I heaved a sigh as I stared down at my piano scores. The song was finally done, and all that's left to do is to play it in front of everyone else and hopefully, she'll listen to it too. I stood up from the stool and then turned to look aside. There was a picture of her, Jieun, or as I used to call her, IU. I still remember why she chose to be called 'IU'. According to her, it meant "I and you" symbolizing that we can become one through music. She was not wrong though. We could, in fact, become one in music.

"Jonghyun oppa ~ " IU said as soon as she saw me walking into the music room. This is where we always came during recess. She was sitting on a couch with her guitar in hand. "I'm almost done with the song. Want to listen to it?" She asked with the most beautiful smile I've ever seen.

"Hm, I'm not so sure if I have the time for that..." I teased. IU narrowed her eyes and puffed her cheeks, not finding it even a bit amusing. I rolled my eyes and shook my head. "Of course I want to listen to you play, dork."

She didn't seem to be bothered by the 'nickname' as she happily pulled up her guitar and placed it on her laps. "I'll warn you first, oppa, this is the best song you'll ever hear that you'll find the other songs to be boring and not special in the least."

I remained still and didn't say anything as I waited for her to start playing. Soon her fingers moved over the guitar's strings and her music filled the entire room. It was soft yet somehow strong at the same time. I don't know if it was just me, but her song filled my mind with so many thoughts and memories of us together.

As soon as I blinked, I was brought back to reality. I was filled with so much happiness a few seconds ago and I found myself smiling, but now that I'm not with IU anymore, I can't help but to feel empty and lonely once again.

"Hey Jonghyun, you ready? Our guests have arrived and they're waiting for you." Key said as he had walked into my room without knocking the door.

I took a deep breath and nodded. "Yeah, I'll be there in a second."

"Yah! You ain't getting one more second. Let's go!" Key said as he walked in and pulled me out of the room.

When I got outside, I was suddenly in the middle of a crowd. I didn't pay attention to anything that was around me, though I tried. After a few minutes later, Key finally announced that I had written a song and would be playing it tonight. Everyone cheered and clapped their hands, and in a blink of an eye, I was already on a platform stage with a piano.

'I hope you'll listen to this, Jieun, and that we'll become one once again.' I thought and closed my eyes as I allowed my fingers to flow swiftly across the ivory. The room was filled with a composition so complex and so luxuriant it was hard to believe that only one pair of hands played. My own music pulled me into my mind and allowed me to be with her once again.

"I can't believe I've got a contract!" Jieun gasped and then covered with her hand. I grinned at her and pulled her into a hug. She deserved it. Suddenly, Jieun burst out into tears in my arms. I caressed her hair and hummed a song for her to calm down. "I wouldn't have made it if it wasn't because of you." She commented as she pulled away from me. "Now I can't believe I'll be leaving and you won't."

I shook my head and smiled - this smile I had right now was a special one, since only she could manage to make me smile with such love and happiness. "Don't. You deserve this more than anyone else. Believe me, Jieun."

She bit her lower lip, not wanting to cry anymore, as she pulled me into another hug. "Promise me that no matter what happens, we'll always stay friends." She whispered.

I felt a knot form in my throat. Why? Why should we always and only stay friends?

"Jieun, sweetie, we must go now." Her mother called out.                        

She heaved a sigh and pulled away from me once again. "I have to go now, oppa. Promise me, please." I didn't want to promise to stay friends with her because I wanted more than just her friendship, but she was leaving already and I'm not sure when will I ever see her again. She moved away from me, and I couldn't help but to panic, so before she could leave, I promised her. She smiled happily and nodded. "We'll see each other soon."

If only I knew, I wouldn't have let her go.

I watched as Jieun walked farther and farther away from me with her mother. When she was out of my sight I heaved a sigh. I turned around and walked on the opposite direction. I was a happy guy, even though Jieun had left without knowing my feelings towards her, but at least she was pursuing her dream and she'll be happy.

The next couple of months I dedicated my time for my music. Most of the songs I wrote didn't seem good enough for me. My inspiration, Jieun, was gone. She was still in America, signing contracts and playing her music.

Fortunately, a few days later, I got an email from Jieun saying that she would be back to Seoul soon and she wanted to see me. I immediately wrote back. Of course I wanted to see her too!

That night, I've planned everything. I wanted it to be perfect, since I was finally going to tell her how I felt. I asked for Onew to go pick Jieun up at the airport, while I would be waiting at the beach, where we would be having dinner under the bright moon. I was so nervous about it, yet so sure and happy.

The rhythm of my music changed. It was now more gentle and slow, and in a way, it filled the room with sadness and anxiety. My fingers seemed to have a mind of their own, as they moved through the piano keys.

My mind was still somewhere else, far from here.

"JONGHYUN!" Onew shouted at the top of his lungs as he ran towards me. I turned around, surprised to see him like this and Jieun nowhere. "Jonghyun, you have to come with me. Jieun was involved in an accident!"

Those simple words, that simple sentence was able to make my world come crushing down. I opened my eyes again. I took a deep breath and bit my lower lip, not wanting to cry right now. I still remember that day very clearly. My heart broke into pieces when the doctor came out to talk to us about Jieun, and I'm not sure it has healed.

I looked down at the piano and realized that my song was soon coming to an end. One year ago, in a day just like this, I lost my Jieun.

Everyone was wearing black, just like I was. I took a last glance at the bouquet of flowers I've brought. Without thinking, I raised my head, closed my eyes, and allowed the wind embrace me. No matter how many times I've wished for it to be different; no matter how many times I've wanted to escape from reality; no matter how many times I've close my eyes, hoping to see her again when I opened them, it just doesn't happen.

I closed my eyes again and I swore I felt a hand touch mine. It wasn't any hand. I knew this feeling, this touch, it could only belong to my beloved Jieun. I was afraid that if I opened my eyes again, I wouldn't feel her presence anymore.

I've dreamed, a thousand times, about how that night should've been like. And I knew that I would rewrite it again; our story will not end.

Jieun sitting across from me, enjoying the view. The moon, shining bright up in the sky, would be our only light.

"I love you, Jieun, I've always had." I should've said, and she should've smiled - that perfect, breath-taking, beautiful smile of hers.

When my song came to an end, everyone clapped their hands, forcing me to open my eyes. I immediately looked down at my right hand, but there was nothing and no one was near me. In that moment, I couldn't help but smile, knowing very well that Jieun was here with me today. This song is our story and it hasn't ended yet. Soon, one day, I'll meet her again and we'll finally be together.

It's been a year already, IU. You don't know how much I've missed you. I hope you've liked the song, baby, you inspired every single note in it. I tell our story through my music and soon, one day, we'll be able to write it together. Saranghae.
