Kyon sat on his bed quietly reading a comic book; he had already half packed his gym bag and backpack. They were only going for a week so large bags weren't needed. There was an attached sleeping bag, map, pocket knife and emergency items in his backpack. He had also packed a torch and Leatherman just in case of emergencies.

He was only bringing what he needed and not a bunch of pointless gear. He was being practical and not an idiot like Haruhi was; bringing mostly crap and not actual tools. He took this seriously and avoided extra baggage that would only become troublesome to them during the trip.

Suddenly the doorbell went off surprising him. He recalled that he invited Koizumi over but didn't expect him for a while. It was still pretty early despite the fact that it was now sunset outside. Believe it or not the clock said it was 9:30 PM in the evening so it was still very early on.

Suddenly there were quick footsteps and Kyon's sister Ai rushed into the room "Onii-chan; someone is at the door" she chirped loudly. Her eyes were filled with curiosity and surprise. At that age all kids were surprised about everything and innocent to many things.

While Kyon was sceptical about many things; he liked to make sure his sister remained innocent and enjoyed her childhood. She was allowed to dream and fantasize for the time being; until she became older and started middle school.

He sighed heavily and put down his magazine; it seemed Itsuki was earlier than he expected. It was still early evening and the sky was red; he had thought the latter would show up when it was dark.

He made his way downstairs casually his sister following anxiously. Given how he barely ever had anyone round and spent time studying; they never really had guests. Ai had a few of her preschool friends over now and again; but he generally went out to see people. He never really brought anyone home at all; so his personal life remained a secret.

Eventually he reached the door and opened it casually. He was surprised to see Koizumi carrying everything he needed for his trip and three heavy bags full of food. He wondered how he hadn't developed any back pains on the way here.

Itsuki smiled charismatically "Hi; I'm sorry for being so late" he apologized humbly. He had tried to be as quick as possible with getting what he needed. He knew that to bother Kyon after he had been so kind to invite him would be rude. He wanted to make sure any stressful events were avoided at all costs.

Kyon said nothing; he was too surprised at the fact Itsuki was actually ready to go. He still had a few things to go over before he was ready. Yet here was Esper boy ready to go with everything. Plus given they were getting the train in the morning; he was overly advanced for the preparation.

Ai looked up at him nervously her brown eyes filled with slight worry "Kyon Onii-chan? Who is this strange Onii-chan?" she asked nervously. She had never seen this boy before; he was new to her.

Kyon patted his sister's head gently; she had never met any of his friends before. She had briefly met them at a baseball game but had never spoken to any of them. They had gone home pretty early and she was mostly at school.

"This is Itsuki; he's a friend from school. He's going to be joining us on our camping trip this week" he explained gently. He would never let his sister worry unnecessarily; but it was good for her to be cautious at her age. It meant she would always be wary of strangers and people who may do her harm.

Kyon let the lighter haired boy in and locked the door. It would take a long time of introducing his sister while avoiding any awkward questions. He just hoped Itsuki wouldn't say anything weird; then again he hoped the same for Itsuki from his sister.

Itsuki walked inside and placed his bags on the floor and stretched. They had been awfully heavy to carry all the way here. He may have had ESP abilities he used for battle; but he was still human after all.

The powers he had strained him mentally depending on how hard he used them. Due to this he was often mentally exhausted and tended to sleep a lot. Having such strong powers was very exhausting to the human carrying the gene. Being a mutant gene was not as easy as it sounded.

Ai stared up at the chestnut haired boy in adoration; he looked like a prince out of one of her books. This handsome Onii-chan would be joining them on their trip?

After stretching Itsuki knelt down to address the younger sibling "It's nice to meet you; my name is Itsuki Koizumi" he said politely smiling at her. He wanted to be polite to the youngest resident after all.

She was very cute for someone so young. She definitely had the same eye colour as her brother but lighter hair shade. When she was older boys would certainly become interested in her. However he could imagine Kyon being very protective of her.

Ai blinked quietly then looked up at her older brother "Kyon Onii-chan; how come you invited a pretty Onii-chan?" she asked curiously. He had always seemed uninterested in anything and bored as hell. He spent all his time reading comics and studying; anything to avoid people.

Kyon blushed and glared at his sister in humiliation; why was she saying such things for her age? While he did think Koizumi was walking sex in human form; he would never admit that out loud.

Itsuki laughed in amusement; it seemed his sister was of advanced intelligence for her age. Even she was able to suspect him of romantic interest in the same gender. It meant it would make it easier in the future.

"I'm Kyon's classmate and a fellow club member. He said it would be lonely with just you two so he invited me" he explained kindly. He wasn't really lying; Kyon had explained that it would be just him and his sister. He had explained it would be boring with just the two and it would be a waste for him to just stay home.

There was a long silence before Ai's ponytail perked up and she became somewhat excited. She turned to Kyon her eyes shining with adoration. She recalled how he had been very pleased with her last school report.

"Kyon Onii-chan; you really planned this trip to spoil Ai for being so well behaved at school right?!" she blurted suddenly. That was the only reason she could think of to bring one of his friends; considering how much of an introvert he was.

Kyon stiffened; what ideas was she getting into her head? He planned the trip with what money they could afford and enjoy their summer. Why did she have to jump to conclusions?

Ai's eyes sparkled; now she had 2 Onii-chan's to look after her and spoil her rotten. This was going to be the best camping trip ever! She had been really well behaved at school so they could play in the streams, go walking, watch stars and tell stories together. But now she had 2 big brothers to look after her!

Ai looked up at Kyon adamantly "Kyon Onii-chan; Ai will be on her best behaviour! She promises!" she said sternly before rushing upstairs. She would not get in the way if they wanted to be alone ;3

Kyon watched her rush upstairs quickly and slam her door. He sighed heavily; god what ideas was she thinking of? He just hoped not anything weird. She had an overactive imagination for someone so young.

Itsuki chuckled; so his sister was the complete opposite of him? How fitting indeed. It made sense that their personalities would level out. But she had definitely sniffed out their mutual attraction.

The latter saw his expression and frowned "Something funny Koizumi?" he muttered crossly. He knew he would tease him about this later on; he was a known tease in many forms.

Itsuki smiled "Sorry; your young sister is just too cute. It's hard to believe you are related by blood" he teased affectionately. His sister was so innocent and displayed the natural mentality for someone her age. How had her brother become so cold and skeptical as he grew up?

Kyon irked raising his eyebrow suspiciously "What does that mean?" he asked sternly. What was he getting at? Was it so bad that he took life seriously for a student?

Itsuki stiffened nervously; that had come out wrong. It's just that for siblings their personalities were complete opposites. He smiled nervously "Sorry that came out wrong. I meant no rudeness I assure you" he apologized awkwardly.

God how was he making himself look like such an ass? Here was his crush asking him on a personal trip and he was coming across as a jerk. He had only meant that Kyon did not act anything like his sister.

Kyon huffed crossly; for a guy Itsuki really knew how to word things. But then again given his job it was somewhat normal for him he guessed. "You can put that stuff in my room; I'll get dinner started. I hope curry is ok" he said stiffly walking into the kitchen.

Sorry that he wasn't a charming, cute and optimistic person like his sister. He was rational, thoughtful and hardworking. However he was none the less kind, caring and optimistic deep down too.

Itsuki watched the latter go into the kitchen sadness in his eyes. He had never meant to insult Kyon; he had only meant to jest. It's seemed his teasing had been taken the wrong way and Kyon was upset. He would have to find some way of making it up to him.

He looked back at his bags and picked up the ones carrying his belongings. It seemed only appropriate to put them back in Kyon's room. The other boy had said they would be sharing before the journey tomorrow.

As he made his way upstairs he was met by Ai again who was hiding at the top. Her face peaked out from the main banister head. He had a bad feeling she may have overheard their heated conversation that had just taken place.

Itsuki smiled at her kindly; she must have been worried by the tone of her brother during their discussion. "It's ok; Onii-chan just said something stupid" he reassured her kindly. He didn't want her to worry about unnecessary things.

Ai blinked then shook her head "No" she said bluntly. He hadn't said anything wrong; Kyon was just sensitive is all. But given how he was mature for his age; his emotions were potent.

Itsuki blinked; had she misheard or didn't want to believe that something was wrong? The thought brought him concern.

Ai bravely came forward slightly her expression stubborn "Onii-chan did nothing wrong. Kyon Onii-chan is stupid!" she said adamantly.

He was always so stubborn and was sensitive to a lot of things. He would never get a relationship if he kept acting like that. He needed to learn how to take a joke and understand when someone was making fun of you.

A small smile spread across his face; she really was cute. One day she would be stealing the hearts of young men everywhere. He was surprised she didn't have an admirer at preschool already. It seemed young boys at that age liked stubborn girls because they were impulsive and exciting.

He smiled warmly "Thank you for worrying Ai-chan; why don't we talk to Kyon in a bit?" he suggested. All young children felt threatened or worried when their older family members or peers fought. It was basic defence that they used to protect themselves as they were naïve to a lot of things.

Ai nodded; she needed to tell off Kyon for being stupid. Why did he never just agree or have to argue? He wasn't always right! Plus their parents had always said not to be rude to guests.

Itsuki then got up to take his stuff to Kyon's room. He found his sisters actions quote adorable and intriguing. Perhaps she was secretly playing matchmaker for her brother?
