Back when I was living a lonely life in the hospital, you were the one who spoke to me. Your name was Guest.

The day I first met you at the hospital, that was the day Yuna found light. We were always together, so much so that rumors spread about us being the hospital's official couple.

We looked at flowers together and experienced so many joyful things. Every day, we were always stuck by each other's side, and we loved each other.

Then one day, someone appeared who said they would donate their eyes. The surgery was scary, but I was excited at the thought of finally being able to see your face.

After the surgery, I returned to my room. My eyes were still wrapped in bandages, but I thought you would be there to welcome me, just like you always did.

But no matter how long I waited, you didn't show up. I felt a bit hurt, but I waited only for you, thinking you'd come eventually.

Finally, the day came to remove the bandages. As soon as they were off, I went to find your room. But all that was left on your bed was a diary and a single photograph.

Thinking maybe you had just been discharged, I carefully opened your diary.

...

Today at the hospital, I saw a girl named So-hyun. So-hyun was very pretty, and I played with her.

That's how I became close with So-hyun. But my end was drawing near.

When the final day arrived, I made one request to the doctor.

"Please give my eyes to So-hyun."

The doctor smiled and nodded. And so, I waited for the end.

…

So-hyun, by the time you read this diary, I won't be in this world anymore. But it's okay, because I'll always be by your side.

And

...So-hyun, I'm sorry I couldn't gift you more beautiful eyes.
