Gon's POV

Gon walks into the kitchen, Hisoka had left him breakfast on the table with a little note saying he'd be out for the day. As much as Hisoka liked to believe he was the uncaring older sibling, Hisoka cared a hell of a lot. Gon starts eating and takes the opportunity to call Killua.

"Hey!" Gon smiles into the phone, happy Killua had picked up.

"Hey, Gon, what's up?" Killua's voice is so soothing to hear. Gon relaxes a little, continuing to eat.

"I was just wondering if you wanted to go out today... Like... A date?" Gon asks, realizing he could take the opportunity to go on a date. They had been out, but they never really called it a date.

"Open up," Killua says, confusing Gon before he hears a knock on the door. Gon scampers over and opens the front door. "I think a date would be pretty cool," Killua says both into the phone and at Gon before hanging up.

"Okay!" Gon says excitedly, although, Gon hadn't exactly planned past that. Where would they go? Or do?

"How about lunch," Killua offers. "And a movie?"

"How'd you know I-"

"I know you Gon," Killua chuckles, walking into the apartment, plopping on the couch. His white hair sticks up in all directions, a natural messy look that really suited him. Gon walks over and sits next to him. Killua is really beautiful... Killua looks over and raises an eyebrow. "Aren't you a little close?"

Gon realizes he had leaned in, close to Killua's face. "Maybe..." Gon murmurs, glancing at Killua's lips. They hadn't kissed yet but maybe now...

They jump away from each other when the door is slammed open by Hisoka. Gon watches as he walks in frantically.

"Killua! Oh thank god you're here, do you know where your brother is?" Hisoka asks, he looked genuinely worried, all composure gone.

"I thought he went out with Machi to some fashion show?" Killua replies, keeping his composure.

"Yes, yes, and they were supposed to be back from that, and Machi did come back. Without Illumi. She doesn't know where he is either. He's been gone the whole night Killua, he won't answer his phone." Hisoka hisses, turning around and hitting the wall. Killua and Gon glance at each other. Why would Hisoka get so worked up?

"Hey, Hisoka, Illumi is a full grown man, he can take care of himself," Gon says slowly.

Killua snorts. "I'm sure there's nothing to worry about, he probably got distracted by some shop windows on his way home and got an inspiration rush or something and went somewhere to draw. He disappears sometimes to work alone."

"For a whole day?" Hisoka presses.

"Hisoka seriously, why care about him so much? He's my brother. He's fine." Killua waves it off.

Hisoka's golden eyes, however, are still full of concern and Gon frowns, he had been under the impression Hisoka and Illumi aren't getting along. Maybe he is wrong? Gon walks over and pats Hisoka's back.

"I'm sure Illumi will call back okay? And soon." Gon smiles widely at Hisoka, trying to cheer him up.

Hisoka nods a little and walks towards the balcony where Gon watches as he grips the edge, his knuckles turning white from grabbing it so hard.

"Let's head out now, leave Hisoka to himself," Killua suggests.

"Yeah..." Gon nods, Hisoka definitely needs a moment alone, but Gon doesn't want him worrying so much either. But Illumi has to be fine, everything about the man made him seem untouchable, there's no way anything could have happened.

Gon hesitantly takes Killua's hand as they walk into town together. The two weren't often very affectionate, Gon had been hoping to change that. He really liked Killua, really really liked Killua... Yeah, they were meant for each other, but Gon felt so strongly toward Killua that if anything were to happen to him, Gon wouldn't...

"Killua... I think Hisoka and Illumi are soulmates," Gon realizes.

"Those two!? You have to be kidding..." Killua trails off. "Wait, that makes total sense."

"Yeah, but then why don't they just love each other?"

"Cause they're both stubborn dumbasses," Killua replies before pulling Gon into a restaurant. "C'mon, they have such good food here."

***
The two boys laugh together as they make their way to the top of Killua's hotel building. They had been sneaking to the roof for a long time. It is... their place. Where the two could go to be alone. Peaceful, quiet, only the soft city noises below them, a comforting sound.

They sit down on the roof, making some small talk before silencing. Killua begins running his fingers over Gon's collarbone, where his tattoos were. Gon had lightning bolts dancing across his collarbones to his shoulders. It never made sense until he saw how happy Killua became at the storms that passed through. Killua would often sit at the window, or even outside, to watch the lightning. The lightning always made his eyes light up... Gon loved watching him when he was like that. Like lightning was apart of him in another life...

Killua looks up at him and smiles. "I love your tattoo," he says softly and Gon leans in, kissing Killua softly. The feeling had just overcome him.

When he pulls away, Killua's face is a bright red and Gon laughs at him.

"You- You can't just do that!" Killua sputters.

"Do what?" Gon plants little kisses all over his face. "That?"

"Gon!" Killua kisses him, full force, placing his hands on Gon's cheeks. Gon smiles into it, kissing him back. They pull away and Gon smiles softly at Killua.

"Was it okay?"

"Of course it was, stupid!" Killua rustles his hair and once again they're laughing together on the roof.
