KilluGon
Killua Zoldyck did not believe in soulmates.
Well, that's not true; it was mostly due to his family's influence that he did not believe in them. Once upon a time ago, when Killua had been very little, he had heard gossip and rumors about soulmates and their bonding, and had once asked his dad if he had one.
"You should forget about having a soulmate, Killua," He said. "In our line of work, they would only be a distraction, nothing more. Don't waste your time on such nonsense."
Since then, he had never asked again, knowing half of his family would say. His mom would mostly likely be thrilled for him to have a soulmate - if only according to her standards. He suspects she wanted his soulmate to be some upstanding citizen, much like the Zoldyck family, if not more so. That being said, Killua hated the idea of soulmates and have since stopped believing in them.
It wasn't until after he escaped his household for the first time, did he remember the idea of soulmates.
Supposedly, a soulmate is a person whom you are completely compatible with either romantic, friendship, or just someone you trust. They were suppose to be the other half of you, whatever that suppose to mean, and typically on the same wavelength as you. Meeting your soulmate varies from person to person, but typically, it all leads to the same thing: your heart knows.
After hearing that, Killua snorted and officially began his non-belief in soulmates. Even if his family had wanted him to believe, to his own ears, it sounded stupid. A person who's on the same wavelength as him? Does that mean Killua's soulmate, if he had one, is a murderer too? If so, he thinks he could live without ever meeting them. Maybe, for this one instance, his family is right; he would be wasting his time in trying to find his soulmate.
Kind of funny how, without trying, Killua did in fact meet his soulmate - and he's nothing like Killua thought he would be.
Gon Freecs. The boy with a sunshine smile, openly trusted everything without a spare thought, was not afraid to speak his mind, and Killua's very first friend.
The first thing that stood out to Killua was the fact that they were around the same age, and yet, there was a difference between the two. It had made the assassin curious, and without knowing it, felt compelled to follow him - even stopping his skateboarding so they could run walk together through the halls of the first exam. He hadn't known it at the time, but meeting Gon had caused a spark within Killua to go off, surprised by the fact that Gon could keep up with him, despite living a completely normal life compared to Killua's. They had made it a run to see who can get to the top first, had their first pillow fight thanks to Leorio's blunder, and as the exam went on, Gon kept surprising Killua at every turn and Killua found himself growing comfortable around Gon more. By the time the exams ended, Killua could say that Gon was his very first, very best friend.
Gon had already decided that Killua was his best friend, the jerk.
What had surprised Killua, though, was when the assassin failed the exam the first time and Gon went after him. He had been so sure that the idiot wouldn't follow him to his home, to get him back, yet he did. From what Leorio had told him, he had been so angry with his older brother, that he nearly shattered his arm, and from that one comment, that one little thing, Killua felt his heart skip a beat. A tingling sensation had washed over him, and he heard the name Gon echo inside his mind, his heart happy and singing as much as it could. He hadn't understood it, at the time; why he was so embarrassed when Gon did things that seemed out of the normal for him (Gon was never normal, he had to remind himself), why his heart did funny things whenever Gon was mentioned or around. Why it'd hurt when Gon had decided to take Palm out on a date, why he was worried when Gon got attached to Kite as quick as he did, and after everything they went through, when they had split apart, when they went their separate ways after the Ants thing, his entire heart felt shattered and destroyed.
It was then, when Alluka brought it up, that he realized....
Gon was his soulmate.
"Big brother really loved Gon, huh?" She asked, looking at him. "You....do you think he's your soulmate mom and dad talked about?"
He wanted to deny it, wanted to say that he had no soulmate, that soulmates didn't exist, but....
Why was it when you left, that my heart kept wailing out for you even though I know you wouldn't return, not without finding your dad?
Knowing that brought a whole new set of tears, and Killua....Killua felt so alone, after Gon had left. His heart felt empty, still crying out for the that one person, but after moping for a good month and half since the split, Killua had to move on. He still needed to keep both him and his sister safe, so long as Illumi was out there, hunting for them. It had been painful, but Killua couldn't keep thinking about Gon - even if they promised to keep in contact. He has to live for Alluka now.
At least, that had been the plan before he and Gon met up again, accidentally.
The bronze kid from Whale Island had grown, just an inch taller than Killua, his spiky black hair still as wild as ever and his eyes - his beautiful, deep, golden brown eyes - still maintain the look of innocence, but....
There's also a bit of maturity in them too.
"Killua!" He gasped, running straight towards the white haired assassin and picked him up and swung him around with such ease, Killua was mortified.
"Put me down you idiot!" He said, blushing even when Gon began to laugh. The hunter did as he was told, beaming at Killua.
"Killua! I'm so happy to see you again!" He exclaimed, hugging Killua. Once more, Killua felt his heart leap into his throat and. And.
Not again.
"It's good to see you too..." Killua chuckled, trying to pry himself away from Gon, but Gon didn't budge. If anything, his hold grew tighter. "Gon."
"I'm sorry," Gon whispered, causing Killua to pause. "For a lot of things. I'm sorry I never listen to you. I'm sorry that I hurt you. It was never my intent. Forgive me?"
Killua sighed. "I've forgiven you a long time ago, idiot. Don't worry about it."
The grip didn't loosen, and Killua could feel his patience wearing thin. "Gon, if you don't-"
"You're still hurt." Gon interrupted. Killua didn't say anything. "I know because I can feel it. In my heart." At that, Killua felt himself tense without meaning to. "I didn't understand it when we were younger. I mean, I knew of the stories Aunt Mito told me, and I have always wondered if I would ever get one of my own, and I did. I still do, that is, if you would let me. Killua," That's when Gon pulled back and looked into his eyes, serious and determined. "I'm your soulmate. And I know I don't deserve to be. But I would really like to make it up to you, if that's okay. Because I think, no, I know I do," There was a tiny, sad, smile on his face that Killua wanted to wipe off. "I love you, Killua Zoldyck. And I would do anything to make you see that I could be a good soulmate for you."
Killua was pretty sure his face was no longer pale, given how heated it felt.
"I-Idiot," He stuttered. "S-saying such embarrassing things," He turned his head away. "Okay, fine. We can be soulmates, or whatever."
"No, I'm going to prove that I'm a good soulmate," Gon emphasis, getting a startled laugh from Killua. "Aunt Mito told me you can have more than one soulmate. I....It's selfish, I know, but you were always my Killua. Now you're my soulmate. I'm not very good at sharing."
That caused Killua to smile.
"Neither am I."
After that, it was almost like the split never happened - Gon and Killua were attached to the hip once more, going any and everywhere they could, learning new things, fighting with each other again. Gon would easily slide his hand against his, tighten his hold, and this time, occasionally ask what Killua is thinking, taking a more direct approach to the assassin than he did when they were younger. Eventually, the idea of soul-bonding came up, and Killua had been hesitated.
"Are you sure you want to? If this fails, then one or both of us dies."
"I..." The words don't care were on the tip of his tongue, but Gon didn't say it. Not now, not with this. "If you die, then I will follow."
Killua felt his face flush, bristling.
"Idiot! Don't say things like that!"
They continued to argue about it before eventually, Gon had convinced Killua to soul-bond. Surprisingly, it well; Gon and Killua's soul taken well against each other like a fish to water. Killua could feel everything Gon was feeling, and he shivered when he found himself wrapped around his love. It didn't feel like his family's love, cold and overbearing, but warm and soft, like honey. It made him smile.
"Killua~" He heard Gon speak, even though Gon was in the bathroom of the hotel room they were staying at currently. "What are you thinking about?"
"You. Us, I guess." He thought back. He could hear Gon hum a little.
"Hey, Killua, want to join me in the shower?" Killua felt his face heat up.
"W-What? Where did that-?"
"PLEASE, Killua? We use to do it all the time when we were kids!"
"That's because we were kids, Gon! We're older now!"
"Yeah...older." There was a hidden message that was not lost on Killua, and he could feel the blush on his face deepen. He bit his lip.
"Fine...be there in a sec."
Maybe Killua regret not believing in soulmates, if it meant he could be this happy.
