One eye slowly creaks open, surveying his surroundings through blurry vision. Nothing out of the ordinary here. He’s in the pajamas he’s left with Alluka forever ago, curled up under an old blanket he gave her for Nanika’s birthday. It’s covered in the Matrix code, all green letters on black wool. It barely covers him from chest to knees, which explains the cold toes.

Sunlight flickers through the curtains, cheerful and bright, and Killua pulls the blanket over his face. He’ll take cold toes over being blinded by his headache.

The second sign that today is going to be an absolutely terrible day, is when a noise like a chainsaw burrowing through a marshmallow erupts from his phone buzzing on the coffee table, just barely out of reach.

Killua attempts to bury himself under the blanket. He’s not dealing with work today.

And then he remembers: He doesn’t have work. Work can’t bother him today. Not just because it’s a weekend—work never respected the sanctity of weekends, no matter that he was at least partially in charge and used to have a fancy degree hanging on his wall. He doesn’t have work anymore. Killua quit.

Which, well. That explains the hangover.

He’s still blaming his siblings.

His phone buzzes loud enough to break the sound barrier, and Killua decides, fuck it. He doesn’t have anything to lose. If it’s the-place-formerly-known-as-work, he can delete everything. If it’s Mom or Father, he can definitely delete everything. And maybe it’s a friendly person, congratulating him on giving up a job that for anyone else would have been an absolute money-making dream. He’ll delete those too.

It takes a few tries to unlock his phone, and it unfortunately involves opening his eyes, squinting against the glaring light of the screen. But once he does, he frowns. Maybe he’s seeing double. Or a hundredfold. Because he should not have this many notifications.

awwww cute, i hope u 2 find each other! the top one says. It has several hundred likes. Why is it in his notifications?

Scrolling down reveals that it’s not an anomaly.

wtf man how can you find a TWELVE YEAR OLD from FIFTEEN YEARS AGO.

Me and my mom went on a cruise around there once, it was really pretty!

this is so sweet T__T maybe this is him?

And then another hundred photos of brown-skinned men with varying degrees of shirt-wearing, all black haired and most of them buff in very appealing ways and all of them beaming at Killua.

“What the fuck,” Killua croaks as he scrolls through all of the images and messages. Maybe this is a dream. A really weird, hangover-induced dream about how little of a social life he has, that his phone is possessed by someone else’s. A warning of sorts, that he should never have installed any social media on his phone ever, not even for hookups.

The reason for all the notifications lies at the top of his own page. Just a few sentences, all-caps, with an image of an old crinkled photo of two boys on a tropical beach, grinning at the camera. Killua sees himself, white curly hair flying in all directions and pale skin sunburned and ruddy with the briny wind, happier than Killua can ever remember being. Next to him, one arm slung around his shoulders and the other holding a bucket full of seashells, is a brown-skinned boy with freckles dancing across his nose and the tops of his shoulders, brown eyes wide and laughing and black hair thick and spiked from some mix of wind and seawater and natural gravity defiance.

He didn’t know he still had this photo. It had followed him from childhood all the way through grad school, a carefully guarded keepsake hidden away from the watchful eyes of his parents and Illumi, before ending up in a box or a bag at some point in the last few years. Part of Killua thought he’d lost it in the move. He barely remembers much about being twelve, about the cruise he’d been forcibly dragged on. But he remembers…

HAVE YOU SEEN THIS BOY? yells the caption. WE WERE BEST FRIENDS FOR A WEEK WHEN I GOT DRAGGED ON A CRUISE BY MY ASSHOLE PARENTS. HE WAS 12 ON WHALE ISLAND 15 YEARS AGO. IF FOUND, DM IMMEDIATELY.

“Gon,” Killua breathes.

He gathers himself, wrapping the blanket around his head in a feeble protection against the morning, and lurches over to Alluka’s room.

He gets to bang on her door three times, confused spite winning out over his own pounding headache, before Kalluto appears out of their room, blinking blearily at Killua. “Shut up.”

Killua kicks Alluka’s door for good measure, and brandishes his phone in front of him like a weapon. “Not until you explain what the hell this is doing on the internet.”

Kalluto pales, then flushes, then pales again. “Oh. Um.”

At that, Alluka creaks her door open, guilty blue eyes far too awake for how close to noon it is. Killua kind of wants to kill her on principle alone. If he has to be hungover, so does everyone else.

“Explain,” he grinds out through his teeth.

The third and final sign that today is going to be an absolutely terrible day, is when Alluka puts on her most winning smile, the kind she uses to ward off angry customers and idiotic faux-academics on the internet. “Congratulations, Brother! I might have made you go viral.”

Killua throws his phone at her.

—————

Today’s going to be a good day, Gon decides. He’s been in the forests of East Gorteau for the better part of a month, which normally isn’t so bad. But this group has been…They’re nice enough, when Gon’s not spending half of his time explaining that, no, that species of plant does not make a good stew, and no, that species is endangered please don’t hunt them, and yes Gon is sure he doesn’t date his clients even after the hike, and no the reason the tent fell over again is because it wasn’t properly set up in the first place—

All of Aunt Mito’s complaints about tourists on Whale Island make so much more sense, now that Gon’s leading backwoods hikes.

But last night had been fun! Spinner had met the group at a pre-set campsite not far from their pickup so Gon hadn’t had to work the whole night, and he could relax with his friend over good food, more alcohol than he probably should have drunk, and not having to explain to Mrs. Yuldvin the difference between marijuana, buckeye, and poison oak again. Spinner had even taken care of the fire, although she had left him to rescue the Podomos siblings from the ruins of their tent with nothing more than a smirk and a wave. Nevertheless, Gon smiled through his headache all morning, because soon he’ll be home, and he can sleep.

Zushi is waiting in the parking lot once Gon’s done packing up the last of the gear and saying goodbye to Spinner, jeep idling while he flicks through his phone, thick eyebrows drawn together in increasing concern. He doesn’t even look up until Gon drops his pack onto the hood of the car, and he jolts so badly in surprise that he tosses his phone in the air.

“Are you okay?” Gon asks, and tries to peek at the screen.

Zushi pulls it up and away, a frantic look in his eyes. It won’t really keep Gon from seeing what’s happening, not if he wants to, but Zushi’s height is enough of a deterrent to make it hard. “You were gone way too long,” he says.

Gon leans against the hot metal of Zushi’s car. It wasn’t an unusual length for a trip, not really—this backcountry needs the length to be able to see and understand the region. Not to mention the Small Billed Swan preservation society keeping the whole place locked down except to authorized guides and trekkers. Zushi knows this. They’ve been roommates long enough that this isn’t even the longest time Gon’s been gone.

“You knew I’d be gone til today,” Gon says.

“Yeah, but…” Zushi’s eyebrows descend even further, scrunching his whole face up in worry. “You haven’t checked your phone, right?”

“No?” Even if he did have cell service, Gon never brings his own phone. He borrows Kite’s satellite phone, because it is more reliable and doesn’t need to be charged constantly.

“Okay. Well.” Zushi takes a deep breath, then another, one of Wing’s old meditation techniques. Despite his exhaustion and single-minded determination to sink into a real bed and sleep for a week, Gon feels a minor pang of worry. On breath three, he unlocks his phone and turns it towards Gon. “You’re a meme.”

On Zushi’s screen is a photo Gon can’t ever forget about. Backed by Whale Island’s sunbleached white beaches and the humid brilliant colors of summer, Gon sees himself—twelve, smiling from ear to ear, hair a mess from swimming and his shirt practically covered in sand from digging up all the seashells in his bucket. He’s got an arm around another boy, who’s caught mid-laugh so his blue eyes burn the same color as the sky, white curls even messier than Gon’s hair. They look like they’ve known each other their whole lives, like they’d still be best friends even if they haven’t seen or spoken to each other since the photo was taken.

Gon hopes Killua thinks so, too.

He cradles the phone in his hand, carefully zooming in on their faces and the errant crinkles visible through the photo. His own faded copy is in a drawer, having survived a whole trip around the world and countless apartment jumps. This one looks just as well cared for, in its own way.

“That…is you, right?” Zushi asks carefully. “Because Wing was asking, and half of Kite’s guide company is yelling about it on your social media page that you don’t even use, and now people are messaging me, and they’re saying the weirdest things, and the post is from last week, so—”

“It’s Killua,” Gon says. A smile spreads across his face, a mirror to the one he’d had when he was twelve. “That’s Killua!”

“Who?” the others ask, but Gon isn’t listening.

He spins, frantically searching his pockets for his phone. “Spinner, can you do me a favor?”

She narrows her eyes suspiciously.

Gon knew today was going to be a good day.

—————

It’s been a week, and Killua has quit all social media forever.

The steady buzz of his phone informing the apartment of his notifications is not his problem. Alluka’s the one who decided to hack into his phone and post something to his old public account, the one he mostly uses for photos of cats and complaining about terrible business precedents. He hasn’t posted much since school, and if anything, it should have simply vanished into the void of the internet.

He finds the culprit fairly quickly, and for once it’s not his sister’s moderate but dedicated video following.

“Old man, what the fuck is wrong with you?”

Leorio lounges in Alluka and Kalluto’s living room, freshly out of his scrubs and looking pleased as all hell. “I just reblogged a fun post from my friend,” he says somewhat defensively. “You were a cute kid, Killua. What happened?”

Killua feels a growl creep up his throat. “You can’t just do that,” he snaps.

“It’s not my fault the people like my well-coiffed but rugged appearance and dedication to social justice in medicine.”

“You have 500,000 followers because you made a joke post two years ago, and some authorized user reblogged it five times. It has nothing to do with your ugly mug.” If Killua squints and plugs his ears, he can even see why people think Leorio’s attractive or whatever: tan skin, lean but strong as hell, actually takes care of his hair, not to mention a damn good doctor with one of the most prestigious institutions in Yorknew who spends most of his free time running health clinics in impoverished neighborhoods. That’s all swell. But then he starts talking, and Killua has no idea where the off button is.

Leorio spreads a hand out, gesturing vaguely with the glass of iced tea that he’d helped himself to out of Alluka’s stash. “It has everything to do with my ‘ugly mug,’” he says. “Which is why I used my powers for good and spread your post. Don’t you want to find him?”

“Not like this!”

“You were not going to find him at all,” Kalluto’s quiet voice pipes up from the kitchen. They have night classes tonight, but Killua has a feeling that even if they were supposed to be attending their Yorknew Uni lectures, they would still be here making Killua’s life worse. “You’ve had that picture for years, and you did not even try to look.”

Leorio gives him a judgmental look over the tops of his stupid tiny glasses. “You haven’t?”

It would be a losing game to bury his burning face in one of the throw pillows, so Killua does his best to cross his arms over his chest and glower instead. “I…tried.”

“And?”

“I don’t even know his last name!” Killua splutters. “I didn’t have his number or where he was from, other than his mom worked on the ship. And that cruiseline went bankrupt and liquidated everything before I could get out of the house, so I couldn’t even look that up.”

Kalluto crosses over from the kitchen and perches like a sweatshirt-wearing crow on the coffee table, their blue eyes carefully neutral under straight black bangs. “Alluka and Nanika would have helped. Or even Milluki, if you had explained the situation.”

“I was eighteen, okay? I just left home, and our parents were still being…shit, themselves, I guess.” He hadn’t even considered asking for help. Then again, he’d tried the moment he could, that first summer of undergrad where he didn’t have to come home and Illumi couldn’t spend half his time breathing down the back of Killua’s neck. He had a general idea of where they’d gone, maps of islands scurried away in the closet with the old photo and a bag full of seashells Gon had given him as a going-away present.

They’d been friends for a week, in the whirlwind way that only kids can be. The cruise ship was massive, and Killua’s parents were in meetings half the time and playing nice with the other rich people on board the other half. Killua had been bored witless, and Gon was everything he couldn’t have possibly imagined: encouraging Killua to go exploring, to stealing food from the kitchens, making him help clean up the decks, playing cards with the deckhands. Sneaking off the boat to visit an island without Killua’s parents while the ship was docked, scrambling over the burning hot sands and dashing through the jungle, diving into the waves fully clothed and competing to see who could find the biggest prettiest shells. Gon’d been Killua’s first friend, his first crush, his first…a lot of firsts.

Then the cruise had ended, and Killua forgot to give Gon his phone number. His address. Anything. They’d been so swept up in being friends, being best friends, it had seemed impossible that they would never see each other again.

Does Gon even remember? Why should he, when Killua hasn’t contacted him? Would they even be friends anymore?

Maybe he hadn’t searched hard enough. But part of Killua thinks he shouldn’t have tried at all.

The phone buzzes loudly, and Killua tries not to flinch.

“Hey, Killua. It’s okay.” Leorio leans forward, hands clasped over his too-long limbs and expression gentle. “If you want me to delete it, I will. Not sure I can help with the viral part of things, except maybe go through your messages and delete the gross ones, or at least find the weirdest ones for you to laugh at later.”

“Alluka and I have been doing this already,” Kalluto says, their posture a little too protective for Killua’s raw nerves at this point. “But perhaps you have some suggestions for what to do next, Dr. Paladiknight?”

Leorio smiles sympathetically. “Don’t read the comments? That said, most of your comments have been much more positive than anything I usually post. The masses seem to be genuinely rooting for you, kid.”

“I have only had to delete a dozen lewd messages for you this morning,” Kalluto adds, not mentioning the hundred or so that Alluka took care of yesterday.

Killua’s traitorous phone buzzes again, and that’s it. Time to bury himself in a pillow. Killua flops onto the couch, narrowly missing Leorio, and does his best to burrow into the cushions. “That’s just great,” he says into the fabric.

A comforting hand rubs against his hair, messing up the curls for a moment, and Killua refuses to admit that it’s nice, that he has friends like Leorio who even bother to care. “It could be worse. You could be dealing with this while still working a soul-sucking job making more money than most of us will see in our lifetimes, in exchange for giving up all of your morals.”

Killua groans loudly. “I’m not having this conversation with you.”

“You’re gonna need to do something, Killua! And hey, I might be able to set something up with my—”

“I already told you, no.”

“But it’s what you’re good at. And you wouldn’t be fucking people over to do it.”

“No.”

“Just listen for one—”

Killua lifts his head enough to glare as murderously as he can at Leorio. It must work at least a little, because the doctor shuts up.

Meanwhile, Kalluto is scrolling through Killua’s phone, poking at the screen occasionally. In the awkward silence, their sharp gasp is loud enough to shatter a window, and they hurriedly shove the phone in the pocket of their oversized sweatshirt.

Leorio raises an eyebrow. “Everything okay?”

Kalluto squeezes their eyes shut for a moment, then carefully places the phone on the coffee table, screen pointed innocently at the ceiling. “You will want to look at this one, Brother.”

“This isn’t another erotic sandcastle is it?” he says.

Kalluto shakes their head, and Killua’s stomach lurches up his throat. Alluka has been the one excited about this whole thing. But Kalluto, as reserved as they are, is a massive romantic. The whole thing might be Alluka’s fault, but Killua knows it’s Kalluto who almost lets themselves believe it’ll work. Despite all of the false positives, the people who send messages that don’t sound right or photos that have the wrong smile.

Killua doesn’t want to hope. It can’t possibly be Gon. But his hands shake nonetheless as he unlocks his phone and finds a new message in his DMs.

It’s not from Gon.

Instead, someone with the icon of a small-billed white swan in a soft small-billed hat and a handle of @flymypretties has sent a photo of a brown-skinned man with spiky black hair absolutely covered in dirt and grime. He’s waving at the camera, a backpacking bag propped against his shoulder and the widest smile Killua has ever seen beaming straight through the screen and into his chest. Next to him and half out of frame, a tall tanned man with massive black eyebrows and a tank top showing off an impressive amount of muscle has his head in his hands. Killua feels a sharp stab of sympathy, somewhere buried beneath the racing of his heart.

look im sorry about this but this idiot can’t find his phone and we r kind of in the middle of nowhere so reception’s shit. he wants to know if you admit he found the biggest seashell on the beach, whatever that means.

For a long, long moment—seconds? minutes maybe?—Killua can do nothing but stare at the screen of his phone. Leorio and Kalluto both look at him with a mix of curiosity and worry, Kalluto starting to slowly reach for the phone.

In a completely childish protective moment, Killua grabs it against his chest, like the image will vanish if he doesn’t keep it close.

“Is it…?” Leorio asks.

Killua swallows heavily, trying to think around the roaring of the ocean in his ears. “I think so,” he says faintly.

Kalluto’s eyes widen, and they spin on their heels towards their room. “I’m calling Alluka!”

—————

“Has he responded?”

“No!”

“…what about now?”

Spinner throws her hands in the air so violently that her hat falls off. “For god’s sake, Gon, it’s been an hour, you don’t even have your phone, and you still need to go home.”

Gon huffs and pouts. They’re still in the parking lot over an hour after the rest of the trekking group has left, and all the exhaustion that had settled into Gon’s body from the tour has been turned into a jittery energy that keeps trying to leak out from under his skin. He wants to go home immediately and dig out his copy of the photo, rub out the old fingerprints he and Aunt Mito have left on it over the years. He wants to find his phone and message Killua directly. He wants to wait right here until Killua responds, no matter how long it takes.

He knows it’s childish, to be this selfish. Spinner has work to do, work that she already put on hold to help with the last day of the tour. Kite probably will want to know what’s happening, or at least why his lead guide and his chief guide organizer have been stuck in a parking lot. And Gon can practically feel Zushi’s obsessive scrolling through social media, frantically trying to navigate Gon’s feeds without actually having access.

Gon needs to find his phone.

“Spinner, what if—”

It’s not that Spinner’s a large woman. Out of the three people standing in the parking lot, Zushi’s far and away the strongest, even if he is about as threatening as a large, muscular teddy bear. And Gon has only packed on weight and muscle over his years of backpacking around the wilderness, no matter that he’s not super tall. But Spinner goes for longer, harder treks on her own than anyone but Kite, and she packs in her own climbing gear on top of that, so when she tosses Gon into the back of Zushi’s jeep, he flies.

“Zushi,” she says in a low exhausted snarl, and he jumps right off the hood of his car. Gon probably would have felt bad for him, if everything wasn’t spinning. “If you do not take your roommate home, I am not responsible for the consequences.”

“What if you hear back?” Gon groans around the aches in his side.

Spinner rolls her eyes, and Gon knows she’s just tired. “I’ll let you know.”

“But what if my phone’s gone? What will I do if someone stole it, or if I can’t—”

“I’ll call you go home already,” she says, and slams the door shut on his face.

For a long moment, the only sound is Spinner storming away, boots thudding heavily in the dirt until her car door slams.

The jeep shifts slightly as Zushi quietly lowers himself into the driver’s seat and puts the key into the ignition. Gon wants to tell him to follow Spinner, so she can yell out the window as soon as Killua gets back to her. But Zushi looks about ready to bolt. So Gon slumps back in the seat, the rumble of tires crunching through gravel making his already jittery nerves shake.

A small voice that sounds a lot like Kite tells Gon that it’s better to wait, that it will be easier to have a conversation and determine if this really is Killua after a rest and a shower.

Gon doesn’t want that, though. He wants…

It’s been a long time since he was on Whale Island. Longer still since he saw Killua. That doesn’t mean he stopped thinking about either of them, during the quiet moments out under the stars. They’re part of him, like his lungs are part of him—essential and irreplaceable, buried so far inside that removing them would change him irrevocably.

What is Killua like now? Is Gon just as important to him as he is to Gon? He has to be. Right?

They make it home without saying anything else. Gon floats in and out between bone-deep weariness and electric sparks of nervous joy, and Zushi flinches every time Gon jolts himself from one to the other.

“Hey, are you…I mean, maybe not okay, but.”

Gon lifts his chin up sharply at the sound of his roommate’s voice, and notices the familiar apartment complex in front of him. Oh, they’re home. “I’m good,” he says, and grins.

“Sure,” Zushi says like he doesn’t believe Gon.

A dubious silence stretches out between them as they gather the rest of the gear, dropping it in a heap on the sidewalk. “You were kids, though,” Zushi finally says.

Gon shrugs and slams the door shut hard enough to make the vehicle rattle. “I didn’t forget. So I don’t think Killua would, either.”

Zushi’s eyebrows wrinkle on each other, like they can’t decide whether to go up or down and settle on some combination of the two. “What if he did?”

“He didn’t,” Gon says, more sure of that than anything else in his life.

Zushi’s eyebrows dance again, but he doesn’t say anything else.

Between Gon’s camping gear and Zushi’s leftover practice pads, it takes longer than Gon’s excitement can take to get everything settled enough to look for his phone. Well, Gon would have liked to look for his phone, but Zushi makes a pointed look at the shower. There are only so many places the phone could be in the whole apartment, after all.

Gon’s just drying off when Zushi knocks on the door. “I found it, but it’s dead,” he says, voice muffled.

“Then charge it!” Gon shouts. After a moment, he adds, quieter and less snappishly, “Please?”

A faint laugh echoes through the apartment.

By the time Gon can make himself a very early dinner of whatever he could grab out of the cabinets without thinking, the phone is charged enough to turn on. Sure enough, there are a wide variety of messages, mostly from Kite’s groupchat asking about the viral post. A few are from former hikers, people who Gon liked enough to share contact info, offering to see if they can get in touch. There are even a few—okay, how did they get ahold of his old social media page? It’s practically defunct, since Gon’s never had a phone capable of more than the most basic apps. And those are…

It’s flattering in a way, but Gon’s not really into that. Or them.

Zushi catches sight of the grimace, and takes one look over Gon’s shoulder before turning beet red.

By the time he’s gone through and deleted the vast majority of what had been filling up his phone, there’s still no message from Spinner, and nothing at all from Killua. Gon sighs and lies his head down on the table with a heavy thunk.

The other chair scrapes heavily along the tiles as Zushi sits, a mug of coffee in his hands. “What will you do? When he messages you, I mean.”

When, not if, an unexpected certainty coming from Zushi. Gon has the best friends in the world. “Talk to him,” Gon says. “It’s only been fifteen years, right? We promised we’d be friends forever.”

“A lot changes in fifteen years,” Zushi says.

“Not that.”

“Then why didn’t you look for him?”

Gon frowns. It had taken a long, long time, but Aunt Mito managed to track down the cruise captain the last time they were in port, tracing through old charters until the right names came up. But when she’d called them up, she’d been met with stonewall after stonewall, pleasant-sounding voices insisting in no uncertain terms that she would never speak with a member of Killua’s family, let alone let her son speak to his friend. By the time Gon was old enough to look himself, he found nothing but a mansion full of people whose eyes matched Killua’s in everything except for his warmth, who refused to even acknowledge Gon’s presence except to throw him out.

That had been years ago. It’s not that Gon stopped looking. Not exactly.

“I did, but I—” Gon starts to say, but his phone buzzes violently against the table, and they both jump out of their chairs.

“Is it—?” Zushi asks, breath in his throat.

It’s a message from Spinner. you owe me big time, kid, she says, followed by a phone number.

Gon rips his phone off the cable, a wide smile spreading across his face. “It is,” he says, and dials Killua.

—————

bzz bzz—

bzz bzz—

bzz b—

“H-hello?”

“Killua! Hi!”

“…Gon? Is that—It’s really…?”

“Killua, it’s you, I thought I’d never—”

“I did find the biggest seashell, and you know it.”

A breath, sharp and astonished. “The blue and white one, with green lines.”

“I found it, and I gave it to you.”

“I still have it.”

A snort of amusement, slightly damp. “I know. You promised you’d keep it.”

“I did. And I promised—”

“That we’d be friends forever.”

A laugh, delighted and teary at the same time. “I knew you remembered.”

“I did promise you that I would.”

“Yeah?”

“Yeah.”
