt warm, he felt tingly - his stomach, he felt... butterflies?

Hinata's smile just radiated happiness and it made Oikawa feel giddy, because he was the one who caused that - well not directly but it was him who initiated the moments to come to this - and he just stared.

He almost smiled and his eyes widened at the sight of the grin on the younger boys' face, it was just so... cute. Hinata was so cute.

Five different buses were taking five different teams back to their schools. They were all situated in the Miyagi prefecture and even if they all lived within the same location, Oikawa almost seemed hesitant to leave.

In the morning, he practically gorged himself with Hinata's breakfast and the orange-haired boy wasn't even shocked anymore, only responding by moving his arm around Oikawa's chopsticks to take Oikawa's plate. The two still sat side by side, legs touching and shoulders rubbing against each other.

In their rooms packing their things, Oikawa followed Hinata into his room, to his futon. The rest of Karasuno were there and it had become a natural thing now, the two would accompany each other to their rooms and the teams seemed a lot closer now, even Daichi and Iwaizumi hadn't been getting close as a result of the two boys were seemed to be past their trivial banter and onto another stage in their 'friendship.'

"shrimpy, give me your phone," the nickname had stuck and Hinata didn't know if he minded or not, he handed him his phone anyway and watched with a raised brow when he heard another phone ringing close by, "there we go!"

Oikawa gave him his phone back and then took out his own phone, "now I have your number~! I bet you're happy, right? I don't just give my number to anyone, you know?" Oikawa saved Hinata's contact under chibi~♡

"Hinata, stop spacing out!"

The team; by Kageyama and Hinata's request, had piled into the gym at Karasuno to blow off some steam and Hinata grumbled to himself, shaking his head in order to focus, "aarrgh, be quiet, Oikawa!"

No one replied and Hinata only realised what had just occurred when the entire team was staring at him. Asahi scratched his head in question, "O-Oikawa?"

"A-Ah!" He turned red almost instantly, "m-my bad!" He scrunched his eyes closed in embarrassment, "Baha~! Hinata, you grew used to him, didn't you, huh?" Tanaka grinned widely and slapped his kouhai reassuringly on the back, Kageyama watched and his eye twitched, "Baka! Stop thinking about him and focus!"

"O-Oi Kageyama, it's alright," Daichi spoke up, he was tired, just like everyone else and not because of practice. Having to get up early and drive for an hour and a half made them all equally weary, "besides, we just need a rest and we'll be back on Monday."

That was the end of that and the weekend past without any text messages exchanged into phones that had been unknowingly held for almost the entire weekend.

"H-Hinata, stop spacing out, dammit!" Kageyama yelled again, a sense of deja vu hit him and it angered him further, "stop thinking about Oikawa-san!"

It was a rash use of words, they stumbled for his mouth quickly without giving him time to realise and his mouth fell open when Hinata failed to argue, only able to turn pink up to his ears.

"Y-You're not serious, right..?"

Sugawara murmured, almost breathless and Hinata whined, still unable to prove that what his partner yelled was wrong - that he wasn't thinking about the captain of Seijoh - he was, Suga looked at Daichi, almost in disbelief and yet the brown-haired third year failed to recognise this, "Daichi!"

He flinched, staring at the vice-captain with furrowed brows before his jaw also fell slack a little, "Ah-" he coughed, "Hinata," the small boy looked at him, frightened and he bowed quickly, "I-I'm sorry, captain! I-I'll try to c-concentrate!" His face was still pink, it didn't seem to show any signs of going away.

Daichi didn't know what else to say, Sugawara stepped in, half-heartedly murmuring to the captain as he neared the middle blocker, "useless..."

Daichi gaped but he couldn't defend himself.

Sugawara placed a warm hand on Hinata's shoulder, "Hinata, have you texted Oikawa?"

His tone was gentle, it was soothing, Hinata merely shook his head like he was scared just at the thought of doing such a thing. And it was weird because he was completely fine with Oikawa before, but now whenever Hinata found himself thinking of him (which occurred almost all the time now) his heart would race immediately, "and why's that?"

Kageyama crossed his arms behind Sugawara, almost as if he was daring Hinata to try and lie. Neither of them could lie to Sugawara though, "I-I don't know! I feel so nervous it makes my stomach hurt!"

Nishinoya raced to Hinata's side, "Ah! That's alright, Shouyou, I'll help you!"

Hinata's eyes sparkled and he revelled in the attention he had received, all good intentions to help him, "hand me your phone, Shouyou!" The bright-eyed boy raced to the bench to grab his bag, opening a pocket to out his mobile and it reminded him of when Oikawa asked for his phone and how happy it made him.

He didn't even realise it until now, "now, Shouyou," Nishinoya's expression turned serious and it travelled to Hinata, the latter standing straight and stiff when Nishinoya took his phone from his clammy hand. Tanaka raced in to lean an arm on Nishinoya's shoulder, watching for support, "what you're experiencing," the second-years' expression turned wistful and Hinata felt especially special to be able to receive such help, "is a crush."

"Eh?"

Hinata's head tilted, he paled,

"EH? w-with the GRAND KING?!"

Tanaka laughed obnoxiously loud, throwing his head back as he watched what Nishinoya had just done, "Don't worry, I'm sure it'll be okay!" Nishinoya's bright smile eased Hinata's nerves and he took his phone back, almost dropping it when it rang shortly, indicating a message,

"O-Of course...? Sho-" he almost lost his breath, his eyes bulging, "Shou-chan?!"

Hinata read it, read it again and felt his heart race at the sight of the heart emoji used after the text he had just received from Oikawa.

"W-wait, this is Oikawa!?"

"Yes! You're welcome, Hinata! I'm so proud of you!"

No one knew what was going on until Hinata fainted as he finally read the text that Nishinoya had sent, everyone passed the phone around to read it when the boy with the bright orange hair and a head full of Oikawa had passed out,

'Oikawa! Do you want to go out with me?!'

'of course, Shou-chan~♡'
