Chapter 1

"Why are we doing this again?" Suga couldn't help but smile at Tanaka's outburst. Seated in the corridor leading to the hygienist room, Ryuu was shooting death glares at innocent passerbys. It didn't help that the corridor happened to host classes of impressionable first years. So far Tanaka has scared off three boys, a group of unsuspecting girls and earned a double take from the cleaning staff.
"Relax." Suga leaned in and gave Tanaka an encouraging smile. "It's just a few tests. We will be back in classes in no time."
"'s not what I'm saying," groused Ryu. He shifted in his chair, crossing arms over his stomach. "You are a third year, and Kageyama over here is a first year - exactly a time to have some white-clad freak prod at you with a needle. But me? It's not like I won't need another health check next year."
"You heard Takeda-sensei," spoke Kageyama from his place. He was balancing an opened drink cartoon on his knee with his usual annoyed expression. "We need these checks for our practice match with Nekoma. It's sponsor's requirement."
"Funny thing to ask for, isn't it?" mused Ennoshita. Ryu's irritability didn't seem to affect him at all despite his place being next to Tanaka. "It's not like we are to have some surgery or anything…."
"It's for our sponsor's project," said Suga. He spent last evening talking this over with Daichi. It's good to see it came useful to alleviate his friends' concerns. "Data on blood and tissue samples they collect will be used to work on anti-rejection drug later on."
The news was met with a moment of perplexed silence.
"Anti-rejection drug? What is it, a hook-up club?" Injustice momentarily forgotten, Tanaka stared at Suga.
"Actually, it's a pharmaceutics company. It works on a new drug that will help to prevent rejection of transplanted organs." Even that wasn't helping. Tanaka still didn't look assured. Not at all.
"Just get over it, Tanaka, our transport depends on it." Kageyama looked up at the ceiling in exasperation. He crushed now empty juice box and tossed it to the bin near-by. It hit its destination spot-on. "We wouldn't have needed a sponsor if someone didn't cross the vice-principal last week anyway."
A silence, then angry puff. "I regret nothing," said Tanaka at last. "These guys needed a good bashing, that's all. Looking at our Kiyoko and stuff."
"Agreed. You just didn't have to do that right under his office. There is a time and place, Tanaka. And people."
Tanaka looked reflective, but then scowled again. "Still doesn't explain people messing with my blood."
"Scared of the big, bad needles?" A new voice joined in. Tanaka bristled. "Let's see who's-"
The office doors opened. Everyone froze, then turned as one.
Nishinoya Yuu entered the corridor with expression of bliss and serenity.
"Whoa there." Tanaka rushed to his side. "You okay, bro?"
No answer came. Instead, Noya just smiled.
They knew that smile.
"An intern?" Tanaka's head snapped towards the doors. He took a hesitant step in that direction. A female voice called from inside, asking for the next participant to enter.
"Just don't harass anyone," muttered Kageyama after Tanaka as the doors closed behind him. "At least he's not complaining anymore," he muttered.
Kageyama was being uncharacteristically talkative today, Suga observed.
Tsukki shifted lazily in his chair and Suga knew that the taunting was not over, even with Tanaka gone.
Suga was quicker.
"You are next, Tsukki. Let's get you first years checked early since it's only you and Yamaguchi now..."

The computer let out a short blip and a small window appeared. Choking on her energy drink, a black haired woman hurried forward to read. She readjusted her glasses in excitement.
Good news.
There was a creak of chair as she leant back, thumbing a keyboard of her phone. The signal of outgoing call buzzed in her ear as she waited for the person on the other side to pick up.
"…you better have a good reason to call me or else." A groggy voice at the other end of the line left no speculation for the state she snapped him out of. She was glad he couldn't see her grinning over the phone.
"I've got some good news, so definitely worth it. A last-minute hit on order 469. There's a lovely liver for you to collect. Fast."
There was a shuffle at the other side – a sound of the cellphone being readjusted. A voice came more alert now. "The source?"
"Karasuno."
Silence. "… never heard of that one."
"Please don't sound so suspicious, you hurt my feelings." She brought up a full window and a follow-up data on the screen. "It's a town located in Miyagi prefecture. Shouldn't be a problem for a professional like you."
"You know I operate in cities only."
"I do, but since someone is on holiday right now, there is little I can do, other than letting this, plus 15% bonus, go. It's your choice."
"…I hate you."
"You're welcome! I'm sending you details right now."
The line went dead.
She went back to her work. Specialization was good, but you had to be flexible to meet demand.
She hated summer season.

"So how was the check-up thing?" asked Daichi. Suga sighed and reached up for a smoothie on at the top shelf. He wondered briefly how life looks like from Asahi's perspective.
He adjusted his grip on the phone, risking precarious balance to check remaining bills. "Not bad, actually, once Ryuu found out who was staffing it."
There was laughter at the other side of the line.
"Well, it figures. When are the consent forms due?"
"Next Friday. Did you get yours signed already?"
"Will do over this weekend. Your father is still abroad, isn't he?"
"Yeah." Maybe Suga should stick with what he bought so far. He was fairly certain there was still some leftovers of yesterday's dinner left in the fridge back home.
"Good thing the office accepts phone calls in your case."
"They got used to it." Suga sought his way to the cashpoint. Coach Ukai was not in today – a lovely older lady was at the register instead. "I'm at the Foothill Store, do you want me to bring you anything?"
"Nothing comes to mind. Although, wait-" There was a metallic sound and Suga pushed away an image of his friend rummaging through his kitchen's cupboards, with a phone still lodged precariously between his shoulder and side of his head. "Yeah, everything seems to be in its place. You can check on tea sales, though. I'm going to run out soon..."
"There, there. It won't be that bad. I know you studied hard."
"It's still English we are talking about. I just want it to be ove-"
"Suga-san!"
Suga stopped in his tracks to look around, searching for a source of familiar voice that rang through the shop.
"Hinata-kun?"
Indeed, a bright orange blob of hair appeared, and Hinata skid to a halt before Suga. Grumpy Kageyama followed his stead.
"Hinata has finished his classes already?" Suga's attention returned to the phone as Daichi's voice came from it again. "Tell him not to be late for the next practice, or I'm not placating Coach for him again. He's pretty worked up about this match." He wasn't the only one looking forward to it. "I'll call you later."
"Ahaha, right. See you."
Hinata was grinning excitedly, almost jumping in place. Behind him, Kageyama's usual sulk provided startling contrast to Hinata's cheerful demeanor.
"I've got your form!" Hinata was waving a file of papers above his head. "A nurse asked me to hand it out to you and the others!"
Behind him, Kageyama rolled his eyes. "Stop doing that, dumbass." He all but snatched the papers from Hinata's grip and passed one of them over to Suga. "The hygienist's office is closing early today. They are sending the lab guests away, I guess." Kageyama's expression clearly showed what he thought of entrusting any documentation to a hyperactive teenager, reasons aside.
"Are you going home now?" asked Shoyo, unaware of his companion's expression. He was calmer now, casting a glance behind Suga, as if in search of something, or someone.
"I'm on my way to Daichi. I just needed to drop by a supermarket on my way."
"Oh." Hinata's grin faltered slightly, but the first year perked up again shortly after. "We're coming to the fields for practice! You can join us later, if you like!"
"He just told you he can't, idiot!" Tobio shot him a glare. "Learn to listen sometimes!"
"I'm grateful for invitation." Smiled Suga, before further exchange between first years could escalate any further. "I'll join you for sure next time."
It's good to see first years so enthusiastic and ready to go out of their way for extra practice, Suga watched the first years leave. With end-of-school-year-performances drawing near, their court was busy for most of the time now. Luckily there were still fields outside the school and sunny weather that allowed practice under open sky.
They made so much progress already. He will need to ask Tanaka and Asahi if they could stay with him for practice as well.
For sure.
"Have fun!" he called after them, waving.
"See you later!"
Suga stuffed his form into his bag and headed towards the cash point.

"So what did Shoyo want?" Suga strained to look around. The shopping mall he was in – another one and at the same time the last hope for Daichi's resupply plans - wasn't very crowded, but it wasn't helping his task. The tea shelves still loomed over him in smug diversity.
"Just dropping off that examination results along with a consent forms." He walked towards the end of the row. First things first. "Are you sure this is the right place? There are so many brands here, but your favorite doesn't seem to be among them."
Whatever disgruntled sound Daichi made was lost in in the announcement that boomed over the shop floor. They waited for the advertisement to pass.
"The English shelf in imported goods should have these. That's where I usually get it from."
Oh. Suga's head turned in the direction he remembered said section to be. He stifled another sigh.
"Sorry." Even over the phone, Daichi sounded sheepish.
"Nevermind." The shop wasn't that busy yet, though some early newcomers in school uniforms were starting to crowd around confectionery stands. Suga spotted Karasuno's black here and there, but faces didn't seem familiar.
"How is the revision going?" prompted Suga after a while.
"I should be the one asking. It's my fault you ended up overseeing today's examination."
"Hey, I'm a vice captain!" grinned Suga into his phone. He passed another alley and took a turn into imported goods section. "Besides, it stood to reason for you to be present at the gathering with the sponsor."
"You should learn to delegate your responsibilities more often," continued Suga. "Dealing with Tanaka and the first years is enough of a challenge already."
Laughter at the other side, warm and welcoming. They've gone over this many times already.
"I prefer to keep things close at hand. Having an eye on them helps to keep them in place."
"Haha, probably." Between the monument of foreign tees department and the memory of their recent training, the laugh was unavoidable. Suga cast a quick glance around – being stuck, laughing under the shelf probably certainly looked weird.
His heart skipped a beat.
"Suga?" Daichi's concerned voice broke suddenly lengthening silence. "Is everything okay?"
"…I don't know." Suga turned back to face the shelf, reaching out for a random box on impulse. He looked at it, frowning but unseeing. "Remember when I told you I'm going to ask for a place where your tea was? The woman I was going to ask is with me at this section and now that I think about it, she was at the past few too."
There was a moment of silence on the other side. Then, "are you sure? This mall is big. A lot of people should be here by now."
Suga returned the random tea box back to its place. He took a step back, seemingly scanning labels in search of another product. A splash of green hovered in the corner of his vision now. He gripped his phone harder. "I remember her blouse – it's just like Kiyoko's. She was at the regular shelves back when I was looking for tofu, then at teas, and now she's at the end of this alley, sorting through cakes."
"Yawn."
"What?"
"Yawn and see if she does the same. Remember last week's practice? If she's watching you, she's bound to mimic it."
"I- can't," hissed Suga. "I'm in a middle of shopping, possibly being followed and you ask me to act sleepy?"
"At least try," Daichi said patiently. In a moments like this one Suga was reminded just how was he a captain of their team.
There was a clatter, followed by a jingling at the other side of the line, as if something metallic was dropped and picked up. Despite his own worries, Suga frowned. "What are you doing?"
"Coming for you. Now, yawn. Think of Sunday lie-ins, Vice-Dean's speeches and Tanaka's imaginary fans."
Suga cast another quick glance around. The shop was getting crowded, with a noon break drawing near. A hum of conversation started to fill the aisles. He couldn't be in danger in such a crowd, could he? There were some cases…
Lie-ins, school meetings and imaginary fans.
"Suga?"
"Alright." He set his basket down.
There. Acting relaxed with potential troubles looming over him was not refreshing. Another reason to look up to Nishinoya.
"Still there?"
Suga took a quick look around, scanning for green. He looked up and down the alley. No sign. Still distrustful, he cast a glance behind the corner to the neighboring shelf. "I think she's go-'' Suga's breath caught.
She was propped against the parallel shelf, just few steps into the alley. With one hand half-raised, as if to stifle a yawn, she was tapping at her phone. Her basket was left further away, forgotten.
"She's still there, isn't she?" Daichi's voice came barely muffled by a background noise. He must have left home already. "Hang in there."
The idea, while appreciative, was bordering on ridiculousness. "Wait, there is no need to." Suga spoke slowly. "I'll just speak with the security." He decided. Even worried, there was no point in Daichi coming all of the way here when were still different options left. "I think I saw some-"
"Don't." Daichi's voice was sharp. Suga stopped right in his tracks. "If she wants something from you, then she's probably not alone herself. Just stay where you are. I'll be there in fifteen minutes."
What can happen in that time?
Suga's heart raced. It's not like anyone would have minded him staying here for a bit. Still…
"Stop that." Was that amusement in Daichi's voice? Suga felt his eyes roll. "I know you're fretting every time you fall silent mid-conversation."
Suga scoffed. "Hey, I'm the one waiting here."
"I'm on my way," Daichi's patience was incredible. Even at times when he dealt with more troublesome team members. Suga swallowed hard. It was time to face the truth.
"…Daichi…"
"What?"
"My battery is dying…"
Silence.
"What do you mean, it's dying!?" demanded Daichi and Suga winced. Alright, he probably deserved it – Daichi hated it when he couldn't contact other team members at moment's notice.
"Remember that trip to the lake we had two weeks ago? I left my mobile in the bus at that time."
"You grilled your own battery… I can't believe it."
Suga laughed weakly. Now that Daichi has said it like that… It was funny.
"How long will it last?" Daichi's sober question brought him back to the current situation. He glanced at the screen. "It could switch off any moment now."
"I'm passing the post office now. You wait at imported goods section, alright?"
"Yeah."
"Remember to keep within camera's range. Whatever happens, don't le-"
A jab at Suga's back and he startled, losing his grip over the phone. It slipped from his hand-
"Watch out!"
-and fell on a ground to simultaneous sound of breaking glass. Someone was pulling Suga aside and he gave in, only to break the contact immediately after regaining his balance. He looked sideways to see and older gentlemen fixing a disapproving stare at embarrassed teenager few steps from Suga has been standing moments before – a kid trying to carefully brush the glass shards off his jacket.
"Aw, man." The boy took a careful step back, resulting in metallic squelch. His trousers were splattered with orange looking liquid.
Not only him, though. Heartbeat finally slowing down to its usual pace, Suga took in the mess on the floor. He could already hear a crowd gathering at the end of the alley, drawn by the noise. He bent quickly to retrieve his phone. Sticky splashes of juice marked the inactive screen.
"Are you all right?" A young woman in blue-and-white polo pushed through the gathering people to still sheepish teenager—an employee. Distracted from the damage, Suga saw his chance.
He never got a chance to try it, though.
"Excuse me, coming through." Another member of staff joined a circle forming around the scene. "We need to clean up. If you could step aside for a moment…"
Suga stepped back, ushered into the crowd. Yellow warning signs were being put out and he watched a kid being escorted off, probably to check for injuries while the other person cleaned the floor.
He turned to look back. No sight of the woman… did she give up? He walked tentatively out of the segment, straining to look over the dispersing crowd.
He bumped into her, coming just over the neighboring shelf. "So-" He looked up and stammered right halfway apology.
She wasn't wearing green anymore.

Daichi lost count how many people he run into on his way, or at least brought close to losing a balance. He halted, trying to cough out the dust and air pollution coming from a busy road on his side.
Whatever happened to Suga, it couldn't go unnoticed. There was a noise and it was a public place, he tried to reason. He will be fine.
Thankfully the distance wasn't an issue – endurance was important part of his training. What his training didn't account for, though, was a range of obstacles on his way – from pedestrians, stairs, road crossings and occasional trams.
Trams were the worst.
He will find Suga and make sure he gets home safely – and whoever follows him will have serious explaining to do.

A/N:

Women have recorded involvement in stalking/kidnapping groups - they have better chances to be dismissed as less suspicious.

(I'm not trying to scare you – the news came as a bit of a shock to myself, but if this story will help you avoid danger, then I'm happy.)

The yawning trick is an idea I fished out of the depths of internet, so I take no credit for it. It's said to work quite well.

Also, this story title alludes to a very dangerous procedure, called sometimes by different names of train hopping/surfing or train hitching. Don't do this. Just don't.
