Chapter Text
„Iwa-chan! Iwa-chaaaan!”
Iwaizumi ignored the bright voice that was coming from under his window and continued focusing on his homework. His friend, however, didn’t let him.
“Come on, Iwa-chan! I know you are in your room and you can hear me!”
“I know but I don’t care” Mumbled Iwaizumi to the walls of his empty room. After a couple of seconds Oikawa’s shouting stopped, but he heard his mother’s cheerful voice and knew that she let him in. Just a few seconds and Oikawa would be knocking forcefully on his door. He sighed loudly. Just a little more. 3… 2… 1…
Knock. Knock.
“Iwa-chaaan! I’m coming in!”
Iwaizumi turned around on his chair and faced Oikawa, who was standing at the door. He was smiling so bright almost all his shiny teeth were visible. He was obviously holding something behind his back, and Iwaizumi was already afraid of it.
“What do you want now, Oikawa? I have to study!”
“I knooow, but it’s important!”
“Wait, don’t you have to study, too? Don’t tell me you finished it already!”
Oikawa laughed cheerfully and stepped inside Iwaizumi’s room. He ignored Iwaizumi’s question.
“Iwa-chan, I have an idea!”
“No.” Iwaizumi instantly turned back to his desk. He had enough of Oikawa’s ideas for a lifetime, he was sure about it, even though he was only eleven.
“Come on! It’s a brilliant one!”
Iwaizumi sighed and turned back. Oikawa was standing in front of him, hiding his hands behind his back. It was clearly visible that he was really excited about something, so Iwaizumi decided to give him a chance. Not that he could ever succeeded with telling the other boy no.
“What is it?”
Oikawa’s smile widened and he finally showed him what he was hiding. When Iwaizumi realized what they were exactly, he raised his eyebrows questioningly. He expected a lot of crazy things, but…
“Envelops?!”
Oikawa nodded enthusiastically.
“Fourteen envelops! Seven for me, and seven for you!”
“But… why? Do you want to write to someone?”
Oikawa nodded again, and handed Iwaizumi seven envelops.
“I will write to you, and you will write to me!” He said cheerfully. Iwaizumi tilted his head.
“Write to you? Why would I write to you when I see you every day?”
“No-no-no, you won’t be writing for me-me, but for the present-me!”
Iwaizumi raised his eyebrows a little higher.
“What?”
“All right, let me explain! We write letters to each other, but we don’t read them. We do this every year on… let’s see… this day would be good, and we will do this for seven years, including this one. And when we are eighteen, we will open them and read them!”
Iwaizumi stayed quiet for a minute. Then he silently turned back to his desk and to his barely started homework.
“This is stupid.” He mumbled, and Oikawa began whining behind him.
“Come oooon, Iwa-chan! Please, I really want to do this!”
“But why?” Asked Iwaizumi, who still didn’t turn back to face his friend.
Oikawa didn’t answer him. Iwaizumi turned back to him and saw that the usually energetic and happy boy was not smiling at all.
“Fine! Fine!!!” Iwaizumi shouted. He stood up and stepped closer to his friend, who looked up at his eyes. “It’s only one letter per year, so it won’t be that much of a bother, anyway.”
Oikawa began smiling again and Iwaizumi exhaled in relief.
“But what are we supposed to write?” He asked while they both sat down on the floor. Iwaizumi got them some hardcover books to write on.
“Anything! You can tell me anything in them, that’s why it will be exciting when we open them.”
“When we are both eighteen, right?”
Oikawa nodded and began writing.
“Seven years later when we are both eighteen and still best friends.”
