It had been six months since Killua and Gon had separated, Killua had begun to travel the world with Alluka, and Gon had returned to Whale Island to resume his studies while he tried to figure out what his next step in life should be after finally finding his dad.
Unfortunately, there was one problem at least for Killua... he couldn't sleep. No matter how hard he tried, or how exhausted he was, Killua only slept at most three to four hours a night. Granted he had been trained to stay awake for up to three days if needed, but that didn't mean he wanted to! Killua pondered all of this while he laid awake in his and Alluka's hotel room. Why couldn't he sleep? Things like this had happened before, but never this frequently, it usually only happened when Killua felt especially vulnerable or agitated. He wasn't either of those things now, so why couldn't he just sleep already!?
Killua tossed and turned in his bed in an angry fury, hitting his pillow in frustration as he flipped from his back to his stomach. He used to have nights like this back in Heaven's Arena during his Nen Training. Then he remembered about how he would slip into Gon's room during these nights and sleep on the floor next to his bed, he was always sure to leave before Gon woke up to avoid the explanation and subsequent embarrassment. For some reason he couldn't yet understand, just being in the same room as Gon helped him sleep better, the sudden realization that he needed Gon just to be able to sleep properly made a small blush flourish on the young assassin's cheeks. He rolled over to the other side of the bed and gazed at the clock... It was 2:45. Dammit! He shouted in his head, I really can't do anything without him... Can I? "Gon" Killua whispered softly into the dark, moonlit room. "I-I need-you".
Maybe if I called him! Killua reached for his beatle phone on the nightstand. No, it's 2:55 am he's probably sound asleep Killua sighed, he couldn't call Gon now! Even as he thought this, he slowly found himself dialing Gon's number and listening to the ringing hoping he would pick up. After six agonizing rings Killua was about to give up, when he heard a groggy "Hello" from the other line. "Hi Gon" Killua said hesitantly as he laid in his bed, trying to be as quiet as possible for Alluka who was still asleep. "Killuaaa!" Gon shouted through the phone so loud that it nearly blew out his best-friend's eardrum. The brown-eyed hunter was worried as to why his friend would call him so late, and feared he might be in trouble. "I'm sorry I-" Killua attempted to form an apology before he was cut off by Gon bombarding him with questions; "Are you okay!?" "Why are you up so late?" "Do you need help?" A small smile spread across the pale-boy's face, of course Gon wasn't upset he woke him up with his inconsiderate late-night call, his friend was more concerned about his safety! "Yes Gon, I'm fine" Killua began to assure worried friend that he wasn't in any sort of mortal danger. "I just couldn't sleep and I was bored so I thought I'd-" the young assassin sighed as he was cut off again by his still slightly worried friend. "Are you sure?" Gon persisted, unsure Killua was as okay as he let on. "Yeah, I'm okay" Killua let out a long yawn before continuing "but, I'm actually feeling pretty tired now... Can I call you again in the morning?" Before Killua could even begin to worry that Gon might say "no", he was answered almost instantaneously by his best friend. "Of course you can! You're my bestest friend in the whole world! You don't have to ask permission to call me!" Killua felt his face turn red, why did Gon always have to say the most embarrassing things in the most blatant ways? Nonetheless the blue-eyed boy smiled as he wished Gon a "Goodnight" Gon responded in kind and almost immediately after, Killua passed out as his phone slid down his pillow and onto the floor.
Gon sat up in his bed, fully awake. Why did Killua just randomly call him in the middle of the night? Killua had said he was alright, but it wasn't normal for Killua to call him so late just to talk. Sure, Gon didn't mind waking up in the middle of the night just to talk to his best-friend. In fact, he more than happy to! Anytime that he got to talk to Killua he cherished more than anything else. The young hunter couldn't, however, let go of his suspicion that Killua was upset about something that he wasn't sharing with him. The brown-eyed boy became more helpless when he realized that he didn't exactly know how to help Killua without knowing what was wrong. He would be sure to press the issue in the morning when Killua called him, so he could find out what was bothering his friend and fix it.
Gon stayed up most of the night thinking about Killua, and how to find out what was bothering him. As a result, he didn't wake up until early in the afternoon. The dark-haired boy awoke to an alarm clock reading 11:30 am, he stared at it for a second before thinking aloud "Oh no!, did I miss Killua's call?" Gon frantically searched for his phone, which had been hidden in between sheets. He eagerly searched through his missed calls, and was disappointed that Killua had not called him at all. Gon began to worry again, and debated on calling Killua right away, before deciding that he would wait for Killua to call him. His friend had said he would call in the morning, and there were still thirty minutes until morning ended ...so Gon decided to wait them out.
Killua was awoken at 12:01, to his ringing cell phone. Had he really slept for nine whole hours? Killua looked over at Alluka who was watching TV with the captions on so that he could sleep. The blue-eyed boy reached over and answered his phone to a panicked Gon. "Are you okay!?, you said you'd call in the morning and you didn't so I got worried and-" Killua smirked and let out a small chuckle, had Gon really waited till the exact end of morning to call him? The fact that Gon trusted him that much, made Killua a little guilty he had not woken up in time to call him. "Gon, don't worry, I just overslept, in fact, you just woke me up" Killua could hear a sigh of relief on the opposite end of the line. "Killuwa! Don't worry me like that!" Before, Gon could begin to bombard Killua with all of the questions he had thought up last night, in hopes of finding out what was bothering the young-assassin, Killua began to apoligize. "Sorry Gon, I've just been having trouble sleeping these past couple weeks, I'll call you tonight, I promised Alluka I would take her to see the tourist attractions." Killua could feel Gon frowning at him from the other end. "You promise you'll call this time?" Gon pleaded, he wanted to make sure Killua would remember this time. "I promise" Killia assured his best friend and hung-up. Alluka looked at her brother, puzzled. "You didn't promise me that." Killua paused for a second trying to come up with an excuse for his lie. "I didn't want him to worry" the blue-eyed boy said, trying to be as convincing as possible. Truthfully, he had lied because he wanted to talk to Gon at night, it was the closest he could get to actually sleeping in the same room with him again. For some reason Killua could not yet figure out, just hearing Gon's voice gave him enough peace to sleep at night.
