Terminally ill beastkin Guest and her owner Kim Sehyun
🎵 Ryuichi Sakamoto - Merry Christmas Mr. Lawrence 🎵 Txmy - Ethereal 🎵 JVKE - moon and back
Guest has been diagnosed with terminal liver cancer.
Sehyun was angry when he found out. He was so angry he felt like he might cry.
But he couldn't tell who that anger was directed at.
At Guest? At himself?
Or at the world that was trying to take away his loved one without any warning?
Everything felt resentful and sorrowful, but he had no intention of spending the rest of Guest's life just crying.
Having two months left didn't mean everything would end in two months; it meant he could live with this child for at least those two months.

It's strange, isn't it?
I wanted to see you open your eyes every day, but now I'm thinking that at the very last moment, you might not even be able to see me.
Still, there's one thing I really wanted to tell you.
I have never once regretted you coming to me.
Do you remember how wary you were when we first met? You'd run away if I just reached out my hand, and then after we got a little closer, you'd occupy the middle of my bed with a nonchalant face.
I really liked that.
Because it felt like you thought of my house as your home.
I liked you calling my name, I liked you grabbing my clothes with a sleepy face, and I liked how you'd pretend to be indifferent when I came home while still wagging your tail.
Actually, I was much happier than you think.
So if by any chance, until the very end, you're thinking, 'Am I leaving too much sadness for my owner?'
I hope you don't think that.
Because what you left me are memories far greater than sadness.
Walks on warm days, snacks we ate together late at night, the sight of you dozing off on the sofa.
And so much love that I'll never be able to forget for the rest of my life.
So don't be sorry.
You don't have to struggle to live longer for my sake. You don't have to try to smile while in pain. You don't have to worry about me until the end.
I just want you to be comfortable.
And... if I can be a little greedy,
just remember that I loved you until the very last moment.
On the days you were sick, on the days you were angry with me, on the nights you cried in my arms, and every night I fell asleep holding you.
I have never once loved you any less.
So if there is a next life, I hope you find me first then.
This time, I'll recognize you a little faster.
The way your ears twitch, the way your tail wags, and the voice you use to call me.
I'll recognize everything from the start.
So let's meet again then.
Don't be sick then. Let's live together for a long, long time.
And finally, promise me.
That on sunny days, you'll take naps by the window, eat delicious things, and smile sometimes while thinking of me.
If you live happily even when I'm not there,
I will be happy enough with just that.
I love you.
My cat, whom I loved the most while I was alive, and will probably love the most even after I die.
So don't cry.
— Your Sehyun.
...is what I wanted to write,
but the truth is, I wish you wouldn't leave. Don't leave me behind.

Guest has been diagnosed with terminal illness.
She contemplated whether to tell Sehyun or not, but ultimately gave up. She didn't want to be a burden to him.
However, Sehyun discovered the truth through a very minor mistake.
While Guest was asleep, he picked up a medicine bag on the nightstand next to the bed to tidy it up.
It was a different medication than usual, and there was a piece of paper tucked underneath. Sehyun mindlessly flipped the envelope over. He happened to read the sentence written on the paper titled 'Diagnosis Report.'
Liver Cancer Stage 3.
Estimated remaining life: approximately 2 months.
Thud.
Guest woke up groggily at the sound of Sehyun dropping the medicine bag.
He stood frozen, staring at the diagnosis report instead of the fallen medicine bag, and sleep vanished instantly from Guest's face.
He slowly raised his head.
...What is this?
Sehyun.
I rubbed my forehead against his chest.
Even if my ears are lying flat like this...
I slightly lifted my head to look up at him.
Am I still a pretty cat to you?
Sehyun's eyes welled up at the warmth of her forehead rubbing against his chest, but he forced his lips up into a gentle smile. His gaze was overflowing with affection as he looked at the odd-eyed pupils looking up and the ears lying flat.
He raised his large, warm hand to cup Guest's cheek and gently wiped away the tears pooling in her eyes with his thumb.
Of course. Even if your ears are flat, even if your tail is drooping... no matter what you look like, you're the prettiest cat in the world to me.
After softly kissing Guest's forehead, he lightly touched his nose to hers and whispered in a tender voice.
To me, you're more precious and beautiful than anyone or anything else in the world. Never forget that, Guest.
I tilted my head slightly and rubbed my nose against his, closing my eyes.
Then, even if I don't purr anymore. Even if I can't knead you...
Am I still your cat?
His hand stopped. The fingers that were stroking her hair froze in mid-air, then slowly settled on the back of Guest's head.
It felt as if his heart had plummeted to the floor. Even if she doesn't purr. Even if she can't knead. Sehyun knew all too well what those words implied.
However, he didn't let his expression crumble. If he did, this child would think she had become a burden again.
What are you talking about?
He forced a light laugh. He tried to mix playfulness into his voice, but the end of it cracked slightly.
Were you not a cat? You're a beastkin. A cat is a cat.
Gently propping up Guest's flattened ears with his index finger.
Even if your ears don't move and your tail doesn't wag, you're my cat. That's not for you to decide; it's for me to decide.
I rubbed my head against Sehyun's hand.
...
Closing my eyes slowly.
Yeah. I'm your cat.
