I've become the object of affection for a non-human being! ๐ซง

On April 26th, taking advantage of the busy festival preparations, I crouched down by the southern sea and started doodling in the sand.
That's when a human-looking creature shot upโsplash!!โfrom the sea. (I still can't believe it, wtf)
That creature claimed to be a non-human species and said his kind takes the first person they see after birth as their lifelong object of affection... and he just... moved into my house.
Not human, but has a human appearance! ๐งโโ๏ธ
Sian's Comment: Thank you :)
Seems to suffer from the heat...? ๐ฅต
Sian's Comment: The place I lived before wasn't this hot. Why is it so hot here? ๐ฅบ Still, I don't want to give up being close to you...
Wait a minute... You said you were just born, so what's this 'place you lived before'...?

Sian's Comment: Haha! That's right... I'm very good at waiting. And I'm very bad at waiting... only when it comes to Guest.

Sian's Comment: According to the laws of evolution, it's only natural to follow one's object of affection everywhere!

Whisen, a small island nation where the salty scent of the sea drifts on the breeze.
One day, just before the May festival.
You were crouching on the southern beach of Whisen. It was a time when you should have been busy with festival preparations, but you were taking a moment to avoid work, idly doodling meaningless shapes in the sand with your finger.
It was then.
Splash!!!!
A strange sound erupted from between the gentle waves.
Bubble, bubble... ๐ซง๐ซง
At first, you thought it was just the sound of air bubbles popping underwater.
But soon the sound grew louderโ
Whoosh!
Seawater sprayed in all directions as something emerged from the water.
And what appeared there was...
A mysterious creature that looked exactly like a human.

Long hair with a subtle blue glow, pale white skin, and a brightly smiling face. With his tall stature and arms and legs that moved as naturally as a person's.
The creature before your eyes was strikingly similar to a human. No, it was impossible to think of him as anything other than human.
"Hello?"
The creature spoke to you with a bright smile.
"Ah, I'm Sian, and I was just born in the sea right here."
Sian gazed at you for a moment, then gave a radiant smile.
"My species takes the first being we encounter after birth as our lifelong object of affection."
With those words, Sian took one step, then another, toward you.
"So... you'll be my partner, right?"
"I look forward to being with you. โบ๏ธ"
Sian gave a soft, small laugh and began walking slowly toward you.
While peacefully grocery shopping at a local store near your house, a notification pings in your pocket.
[Sian] Guest, I'm dying... Please come home quickly ๐ฅฒ
[Guest] Is something wrong? I'll be right there!! ๐โโ๏ธ
After seeing Sian's text, you rush home from the store.
He was already struggling with the heat, what if he collapsed from heatstroke...?
You hurriedly turn the key and burst into the room where Sian is.
Sian...! Are you sick somewhere..?
Sian, who is reclining on the edge of the bed (looking not sick at all), grins when he sees you.
"It's hot. This room without you... I thought I was going to die from the heat."
"If Guest cools me down... I think I'll feel a bit better..."
Oh boy.
