Yabai Koi Series

A/N: Hey there, I'm back with a new chapter. Maybe two, I dunno. Thank you very much for all the reviews, I really appreciate it. It's a boost to my constantly-depleting confidence, since there are some pretty damn good writers out there. The next chapter is halfway done so let's keep our fingers crossed that I finish it and upload it before the week ends. Haha. Oh, there'll be some suggestive scenes here and there for this entry, but most of it is clean. So here you go. ^^

Disclaimer: I do not own Haikyuu! and its characters.

Summary: Because according to Kageyama-kun, everything about Oikawa was 'yabai'.

#5: She had no idea how he could make something as mundane like drinking water seem so erotic.

[Note] This chapter is set after Karasuno beat Shiratorizawa in the Spring Tournament.


It was like clockwork, how she'd spot him and just end up staring at the way the smile lines appear on his cheeks, the mirth reflected in his eyes as he played with the kids, the proud grin on his face whenever one of his children managed to block an attack, or successfully get a spike in or when they would dive fluidly to receive a ball. He would turn around to high five them, and then their eyes would meet. He would always, always have his lips turned up into that smirk of his, as if he knew she was ogling at the way his shirt stuck to his body, the beads of perspiration glistening on the back of his neck and the bow of his upper lip.

Aah, Hitoka knew she was screwed.

Out of all people, why did it have to be him that her eyes would follow?


Class was as normal as always, with her classmates all clamoring to be the first to get their hands on the limited edition Karasuno Bun during lunch break (the school had pretty bizarre ideas when it came to promoting their school to the neighborhood, even more so with the Volleyball Club boys winning games after games after years of stalemate). A few of her classmates had accidentally set off the fire alarms, and got themselves a week of window cleaning. People would think that the students from the advanced class were different from the others and didn't fool around, but in fact they were just as normal. There was the usual sight of the oddball duo racing each other towards her class for their tutoring session with her, and groaning in unison as she passed back the quizzes she had prepared for them on a weekly basis.

After class, Hitoka changed clothes and headed to the gym for club activities, stopping by Hinata's classroom to fetch him (he was on class duty that day) and they both headed to the gym, Kageyama joining them midway. The boys went to change in the locker room, and having changed earlier, she went ahead to the large building. She arrived slightly early, and made quick work of preparing the court.

The light-haired girl was pulling out the net, when a bird flew into the hollow gym and swooped low just enough to whizz closely past her head, wrenching a startled "Hiee!" from her. Her small foot got caught in a hole in the net, and she fell down onto the shiny floor in a heap of tangled mess. Hitoka was trying to untangle herself without trying to strangle herself to death when the third years came inside, Asahi crying out a panicked "Yacchan!" and after a few of tugs here and there (and a very, very antsy Asahi) Daichi and Sugawara managed to free her from the clutches of the net. The Captain and the (now calmed down) Asahi took over putting it up, and Sugawara helped her up with a tug of his hand.

Going down into one of her signature Dogeza, Hitoka apologized for being clumsy and a sorry excuse of a manager (for the umpteenth time). Sugawara's carefree laughter filled the gym as he patted her head, giving her already mussed hair an affectionate rustle and grinning when her face warmed up exponentially.

"'Sokay, be careful next time, yeah?"

She nodded, giving him a salute and her clumsy "Yesh! Thank you!"

Hinata came bouncing in, and Hitoka quickly helped set the chairs for a visiting school later that day. She just came back from filling in the water bottles when Nishinoya and Tanaka both jumped into the gym and eagerly greeted Kyoko. As usual, she answered their boisterous greeting with a cool and collected nod, and they seemed happy just getting a reaction from her, rolling around on the gym floor before Ennoshita poked at their prone bodies, all but turned to putty, and dryly told them to get warming up instead of goofing off.

Nishinoya sprung back up just as energetically as they were seconds ago, and waved at Hitoka as well. "Yacchan! Great job ya did there at the club!"

The girl stood ramrod straight at the sudden shout out, and she gave a strained smile when the second-years and the freshmen turned to look at her, eyebrows raised. Self-consciously, she laughed and tried to brush it off with a wave of her hand. She didn't want them to know yet, but since she did bump into the loud shorty on her way out of the gym, then her initial gambit to break the news to the boys come fall was probably asking a bit too much.

"Thanks… but um… it's nothing big though senpai."

Hinata, all energy and smiles grabbed at the net to blink wide eyes at the Libero. "What? What? What is it?"

Hitoka adored the boys to bits, but sometimes she just found it a little irritating that they were so oblivious to her discomfort. Well, Yamaguchi-kun noticed her fidgeting figure and tried to ease the excitement, but when Nishinoya all but told them that their small manager had signed up to be a volunteer at the Little Tyke's, the manager gave up. She mouthed an 'it's okay' to the apologetic-looking Pinch Server, and if she was being honest, the sight of Hinata's outburst of "How COOL!" and starry eyes as he turned to her as if she was a goddess had done it for her.

How could she even win against that?

A resigned smile painted her small face, and she scratched the back of her head, laughing a little. "Well, yeah. Sort of. I wanted to learn more about Volleyall so I signed up for the club. It's been a few weeks since I started."

Tanaka scratched his head, and swiftly dodged one of Asahi's stray serves. "Isn't it a club for elementary kids and junior high brats?"

Asahi messed up his serve again, and the ball bounced against a wall near Daichi before it rolled over to her. She picked it up, tossed it to Sugawara and twiddled with her thumbs.

"Well, I couldn't really sign-up for other clubs since the schedules weren't tallied with mine. I'm not that athletic, I'd probably hit my teammates in the face more than actually getting a proper receive."

From the back of the gym Kageyama spoke up, "Yeah, she probably would."

Hitoka shrugged a shoulder and continued, "And I'd really like to learn more about… you know… about being a better manager." Kiyoko looked up from a clipboard, raising a brow as she heard Hitoka. The younger girl failed her arms about. "B-But, it doesn't mean that you're not a good enough teacher, senpai! You've been a really good instructor! The best! Not that I've been a manager before but well, um… yeah."

The third-year smiled a little at that.

Clearing her throat, Hitoka smiled at Hinata who looked as confused as the others. "I guess you could say I want to learn more about Volleyball and at the same time learn to observe the players."

Because to her, looking after the boys were similar to looking after the kids at Lil' Tyke. But she wouldn't tell them that, of course.

"Oh, it's like that, you know? Killing two birds with one stone!" Hinata quipped from his place.

She nodded. "Exactly."

Ukai arrived then, and immediately the boys started on warm up, Kageyama and Hinata racing each other as they ran laps around the gym.


She felt like throwing up. After the small commotion about her being a volunteer at the Lil' Tykes, Hitoka almost forgot about her jumpy nerves when Kiyoko had told her about the visiting school. Now that they were just minutes before the practice match, the nerves came back.

"So hey, Yacchan. How're the kids?" Tanaka draped an arm across her shoulders companionably, leaning in. "Still as rambunctious as always?"

She staggered at the sudden weight, and ignored the fact that the Wing Spiker was all sweaty from the short three-on-three match he played. After being with them for a while she became accustomed to the breach of personal space. They had just finished with warm ups and practice runs, and were waiting for the visitors to arrive for the practice match. Apparently their bus driver ran into some problems, but they did say that they were going.

Ennoshita sighed and rolled his eyes. "Of course they are, Tanaka. The kids in this neighborhood can barely settle down long enough for a lesson."

Hitoka nodded. "A few of them twisted some ankles. They bump into each other a lot." A giggle, "a group of boys were made to sit out when one of the coaches caught them fighting over who should serve first in a practice match."

She left out the three middle-school girls who had screamed indignantly when a coach had banned them from coming again after they harassed one of the coach assistant, a handsome guy who were popular with most of the younger kids.

Tanaka threw his head back and laughed. "Well, I know one way Yacchan could get them to behave." He leered outrageously, wagging his eyebrows. Ennoshita sighed as his friend switched from their manager to drape an arm across his shoulders instead. He disinterestedly watched, a ball in a hand as the bald player wagged his eyebrows again. "Hell, all you need to do to get brats to behave is flip your hair and undo your buttons – oof!" The second-year spiker gasped for breath, wincing a bit at the sharp jab to his ribs.

"Don't even joke about that, Tanaka. They're kids! That's disgusting." Ennoshita frowned at the man he'd just elbowed in the ribs, a slight blush gracing his cheeks.

A sputtering and blushing Yachi thanked him, he nodded to her and turned to his friend again, his calm features betrayed by the glare in his dark eyes. "Go harass someone else. Or, here's a thought, actually go practice your serves instead of hanging around Yachi all the time and tease her. As well as trying to get Shimizu-san to spank you." He shrugged Tanaka's hand off his shoulder, and tossed the ball in his hand into a ball cart to the side of the gym.

"In fact, I think Daichi-san's going to catch onto you goofing off too much. If you keep that up I bet he's gonna come up with something to get you to behave …"

"No, no. That's not necessary, ," Tanaka stood straight, reclaiming his breath and stepping back, hands in front of him like a shield. "That's okay, I'll behave." He flashed a quick grin, moving to hide behind Sugawara.

The Vice-Captain just rolled his eyes, making no move to shield his underclassman. Ennoshita had gone to Asahi to help the taller senior collect the used balls from the other side of the gym.

"You've gotta learn when to keep your mouth shut, Tanaka. Well, Nishinoya too, but he's not here now." He leaned back against the wall, throwing Tanaka a reprimanding look.

"Heh, yeah. I know." Tanaka tucked his hands in his pockets, shrugging sheepishly. "It's just so fun to tease her; she blushes very prettily." He grinned unrepentantly as the girl's face started burning up again.

Hitoka vainly pretended she couldn't hear them. She glanced to the clock; the Seijou guys should be there soon. Takeda-sensei got a call from the school's coach, and he nodded at something the coach said. The young teacher walked to her, his eyes practically sparkling as he told the girl that the visitors would be at the gym any minute now. Kiyoko was saying something to Daichi, and after checking that the floors were clean and there were no balls strewn around, Hitoka checked the clock again. Less than a minute.

Takeda-sensei and Kiyoko were by the school gates to escort their rival school. The boys have lined up in the middle of the court, looking sharp in their black and orange uniforms. Someone burped, and another farted, and the others snickered, Hinata's poorly-muffled chuckles reaching her ears and she smiled as well. Her nerves were eased a little by the small fiasco. Berating herself for her nervousness, she settled with gripping the clipboard closer to her chest.

She wasn't sure why she was so nervous today.

Which was a lie. She knew exactly why she was nervous today. As Kiyoko had informed when she was helping her with the chairs, the Seijou team had called for a practice match with the Karasuno team, even after losing to the boys at the semifinals. The third years were still in the club, and had figured that it was a way for the new regulars they had picked to get accustomed to matches, especially for opponents as skilled and loud as the Karasuno bunch. The retiring seniors would be playing with the new regulars to guide them, as she had heard Ukai saying before. Which meant that he would be there too. More specifically, the Seijou's Captain and setter.

Tōru Oikawa

It wasn't like Hitoka had never met the guy. He was Seijou's Captain, for God's sake! He'd played against them several times, and the last time they did in an official match, the Karasuno team won. Everyone knew about his skills as both a setter and a Captain, and about how he made Best Middle School Setter at age fourteen. It was also common knowledge that he was a ladies magnet. One of the senior coaches at Lil' Tyke had joked about how much the brown-haired teenager broke hearts left and right. The staff even made a bet on how many he had dated. All underground, of course.

However, no one knew how much she was interested in him.

She had known him to be the guy with the tears-your-arms-off serve and a pretty arrogant person before she joined the Lil' Tykes. The first few days, he had instantly recognized her as Karasuno's manager. Who wouldn't, after seeing Hinata and Kageyama flanking her during official games? The three first years were close friends, everyone could see that. At first, she had been too flustered to return his greeting, and was too busy thinking about how she would mess up on her first day on the job, Hitoka barely talked to him that day. Hinata had said that Oikawa was a scary person, and Kageyama had even warned her to 'run the hell away' if she ever bumped into him. So she couldn't help it that during her first few weeks working with the Lil' Tykes, she pretty much avoided him.

Until the day she saw him playing basketball with his friends at a park on her way back from school.

Hitoka was aware of her fixation on watching athletes duke it out on the courts. Watching Hinata and Kageyama that time when they were trying to convince her to be their second manager did that to her. She found it very artistic in the way the boys would run around the court, diving in for receives and jumping up for beautiful spikes. The sight of the boys cheering whenever they scored a point was her favorite. Camaraderie was a beautiful thing, she realized.

And as she stood fixed on the spot to the far side of the court, her mouth agape and heart pounding in her ears, Hitoka felt a dull pang in her chest as she watched how Oikawa swiftly dodged his friend who had swiped in to take the orange ball from him, and had almost effortlessly jumped to dunk the ball. He had rolled up the long sleeves of his school uniform, neck tie absent and his first two buttons popped open.

She swallowed as he had run a hand through his brown hair, made messy by the sport he'd just played, and could swear her heart stopped beating for a millisecond when she caught the droplets of sweat matting the hair at the back of his neck. "Matsun, you owe me a meat bun!"

The manner in which he was grinning and showing a 'V' sign while standing in all his sweaty glory, the orange sun filtering through the strands of his unruly brown hair was boyish and yet had an erotic quality to it.

His voice broke the spell, and she realized she was staring at a boy, and not because she was admiring the languid moves and footwork, but for a reason entirely different.

Her face had burned scarlet, not that she could see, but she was positively burning judging by the stares she got from the people around her as she all but ran home. Later that night, her mother had watched her walk about doing housework with robotic movements, an elegant brow raised.

"Hitoka, you look feverish. Are you okay?"

She had dropped her basket of laundry then. " Hogyaaa!"


Hitoka couldn't do this anymore.

Watching him like this was too much.

It was torture.

The first practice match had ended with a win for Karasuno, and now they were in the middle of the second and last practice match. As luck would have it, Oikawa was playing the match, and of course Ukai had to throw in all four first years together to play against the more experienced Oikawa. Since it was a practice, he figured they could use the chance to try and work together, all four of them, to play as a team. It was rare that all four were in the same court at the same time, and apparently it was looking a little bit shaky for them. The first year trio on the Seijou's team were also in the same predicament, since they were far too intimidated by Hinata and Kageyama's freak quick. Add in Tsukishima's height and Tanaka's loud battle yells, it was safe to assume that the game would stretch a little bit.

"Nice serve!"

Her mouth called out of habit, and she swallowed as Oikawa's eyes met hers for a split second, a ghost of a smile gracing his face before he moved across the court, easily receiving one of Tanaka's serves. She felt her face warming up at being caught staring, and quickly dropped her face to stare at her shoes.

'Gosh, stop staring at him, me!'

She lifted her head, determined to watch the play instead of how his eyes sparkled when he played. His team scored a point, and it was his turn to serve. Hitoka watched in bated breaths as he spun then ball once, twice, before he threw it up and brought the ball down into that famous tears-your-arms serve that she liked to call. They got in another point, and Kageyama's sour look as he glared at his former senpai got himself a grin from the guy.

"Rejoice, oh sweet Tobio-chan! I was going easy on you guys!"

She couldn't stop her giggles when she heard Kageyama grumbling something under his breath. Daichi appeared next to her as the game continued, and Hitoka looked up at him as he took a drink from his water bottle.

"Good job, senpai."

"Thanks. You too, Yachi."

She nodded, and before she could ask him if he needed a towel, he spoke again. "I hate to say this but the first years look kind of funny right now. I kinda get what Ukai-san wants to do, but still…"

In a rush to get the ball, Hinata had bumped his head into Tsukishima's back. Somehow he contributed a point for that, but Ukai had called for a time-out. "Geez, try to give in a little, that Hinata."

She laughed, and as she turned to look at the court, her eyes darted to Oikawa's side.

He was tipping his head back to drink his water, a hand resting at his waist. It might be her eyes tricking her, but standing a few feet away from him, brown orbs involuntarily ran over the sheen of sweat on his forehead, strands of hair sticking there. A droplet of water escaped his lips, and it seemed like every noise around her was muted as her eyes followed the droplet's movement as it slid over his bottom lip to trail slowly down towards his chin. It joined the droplets of sweat gathered at the tip of his chin and together the accumulated liquid teetered off the edge of his upturned chin, to finally drop onto his throat. She was too far gone to admonish herself and force her eyes away when the bump of his Adam's Apple bobbed as he swallowed the water he had fed himself a moment ago, and she herself swallowed as the droplet trailed over that moving bump and downwards to the hollow of his throat, disappearing altogether from her view.

She had no idea how he could make something as mundane like drinking water seem so erotic. Hitoka licked her lips, feeling her mouth dry up at the sight of such an insignificant water droplet.

She might have secretly been proud that her eyesight was impressive, but right then, she cursed whatever luck she had to have such a godsend ability. Because of her eyes, she was subjected to the realization that she most probably have a new fetish developing inside of her.

The whistle was blown to resume the match, and she nearly jumped out of her skin when he turned around to place the bottle back down and caught her looking at him again.

Why did it seemed as if he knew when she would have her eyes on him?

He had raised a brow, then a knowing smirk stretched over his lips, before he walked back into the game.

Hitoka sighed, and dropped her head to stare angrily at her shoes. How was she supposed to look at him now? Especially since the both of them go to the Lil' Tykes.

She felt a squeeze on her shoulder, and she bit back a surprised shriek as her clipboard dropped, hitting her toes in the process. She looked up at Kiyoko's confused face, a wobbly smile on her lips. She wasn't caught staring at the opponent was she? Did Kiyoko realize she was having lewd thoughts of Oikawa? Could it be that everyone could tell she was ogling at the sliver of skin exposed whenever his shirt would ride up?

"Hitoka-chan, you okay? Do you feel unwell?"

Hitoka nodded, shaky hands reaching for the clipboard that dropped earlier. She came back up, her cheeks a little pink from embarrassment. "Y-Yes. N-No, I'm just a little surprised. Ha… haha."

'Yes? No? What were you trying to say Hitoka Yachi?! Oh geez.'

A dark brow rose, before the older manager shrugged. "That's fine then. Can you fill up the bottles, and help me pass the feedback forms when you get back from the taps."

She saluted clumsily, eyes bright. Yes! A distraction! "Yesh! Gotcha!"


Seijou won the second match, because of Tanaka's overkill spike that made for a perfect homerun had it been a baseball match and a flick of Oikawa's wrist when he executed a dump shot. The first years had gaped, and Hinata's jaw had hit the ground at the unexpected sneaky attack, before he fell onto the floor face-down, moaning.

"Dammiiiiiit!"

Kageyama called him a dumbass for getting too worked up over a feint, and of course, Tsukishima had to slide in a comment that made the carrot-head rolling round on the floor writhing in embarrassment. Hitoka thought that they played a good one, despite losing.

Taking out a few towels, she jogged towards Hinata and gave him a towel, her lips pulled up into a smile.

"That was a good game, Hinata."

The carrot head pouted, but took the towel anyway, springing back up to glare daggers at a smirking Oikawa. Sighing, the manager turned to hand a towel to a grumbling Kageyama. She patted his arm, in an attempt to calm him down.

"It's okay, you guys played a good match. It was nice to watch."

The frown on the setter's forehead eased a bit, before mumbling out a "Really? You mean it?"

Hitoka grinned and gave him a thumbs up. "Yep! Definitely!" Her optimism managed to smooth out the frown on his face, and wrench out the small lifts on the corners of his lips. "Okay."

Sugawara gave a hearty slap onto his back, flashing a wide grin. "Not so bad, now is it? Go and cool yourself down over there with the others."

Kageyama nodded, and jogged to the side of the gym, joining Tanaka and the others who had just played. Sugawara gave a thumbs up to Hitoka, and watched as she grinned back, and turned around to tug at Hinata's sleeve, her cheery voice trying to lift up the shorty's spirits, and it worked. It might have been because of her words, or the fingers she kept crossed at her back, but Hinata relented from drilling holes into the back of a retreating Oikawa.

"C'mon, you guys did amazing! Look there, at the score board, you managed to score almost half of the points using your quick attacks, right? That's something to be proud of, Hinata."

Her smiles were so contagious it managed to turn a sulking Hinata into a grinning idiot. Sugawara chuckled as he spotted the reddening ears on the shorty. Hitoka was pushing at Hinata's back to coerce the boy into doing cooling down exercises and help clean up the gym when the light-haired setter saw Oikawa's face.

The brown haired guy was toweling himself down, seemingly listening to something Iwaizumi was saying. When Hitoka and Hinata walked pass them, there was a shift in Oikawa's eyes, and that was when Sugawara realized that the third-year was looking at the girl. He blinked, and wiped the perspiration over his eyelids, and watched again. Hitoka was helping Kiyoko hand out the feedback forms to the visiting team, and when she passed one to Oikawa, he didn't miss the way her cheeks blushed a faint pink and the endearment in Oikawa's brown orbs.

He breathed out an "Oh" as he observed Kageyama's former senpai.

Hitoka was walking away from the Seijou duo when Takeda-sensei called out to her, and Sugawara couldn't help but feel his cheeks warm up when he caught Oikawa watching over her retreating back. Something about the way his brown eyes softened as he watched the petite girl smiling at something Tanaka was joking about seemed very personal and intimate, and it sent shivers down the setter's spine.

A ball rolled over to her and hit the side of her shoe. Hitoka bent down to reach for the ball, and Sugawara bit his lip when he caught the small smile on Oikawa's lips when his brown eyes flicked downwards to admire her backside.

Sugawara prided himself in the fact that he could read people well, and in that instant, he could easily say that a certain Captain was interested in Karasuno's petite manager. In more ways than one.

He winced as he watched Iwaizumi noticing Oikawa rudely staring at her butt, proceeding to smack his Captain's head.


A/N: I'm done. But somehow it feels… incomplete? Well this should be a drabble, so maybe it's good enough yeah? Oh, and sorry for pervy-Yachi here. I mean, she should feel at least something when watching the guys play, right? That's normal. And someone needs to do it, right? Hihi. I'm halfway through the next chapter, and I really hope that I finish it by tomorrow. Because I'm gonna be super busy next week. *cries*

Oh, please drop a review if u can. reviews help me a lot. *wink *wink
