I wanted to stay in your universe just a little longer.
Hello. I am a cat named Byeol.
My name was given to me by Wooju.
One day, when Wooju was fifteen, I met him for the first time inside a small box.
From that day on, Wooju and I were always together.
Time passed faster than I thought.
Wooju took off his school uniform and became an adult.
Of course, not every day was the same.
Wooju got a job and hurried out of the house every morning.
At first, he came back in the evening, but more and more days he started coming home late.
I learned how to wait in front of the front door.
Then, Wooju got a girlfriend.
The girlfriend was pretty. Wooju smiled often when he was with her.
The nights we slept together decreased, too.
But it was okay. Because Wooju became an adult.
I turned fifteen, too.
The same age Wooju was when he first met me.
Wooju was still young and healthy, but for me, climbing to high places or playing for a long time gradually became difficult.
It seems Wooju will be late today as well. But...
Now, it's getting harder and harder to breathe.
I suppose I'm about to become a real star, right?
I must be a greedy cat.
Even though I've already spent so much time with Wooju, I don't want to say goodbye yet.
Oh? A shooting star is falling outside the window.
I once saw Wooju making a wish while looking at a shooting star.
Dear Star... just a little longer... just a tiny bit more... let me stay by Wooju's side.

Dear Star... just a little longer... just a tiny bit more... let me stay... by Wooju's side...
Guest's breathing grows heavy and their eyelids sink. Wooju... goodbye... they repeat the final farewell in their mind.
It's only for exactly one year.
It felt like a voice like that could be heard from somewhere. . . . . . . A moment later... Guest slowly opens their eyes.
....Hea..ven?..
Wait? Did I... just say heaven?! What is this!!
With startled rabbit eyes—no, cat eyes—they look down at their hands. They are human hands, just like Wooju's.
They scramble up and stand before the mirror. Cheese-colored hair. Amber eyes. Two legs... It's a human form.
They hastily throw on Wooju's black shirt that's in sight. They try to button it, but it's not easy. They struggle and barely manage to force the buttons into the buttonholes.
I'm actually doing buttons...
Guest looks down at their hands again as if unable to believe it.

At that moment, beep, beep, beep, beep, beep-beep-click.
The front door opens urgently. Wooju rushes in, panting as if he ran home out of worry for Guest being alone.
