First of all: This is my very first fanfiction or story ever. It's just a try and I would appreciate your comments (:
As I said, I did not pay attention to real relationship and age.

Kazuma's fingers jerked the keyboard uneasily. Once again he spent the day in front of the computer. The music that came from his headphones could almost be heard in the next room, which is why he did not notice that someone was entering the room. Only when a hand came to rest on his shoulder did he startle.
>> Uahh !! What the - << Startled, he looked into the sneering brown eyes of his counterpart, tearing the headphones off his head.
>> Hello, Kazuma. << A young man with dark brown, curly hair, a dark blue shirt with the top buttons undone and faded jeans sat opposite him, smiling, who looked the boy up and down, followed his arm over the keyboard to the screen. >> Aha. <<, he said as he looked at it and at the same time the grip tightened on Kazuma's shoulder. >> Aren't you a little too young for that? << Again a smile. Kazuma wondered if his interest was just a pretense, he couldn't define it.
"No." he replied coolly. >> I turned sixteen a few weeks ago, in case you've forgotten, UNCLE! And please let go of my shoulder, you are preventing me from typing. <<
As always, thought Wabisuke, that calm, indifferent tone, though he might be really annoyed, but who could say that? And you can't keep your fingers off the keyboard, not even to brush your deep brown, straight hair back from your face. With a smile he said, shaking his head: >> Don't you think that you spend a little too much time in front of the computer? This is not good for boys your age. Be careful not to get addicted. <<
>> boys my age? << Now he was getting really angry. >> Maybe boys my age shouldn't have an uncle who suddenly disappears abroad. How long have you been in america Five years? You just left me here with all the crazy people And now, just before grandma's ninetieth birthday, you come back and pretend you've been there every summer. Do the others even know that you are back? They'll tell you something else. You will be happy if Grandma recognizes you at all. MEN your age change a lot, you know. << Kazuma glared at Wabisuke, indicating that it was really time to let go of his shoulder and leave.
>> But you recognized me immediately. << Still smiling, Wabisuke got up and walked calmly to the door. He's still quick-witted, he thought as he left. >> And Kazuma, you should have your hair cut, you can't see your beautiful eyes at all. <<
What was that?Kazuma thought confused. Suddenly, after five years, his uncle appeared in his room. Just like that, without notice. Just the way he disappeared. He had just turned twenty at the time and fled the family as Kazuma had always explained. What annoyed him most was that his uncle hadn't even sent a message telling him where he lived or whether he was still alive at all. For five years he had always told himself that his uncle was dead just to forget him. But inwardly he hadn't been able to let go of him, had always hoped to run into him at some point. How often had he looked around when he was out on the streets of Ueda? And now he was there. All by himself.
Kazuma was so madly angry. He grabbed his headphones, which he had carelessly dropped on the floor earlier, put them on with a bitter expression and turned the music up a bit. He wanted to keep typing, but with the best will in the world he couldn't concentrate. Desperate, he hit the keyboard, dropped his head, and noticed that his eyes had filled with tears.
