"I'm DONE," Oikawa huffed, slamming his juice box onto the cafeteria table so hard that it crumpled in his hand, juice squirting pitifully onto his tray. His expression was pure devastation — the sort of look you’d expect from someone who had been cruelly betrayed by a trusted comrade.
Across the table, Hanamaki raised an unimpressed eyebrow, mid-chew of his sandwich. Matsukawa, lazily sipping on his soda, looked over with mild concern, like he was watching a particularly dramatic soap opera unfold.
"With what?" Matsukawa asked, his voice the picture of bored politeness.
"Iwa-chan!" Oikawa exploded, throwing his hands into the air in a dramatic, almost balletic arc. A few nearby students glanced over, startled, but Oikawa didn’t even notice—he was too far gone.
"No matter how much I subtly flirt with him, he just—" Oikawa clutched at his chest like he’d been mortally wounded, "ignores it! It's like—like I'm speaking a different language! Like—like I'm SCREAMING into a void!"
He sagged onto the table, forehead dramatically thunking against the plastic surface.
Hanamaki, unfazed by the display, tapped his chin thoughtfully, like he was analyzing a math problem.
"Maybe," he said slowly, "you're being too subtle."
Oikawa lifted his head slightly, brown eyes hopeful, almost desperate for advice. Matsukawa chimed in, deadpan:
"Yeah. You should be, like... painfully obvious. Like, smack-him-in-the-face obvious. Make it so even Iwaizumi can't miss it."
Oikawa blinked. There was a long pause, as if the suggestion needed to physically download into his brain. Then, visibly, something shifted. The air around him changed — electric, dangerous. His posture straightened. His eyes gleamed with a frightening, manic light.
"You know what?" he said, his voice gaining speed, volume, and unhinged energy with each syllable. He smacked his palm onto the table with renewed fervor. "You're right."
He stood up so fast that his chair scraped loudly against the floor, drawing even more attention. His hair practically shimmered with the force of his newfound determination.
"It's time for WAR."
He pointed dramatically toward the horizon—well, the wall of the cafeteria—but it felt like the horizon.
Hanamaki and Matsukawa just exchanged a long, knowing look over their food, silently mourning the peace that once was.

Iwaizumi's POV:
Scene One: The Wall Pin
It was just another normal day after practice, the gym buzzing with the sounds of teammates gathering their things, lockers slamming, the buzz of conversation still hanging in the air. Iwaizumi was gathering his water bottle, wiping sweat off his face, trying to ignore the exhaustion creeping into his muscles. He just wanted to grab his bag, get home, and sleep.
But of course, Oikawa wasn’t going to let that happen.
Iwaizumi had barely turned toward the exit when a hand shot out from behind, grabbing his wrist and yanking him backward, causing him to stumble into a solid chest.
"Iwa-chan~," came Oikawa’s voice, almost sweet, yet dripping with something far more dangerous. "You're looking especially good today."
Before Iwaizumi could even respond—before he could process that Oikawa had just straight-up flirted with him—Oikawa had spun him around and pinned him against the cold brick wall of the gym, his palms pressing on either side of Iwaizumi’s head. Iwaizumi’s breath hitched, his pulse quickening in a way he absolutely could not control.
He could barely breathe, let alone speak, as his back pressed against the hard surface. His heart was racing, and his stomach felt like it had turned into a knot of pure electricity.
"O-Oikawa!" he stammered, his voice suddenly thick with panic. His eyes darted, avoiding Oikawa’s intense gaze, but his attempts were futile. Oikawa was right in front of him, so close their breaths were mingling. Oikawa’s proximity made everything feel a little too real.
"What’s wrong, Iwa-chan?" Oikawa’s voice was teasing, the warmth of it curling around Iwaizumi’s every thought. He leaned in closer, their faces mere inches apart, and Iwaizumi felt his stomach lurch in a way that was definitely not normal. "Are you feeling nervous? Because, I mean... I can’t blame you."
Iwaizumi blinked rapidly, trying desperately to cling to some semblance of rational thought. His face was on fire. His heart was hammering. His hands were trembling at his sides.
"S-Stop—" he started, but his voice cracked. His mind was a chaotic mess, fighting to pull himself together. He could feel the heat of Oikawa’s body close enough to burn him, the familiar scent of him—a mix of sweat, soap, and that ever-present cologne—seeping into his senses.
"Stop?" Oikawa mused, leaning even closer, his breath now ghosting over Iwaizumi’s ear. "But Iwa-chan, you're the one who's blushing. Don’t tell me you're not enjoying this."
Iwaizumi was completely lost. He couldn’t respond. His lips parted, but no words came out. His entire face had gone crimson, the blush creeping down his neck in the most obvious way. His skin felt on fire, and for the life of him, he couldn’t make his hands stop shaking.
"Iwa-chan," Oikawa whispered again, his voice low, the teasing edges replaced by something softer, almost tender. "You’re so cute when you're flustered. I think I might just have to do something about it."
Iwaizumi’s heart skipped a beat. "Wh-what do you—"
Before he could finish his sentence, Oikawa’s thumb traced lightly along his jaw, sending an involuntary shiver down his spine. It felt like electricity was crackling through the air between them, and Iwaizumi could no longer focus on anything other than the feeling of Oikawa’s hand on his skin.
It was too much. His mind was racing, yet it felt like it had all but shut down.
"Iwa-chan, if you're gonna keep blushing like that, I might just have to take advantage of it," Oikawa murmured, voice sweet but with an unmistakable, teasing edge.
Iwaizumi’s face was a hundred shades of red. "O-Oikawa..." He could barely even think properly, let alone speak. Every part of him wanted to push Oikawa away, to get out of this situation, but at the same time—god, he didn’t want it to stop. He was too far gone.
Oikawa’s smile widened, clearly savoring every second of the reaction he was getting. He took a step back, just enough to let Iwaizumi breathe, but still close enough that the air felt charged between them.
"I’ll take that as a yes," Oikawa said with a wink, and just before Iwaizumi could even process that—he was gone, slipping back into the crowd, leaving the completely flustered Iwaizumi standing against the wall, blinking like a deer caught in headlights.
Iwaizumi stood there for a long moment, hands still frozen at his sides, heart still racing, skin still burning.
He was so done.

Scene Two: The Backwards Hug of Jealousy
It had been a few days since the incident by the wall, and Iwaizumi was still recovering. He couldn’t even look Oikawa in the eye without his face betraying him. It was like his body had betrayed him, too—every time Oikawa’s presence lingered nearby, his heart would start thundering in his chest. He was trying to pretend like everything was normal, but that was hard when he could practically feel Oikawa’s mischievous grin in the air.
He just needed to survive until practice ended. That was the only thing on his mind when he walked through the school courtyard during lunch.
But of course, fate had other plans.
Iwaizumi spotted the girl immediately—her blush as bright as a beacon, her hands nervously clutching a piece of paper. She was standing a little too close to him for comfort, nervously handing him a folded letter. Iwaizumi sighed inwardly, wondering if he could just slip away before she said anything.
"I-Iwaizumi-kun, I… I wanted to tell you something."
She was clearly stammering, her face a deep shade of red as she stood fidgeting in front of him. Iwaizumi was too tired to process her words and just nodded, holding up his hands in that awkward “I’m not sure how to respond” gesture. He could feel the heat creeping up his neck, and just when he was about to politely excuse himself, he heard the unmistakable voice of Oikawa from behind.
"Well, well, well, what’s this Iwa-chan? Got yourself a fan?" Oikawa’s voice was dripping with amusement, though there was something sharper underneath the playful tone. Iwaizumi turned to face him, but before he could say anything, Oikawa was already beside him, wrapping his arms around his waist from behind.
"Oikawa!" Iwaizumi choked out, his face immediately flushing, already embarrassed from the earlier encounter. But what really made his heart stop was the way Oikawa rested his head on Iwaizumi’s shoulder. The sudden intimacy of it nearly caused Iwaizumi to short-circuit. His breath hitched in his throat, and he was too stunned to move, the sensation of Oikawa’s warm body against his back sending an immediate shock of heat all the way through him.
"What—What are you doing?!" Iwaizumi sputtered, practically spinning in place, though Oikawa’s grip stayed firm, his fingers lightly digging into Iwaizumi’s waist. Iwaizumi could hear the smugness in Oikawa’s voice when he spoke again, low and just a little too sweet.
"Oh, nothing~ Just showing off what’s mine."
Iwaizumi’s mind went blank. His ears turned a deep shade of crimson, his pulse speeding up for an entirely different reason than he was comfortable with.
The girl who had been standing nervously in front of Iwaizumi blinked at the scene, her eyes wide, and Iwaizumi could practically see the moment she realized something was off. Her gaze darted back and forth between the two of them, her face contorting in confusion, then something like realization. Then, without another word, she slowly backed away, eyes flicking to Iwaizumi as if she was apologizing with her gaze. It was clear she thought the situation was a little more serious than it appeared.
"Ah, um, sorry for bothering you!" the girl mumbled, already turning and leaving at a hurried pace, clearly embarrassed by what she’d just witnessed.
Oikawa didn’t let go. He smirked.
"Looks like Iwa-chan has someone interested in him," he teased, his voice too light for the weight it carried. His face was close enough for Iwaizumi to feel the soft puff of his breath against his neck, making it impossible for him to think clearly. Oikawa’s smile widened, as if he was savoring the look of pure mortification on Iwaizumi’s face.
"I-I wasn’t—" Iwaizumi stuttered, trying to push Oikawa away, but the other boy was persistent, holding on like he had all the time in the world.
"What? Iwa-chan, don’t tell me you were planning on dating her?" Oikawa’s voice was playful, but the undertone was unmistakably possessive, the hint of jealousy creeping in despite his teasing words.
Iwaizumi's mind was racing, his heart a mess of confusion and frustration. He had been talking to the girl earlier out of politeness, but now he couldn’t even bring himself to explain it, especially with the way Oikawa was looking at him, his hands warm and insistent around his waist.
"S-Stop!" Iwaizumi finally managed, his voice cracking under the pressure. He was a complete mess at this point—his cheeks were still hot, the blush creeping steadily down his neck, making him feel like he was burning alive. He wanted to shove Oikawa off, but his limbs refused to cooperate, and all he could do was stand there, helpless.
"Hmm?" Oikawa hummed, nuzzling further into his neck, like he was teasing him on purpose. He didn’t care that they were in public, didn’t care that they were standing in front of the school courtyard where anyone could see.
"Iwa-chan, you know," Oikawa continued, his tone soft but undeniably possessive, "if you want me to back off, you’ll have to do something to make me."
Iwaizumi’s brain short-circuited again. There was a loud ringing in his ears, and he felt like he might just collapse right there.
"I—" his voice was so shaky, he couldn’t even finish the sentence.
Oikawa only smiled wider. He was winning. And Iwaizumi was completely lost.

Scene Three: The Whisper and The Hit
It was the middle of a boring math class, the kind where the clock seemed to move at the speed of molasses. Iwaizumi had his arms folded on the desk, his head resting on them as he tried (and failed) to stay awake. His brain was completely fried after the chaos of the past few days, and Oikawa’s constant flirting was doing him no favors.
His attention drifted lazily to the front of the class as the teacher droned on about some equation he’d probably forget by tomorrow, but just as his mind started to wander again, a whisper tickled his ear.
"Hey, Iwa-chan..."
The voice was soft, quiet, and oh-so-sweet, sending a shock of warmth right through his spine. For a split second, Iwaizumi didn’t think much of it. It was just Oikawa being his usual annoying self, right? But then—Oikawa was right next to him, his breath fanning across his ear, and that was enough to make Iwaizumi’s entire body freeze.
His heart skipped a beat, then another, then another, until it felt like it was pounding so loudly in his chest that he was sure everyone could hear it.
Before Iwaizumi could even react, Oikawa's voice came again, so soft and casual that it made Iwaizumi’s stomach lurch.
"You’ve been staring at the clock a lot today. You want to skip class and get a snack afterward?"
Iwaizumi’s entire body went rigid at the suggestion, his face immediately heating up like he had a fever. He barely had time to think before his instinct took over, his hand shooting up to defend himself from whatever nonsense Oikawa was planning. His elbow whipped backwards in surprise as he jerked away, his fist colliding with something soft—something very soft.
There was a loud, resounding thud.
Iwaizumi’s eyes snapped wide open just in time to see Oikawa slump forward with an exaggerated whimper, clutching his head with both hands. The look on his face was pure, comical shock.
"Ouch!" Oikawa groaned, rubbing his forehead dramatically. "Iwa-chan! What the heck?! I was just trying to have a casual chat with you!"
Iwaizumi's face was on fire. He hadn’t meant to hit him that hard. He had definitely not meant to hit him at all. He quickly turned to apologize, but the words stuck in his throat, choking on the realization of what just happened.
"S-Sorry, I... I didn’t—" Iwaizumi stammered, his voice so small, it was almost drowned out by the noise of the classroom. The blush that had been lingering on his face since Oikawa’s earlier antics had only deepened, and now, it was creeping down his neck, making him feel like his entire body was burning.
Oikawa, of course, made the most of it.
"Iwa-chan, that was really unnecessary, don’t you think?" Oikawa said, his voice light but tinged with mock hurt. He blinked at him, eyes wide and exaggerated as he pouted dramatically. "I thought we were friends—you know, the kind who don’t hit each other in the head with elbows."
The class around them had gone quiet for a second, eyes flicking toward them in confusion, and Iwaizumi felt the heat of a thousand awkward stares. He could practically hear the whispers starting to bubble up from behind.
Oikawa didn’t care one bit about the attention. In fact, he seemed to be enjoying it, leaning in a little closer, eyes sparkling with mischievous delight. "You know, Iwa-chan, I’m starting to think you really don’t like me," he said teasingly, still pouting, his voice sweet and undeniably teasing.
Iwaizumi was torn between feeling mortified and wanting to crawl into a hole and never come out. His heart still hadn’t stopped racing from the shock of Oikawa’s whisper in his ear, and now this—his brain couldn’t even keep up with the mess of emotions swirling in his chest.
"I didn’t mean to—" he started again, but Oikawa’s dramatic sigh interrupted him.
"Iwa-chan, I know you’re embarrassed," Oikawa said, leaning even closer to him, voice soft but full of teasing affection. "But you really shouldn’t hold back so much. If you wanted to hit me, you could’ve just asked. I’m a big guy, I can take it."
Iwaizumi’s entire face burned hotter than ever before. He couldn’t form a coherent thought, let alone argue with Oikawa’s ridiculousness. Why was he still talking like this?!
"I-I wasn’t—" he tried again, but Oikawa had already moved on, flashing him a playful wink, completely undeterred by the fact that Iwaizumi was at his absolute limit.
"I’ll forgive you this time, Iwa-chan," Oikawa said, voice still sweet and smooth. "But only because you’re so cute when you get all flustered. I might need to fluster you more often."
Iwaizumi could only manage a frustrated growl under his breath, his hands trembling on his desk. He wanted to bury his head in his arms and pretend he was anywhere but here, with Oikawa making him a nervous wreck in front of half the class.
The bell rang a few minutes later, signaling the end of class, but Iwaizumi was still so shaken from the whole exchange that he could barely focus. He hurriedly grabbed his bag, muttering under his breath as he tried to make a quick exit, but of course—
"Hey, Iwa-chan! Don’t run away from me! I’m still waiting for that snack date!"
Iwaizumi’s mind finally caught up to his body, but it didn’t help the fact that his face was still so red it probably looked like he was going to spontaneously combust.
_______________________________________________________
Scene Four: The Ice Cream Plan
It was supposed to be a simple snack break, just a quick stop at the local café after school. At least, that’s what Iwaizumi had convinced himself of when he reluctantly agreed to go with Oikawa.
He had, of course, been duped. Again.
They sat outside at a small table, the weather nice for once—just cool enough to be comfortable. Iwaizumi was already regretting everything, though, because Oikawa was giving him that look. The one that meant trouble.
"Iwa-chan~," Oikawa’s voice trilled, sweet like honey, as he leaned forward, making his best innocent face. "I think I’ve suffered enough from your violent elbow attack... I think it’s time you made it up to me."
Iwaizumi rolled his eyes, leaning back in his chair. "Oh? And how exactly do you expect me to make it up to you?" He already knew where this was going, and he was bracing himself for the worst.
Oikawa pouted dramatically, his hand on his cheek, eyes wide and innocent. "Well, you know… I’ve been thinking. I think the best way for you to apologize would be to buy me a nice, delicious vanilla ice cream cone."
Iwaizumi blinked, caught off guard. "Ice cream?" He stared at Oikawa, not sure if he was joking or not. But Oikawa’s expression was dead serious, like this was the most important thing in the world.
"Yes," Oikawa continued, voice dripping with sweetness. "I really need it, Iwa-chan. You hit me really hard on the head, and I need a treat to make up for it."
Iwaizumi sighed, rubbing his temples. "Fine, fine. But this is the last time I’m buying you anything like this." He stood up and walked toward the counter, muttering under his breath about how ridiculous this was. But of course, he couldn’t deny that Oikawa had gotten under his skin.
When Iwaizumi returned with the ice cream cone, Oikawa's eyes practically sparkled with delight. "You’re the best, Iwa-chan!" he said, flashing that dazzling grin of his.
Iwaizumi rolled his eyes, sitting back down. "Just eat it already."
And Oikawa did, in the most extra way possible.
He took the ice cream cone in his hand, slowly, dramatically, licking the tip of it with exaggerated care. He sighed in pure bliss, his eyes fluttering closed as if he were experiencing the most heavenly thing in the world.
"Mmm, this is so good," Oikawa moaned, his voice low and almost too sensual for a simple ice cream cone. "The sweetness… the texture… It's perfect, Iwa-chan." He let the ice cream melt slightly, taking another exaggerated lick, making a show of how much he was enjoying it.
Iwaizumi felt his face go hot. His mind was trying to catch up with what he was hearing, but it wasn’t working. Oikawa’s voice, the way he was savoring every lick, it made Iwaizumi way too aware of the situation.
"D-Don’t do that," Iwaizumi stammered, looking anywhere but at Oikawa, his blush creeping down his neck. It was like the world was spinning, and all he could focus on was the way Oikawa was licking that ice cream. Why did it have to be so... intimate?
But Oikawa just grinned, leaning in ever so slightly, his voice still carrying that teasing edge. "What? I’m just enjoying my ice cream, Iwa-chan. You did get it for me, after all."
Iwaizumi's chest tightened, his heartbeat louder in his ears than Oikawa’s voice. "I-I didn’t mean for it to turn into this," he muttered, not even sure if he was talking to Oikawa or just trying to keep himself from combusting.
"Well," Oikawa said, that playful glint in his eyes, "Maybe next time you’ll think twice before hitting me on the head. You owe me more than just an ice cream, you know." He gave a slow wink, his tone teasing and light, making it seem like nothing had changed. But Iwaizumi could feel the weight of the words hanging in the air.
The rest of the ice cream cone was gone far too quickly, and every lick seemed to make Iwaizumi’s blush grow deeper. By the time Oikawa finished, he was practically purring with satisfaction. "Thanks for the treat, Iwa-chan. You really know how to spoil me."
Iwaizumi’s only response was a heavy sigh, his head in his hands, praying the ground would swallow him whole.
___________________________________________
Scene Five: The Confession
It had been a week. A whole week of Oikawa’s relentless flirting, teasing, and absolutely no boundaries whatsoever—and Iwaizumi couldn’t take it anymore.
He wasn’t stupid. He knew exactly what was happening. He’d been avoiding it, burying himself under layers of denial because there was no way in hell he could let himself fall for someone like Oikawa. The guy was a walking disaster—charming, loud, reckless, always one step ahead in their little cat-and-mouse game.
But the more Iwaizumi tried to resist it, the more everything about Oikawa seemed to get under his skin, to break through his carefully constructed walls. The way Oikawa would look at him, the playful touches, the teasing remarks, and that damn smile—the smile that made Iwaizumi’s heart race and his chest tighten every single time.
By the end of the week, Iwaizumi had had enough. He couldn’t pretend anymore. His feelings had become impossible to ignore, and no amount of rationalization could save him from what was about to happen.
It was late in the evening, after practice, when it all came crashing down.
The gym had emptied out, leaving only Iwaizumi and Oikawa to pack up. Iwaizumi was finishing up with his bag, trying to ignore the way Oikawa kept glancing over at him, that glint of mischief still very much alive in his eyes.
"Oi, Iwa-chan," Oikawa’s voice broke the silence, soft but undeniably teasing, as usual. "You look so serious tonight. Got something on your mind?"
Iwaizumi stiffened. He hadn’t meant to get caught up in his thoughts, but Oikawa always seemed to know exactly when to strike.
"Yeah, I do," Iwaizumi muttered, his voice quieter than usual. He ran a hand through his hair, his heartbeat speeding up at the thought of what he was about to do. "Look, Oikawa..."
Oikawa raised an eyebrow, a mischievous smirk tugging at the corner of his mouth. "Oh? Is this it? Are you finally going to confess your undying love for me?"
Iwaizumi wanted to punch him. It was ridiculous. He shouldn’t feel like this. He shouldn’t be standing here, having this conversation. And yet, here they were, and here he was—utterly helpless in the face of it all.
He took a deep breath, forcing himself to meet Oikawa’s eyes. The teasing glint was still there, but there was something else, something more vulnerable, lurking beneath that playful exterior. Maybe Oikawa had always known what this was, what was coming.
"I... I don’t know how to say this, but I’m not gonna keep pretending," Iwaizumi said, his voice a little rough, a little unsteady. "You’ve been driving me crazy, Oikawa. The teasing, the flirting, all of it. I... I don’t know what the hell you’re doing to me, but it’s working. I can’t... I can’t ignore it anymore."
Oikawa’s smile faltered for a second, his eyes narrowing as if he was carefully reading every word Iwaizumi had said. His gaze softened, and there was a quiet pause between them, the kind that seemed to stretch on forever.
Iwaizumi swallowed hard, the confession choking him on its way out. "I think I... I think I like you. More than I should, more than I can handle."
It was out now. The words hung in the air, heavy and raw, and for a moment, Iwaizumi thought he might explode from the sheer embarrassment. His chest was tight, his palms clammy, and his face felt like it was on fire. This was it. This was his downfall.
There was a long silence. For a moment, Iwaizumi was certain Oikawa hadn’t heard him, that maybe he had said it too quietly or too awkwardly for Oikawa to take him seriously. But then, Oikawa stepped forward, closer, and his usual teasing smile softened into something warmer, something genuine.
"Iwa-chan…"
The way Oikawa said his name sent a shiver down Iwaizumi’s spine, and before he knew it, Oikawa was close enough that he could feel his breath, warm and teasing. But this time, there was no game behind it, no teasing glint in his eyes—just that usual familiar warmth that Iwaizumi had grown to crave.
"You’re so obvious," Oikawa whispered, his voice low and soft, and then, as if to add to Iwaizumi’s mounting panic, he reached up and gently cupped Iwaizumi’s face, his fingers warm against his flushed skin.
Iwaizumi’s heart skipped a beat. His face burned even more than before, and it took everything in him not to turn away. But Oikawa wasn’t letting him go. No, instead, he was slowly closing the distance between them, like the entire world had paused for just this moment.
And then, just when Iwaizumi thought his heart might burst, Oikawa spoke again.
"You think you’re the only one who’s been feeling this way?" Oikawa asked, his voice playful but full of something else—a vulnerability that Iwaizumi hadn’t expected to hear. "I’ve been trying to get you to admit it for days, you know."
Before Iwaizumi could even respond, Oikawa’s lips brushed against his forehead, gentle and fleeting, leaving a warmth that made Iwaizumi’s knees feel weak. And then, Oikawa pulled back slightly, his grin returning, but this time it was softer, a little less teasing, and a lot more... affectionate.
"I guess I’m not the only one who can’t handle it anymore, huh?"
Iwaizumi opened his mouth to say something, but his words caught in his throat. His face was on fire, but somehow, the tension between them had shifted. It was no longer just about teasing. It was real now, raw, and it felt... right.
Iwaizumi swallowed hard, his voice still shaking, but this time with more confidence. "Yeah. I guess not."
