The wind howled softly across the summit of Mount Eltaris, brushing through the long grass that danced under the fading sunlight.
The sky was painted in gold and violet — a calm evening in a world that had long forgotten noise.
At the highest point of the mountain, two young men sat side by side on a jagged rock overlooking an endless horizon.
Below them stretched forests, rivers, and plains — a breathtaking view that would've made anyone speechless.
But to them, it was already too familiar.
Three years.
Three long, silent years in a world where no one else seemed to exist.
"Oi, Kaito."
The voice came from the boy with white hair that shimmered like silver silk, his crimson eyes catching the evening glow.
He was tall, calm, and carried an air that could silence a battlefield.
A black coat draped over his shoulders, marked with faint silver runes that pulsed whenever the wind touched them.
This was Jin Suho, known only to his friend as the idiot who kills too many monsters for fun.
Kaito, sitting beside him, tilted his head lazily, a half-smile curling on his lips.
His black hair danced with the wind, a few golden highlights glinting near the ends.
His amber-yellow eyes glowed faintly — like living embers that never went out.
He wore a red-lined cloak over light armor, the kind that looked both functional and stylish.
If Suho was the moon, calm and silent, Kaito was the sun — loud, bright, and impossible to ignore.
Suho spoke again, his tone calm yet carrying a hint of nostalgia.
"It's been three years since we got summoned to this world."
Kaito leaned back, letting the wind blow against his cloak.
"Yeah… three years already, huh?
We've come a long way. You're Level 10 in both magic and swordsmanship now — that's insane.
Meanwhile, I'm still stuck at Level 8 Mage. I never thought you'd actually hit Level 10."
Suho chuckled, brushing a strand of white hair from his eyes.
"Neither did I.
On the first day, I was practically obsessed with hunting monsters.
Looking back, I was insane."
Kaito burst out laughing.
"Oh, trust me, I remember that day. You went after a wyvern with nothing but a broken sword and some half-baked fire spell!"
Suho smirked, a bit embarrassed.
"And yet, I killed it."
"Yeah," Kaito said, laughing even harder, "after it nearly burned your pants off!"
Both of them laughed.
Their voices echoed across the silent mountain, as if the world itself had missed the sound of laughter.
After a moment of quiet, Suho's expression softened.
He leaned forward, resting his arms on his knees as he stared at the fading sun.
"Three years… don't you think it's about time we go find other people?"
"I mean, it's just been us — for so long. Three years without meeting another human feels… weird."
Kaito's smile faded into a thoughtful grin.
"Yeah. I've been thinking the same thing.
Sitting on this mountain, killing monsters every day — it's fun, but kinda boring now.
I want to meet new people.
Maybe even… get a cute girlfriend, y'know? Especially now that I look this good."
He ran his hand through his hair dramatically, as if posing for an invisible crowd.
Suho laughed, shaking his head.
"You're unbelievable. But yeah… I get that. I want a girlfriend too."
Then, he paused for a second, as if something random just popped into his head.
"And maybe… a little sister."
Kaito turned to him with a dumbfounded look.
"A sister? Why the hell do you want a sister?"
Suho shrugged, his crimson eyes reflecting the sunset.
"I don't know. It just… feels right? Maybe I just want someone to annoy."
"You're insane," Kaito said, laughing. "Completely insane."
"You say that like it's new," Suho replied, smiling faintly.
They laughed again, this time softer — a warm, quiet laugh that carried years of shared memories.
The air between them felt heavy but peaceful.
They didn't need to say it out loud — they both knew that their lives here had been simple but lonely.
A world without humans, without villages or guilds.
Just endless forests, ruins, and monsters.
They had built a home out of the mountain — a wooden cabin reinforced with magic, filled with trophies from their hunts.
Every night, they'd cook whatever monster meat they caught, argue about whose spell was cooler, and talk until dawn.
It wasn't a bad life.
But it wasn't complete either.
Kaito exhaled deeply, watching his breath fade into the cool air.
"You know, Suho… sometimes I forget we're not from this world.
It feels like home already."
Suho smiled faintly, gazing at the vast horizon.
"Yeah. It's strange. I used to dream about going back…
But now, I just want to see what else this world hides."
"Maybe we'll find people," Kaito said.
"Or maybe the world really did end, and we're the last idiots alive."
Suho chuckled softly.
"Then I guess we'll just keep being the last idiots alive."
The sun dipped lower, setting the clouds ablaze in orange and red.
Their auras — Suho's faint violet glow and Kaito's golden flame — shimmered in the dimming light.
Together, they looked like gods standing at the edge of creation.
For all their strength, they didn't see themselves as divine.
They were just two friends — two boys from another world who refused to let go of who they were.
As night approached, stars began to pierce through the twilight.
The wind grew colder, carrying whispers of the forests below.
A faint sound — maybe a distant roar — echoed through the valleys, reminding them that danger still lurked everywhere.
Kaito stood up, stretching his arms lazily.
"Alright. Tomorrow, we pack up and go exploring. I'm done living like a mountain hermit."
Suho smirked.
"Exploring, huh? You mean finding a girlfriend."
"That too!" Kaito said proudly. "But who knows, maybe I'll find a cute elf girl who likes fire magic."
"And burns you alive when you flirt too much," Suho added, deadpan.
Kaito laughed, unbothered.
"Worth it."
Suho shook his head, smiling softly.
"You never change."
"And you still talk too much like an old man," Kaito teased.
Suho sighed, rising to his feet. His long coat swayed in the breeze, the runes along the hem glowing faintly as if breathing.
Kaito's cloak flapped beside him, the ember-like sparks dancing in the wind.
For a brief moment, they looked less like humans and more like legends — two beings born from myth, staring at a world waiting for their next move.
They stood side by side, staring down the mountain path that spiraled into the misty forest below.
The world beyond was unknown — maybe full of danger, maybe full of stories.
But one thing was certain: they wouldn't face it alone.
"Hey, Kaito," Suho said quietly.
"No matter what happens next… let's not change, alright?"
Kaito turned, his yellow eyes shining like molten gold.
"Heh, what kind of idiot do you think I am?
You're my best friend, Suho. Even if this world ends — that won't."
Suho grinned.
"Good. Because I'm not planning to lose you to some elf girl."
"Don't worry," Kaito said, smirking. "I'll make sure she likes you too."
They both burst out laughing again, the kind of laughter that carried through the quiet night and echoed through the world like a promise.
Somewhere far below, deep within the forest, a faint light flickered — like a signal waiting to be found.
But for now, at the top of Mount Eltaris, under a sky full of stars, two best friends laughed like it was the first day of their new world.
"Bestfriend never ends — even after we got summoned to another world."
The night was quiet — almost too quiet.The flickering fire in the cabin crackled softly, its glow painting warm shadows on the wooden walls.Outside, the forest slept under the shimmering gaze of countless stars, a sky so vast it felt like eternity itself was watching.
Inside the cabin, Kaito was already asleep, his breathing steady and calm. His black hair lay scattered over the pillow, and a faint ember-like glow pulsed at his fingertips — a sign of his fire magic still lingering even in rest.
But Suho couldn't sleep.
He lay on his bed, eyes open, staring at the ceiling beams above him.The silence of the room pressed against his chest, heavy with memories.
Slowly, he sat up. His silver-white hair caught the faint light of the dying fire, gleaming like snow under moonlight.He looked toward Kaito for a moment and smiled faintly.
"You sleep so easily, huh… must be nice."
He stood, grabbing his black coat from the chair, and quietly opened the door.
Outside, the air was cool and crisp. The mountain breeze brushed against his face, carrying the scent of pine and mist.The world around him glowed silver under the moonlight — peaceful, still, untouched.
He walked a few steps away from the cabin and stopped near the edge of the cliff.The entire forest stretched before him, glowing faintly beneath the stars.It was beautiful… and yet, something about that beauty felt lonely.
Suho took a deep breath, his crimson eyes reflecting the sky.
"This is… a beautiful night."His voice was barely a whisper, carried away by the wind.
For three years, this mountain had been their world — their home.He remembered the laughter, the battles, the quiet dinners under the stars. Every rock, every tree, every breeze carried a piece of their story.And now… tomorrow, they would leave it behind.
He didn't know why, but a small ache formed in his chest — a feeling he hadn't experienced in a long time.Not sadness, not fear — just… a quiet sense of farewell.
"I guess I'll miss this place," he murmured softly.His red eyes turned toward the cabin where Kaito slept peacefully."We've come a long way, haven't we, Kaito?"
He smiled faintly, his voice trembling just slightly.
"Three years of silence, and we never gave up. You always said we'd find something someday…"He looked back at the stars."Maybe… that day's coming soon."
As he stood there, the night seemed to hold its breath. The forest below was still, and the world around him glowed with starlight.Then, suddenly—
A faint sound.
It was distant, soft, almost uncertain — but unmistakably human.
A scream.
A girl's voice.
Suho froze.
"...What?"
The sound came again — faint, echoing through the forest below.It was followed by a deep, guttural roar — something primal and monstrous.
His heartbeat quickened.But he didn't move. Not yet.
He frowned, rubbing his temple.
"No way. That has to be my imagination."He exhaled slowly, forcing a calm smile."There's no way… a human could be here. Not after three years."
He turned back toward the cabin — but then it came again.This time, louder. Closer.
The sound of trees breaking. A scream of fear.A monster's growl.
His calm expression vanished.
"...That's real."
In an instant, his eyes glowed faintly crimson. A thin aura of violet light shimmered around his body as his senses expanded, scanning the forest below.
There — a faint mana signature.Huge. Wild.And another, smaller — trembling, weak… human-shaped.
"Got you."
He vanished.
The forest floor exploded in a swirl of wind as Suho appeared, his boots crushing the leaves silently.The air here was thick with tension — and blood.
Ahead of him, a massive beast — its body a mix of fur and stone — towered over a small figure.Its jaws dripped with saliva, eyes glowing crimson.The girl had fallen to the ground, one hand clutching her leg, her face pale in fear.
But what caught Suho's attention were her ears — wolf-like, twitching even as she trembled.A beastman.
He muttered quietly.
"A beastman…? Here?"
The creature lunged forward before he could finish the thought.But Suho didn't move.He simply raised his hand.
A faint hum of mana filled the air — and in the next instant, the monster was gone.Cut cleanly in half.
No sound. No struggle. Just silence.
The forest wind blew softly, scattering the creature's ashes into the night.
Suho lowered his hand and turned toward the girl.She was staring at him wide-eyed, her body trembling. Her silver-grey hair fell over her shoulders, her wolf ears flicking in shock.
Her voice came out sharp, defensive.
"W-who are you!?"
Suho blinked, scratching the back of his neck awkwardly.
"Ah… sorry. Didn't mean to scare you. I'm not a bad guy. I just saw you being chased by that thing."
The girl hesitated, her eyes scanning him suspiciously — his long white hair, his calm red eyes, his black coat fluttering in the breeze.He looked… too composed. Too strong.
After a moment, her shoulders relaxed slightly.
"...I see. Then I owe you my life."Her voice softened, embarrassed."Sorry for speaking rudely. I thought you were another monster."
Suho chuckled lightly.
"No problem. You're not the first to call me a monster."
He took a step closer and noticed blood dripping down her leg.The wound was deep — too deep for a normal healing potion to fix.
His expression turned gentle.
"You're hurt."
Before she could respond, he knelt down and placed his hand above her wound.A faint violet light glowed from his palm, wrapping her leg in warmth.The torn flesh began to knit together, the pain vanishing in seconds.
The girl's eyes widened.
"T-that's… advanced magic! Who are you, really?"
Suho smiled softly, shaking his head.
"Just a human who lives on this mountain with his friend. Nothing special."
"Nothing special…?" she muttered, glancing at the ashes of the monster. "You killed a Stonefang Beast in one strike…"
Suho shrugged.
"Guess I got lucky."
The girl frowned slightly, clearly unconvinced, but she sighed.
"Alright, mister lucky. I'm… grateful anyway."
She brushed her hair aside, her wolf ears twitching slightly as she looked up at him.
"My name's Aria Luneveil. I was searching for fruits in the forest before it got dark. I lost my way, and that thing found me before I could find the path back."
Suho nodded, his expression calm.
"I see. That explains it. You shouldn't be out here alone — especially at night. This mountain is crawling with monsters."
Aria looked down, embarrassed.
"I know… I was just hungry. I didn't think I'd go this far from my village."
Suho raised a brow.
"Village? There's a village nearby?"
"Yes. Hidden deep beyond the western ridge," she said softly."My people — the beastmen — live there in secret. We don't usually wander this high up. You must be very far from the human lands."
Suho's heart skipped.So there were others.After all this time — real people. Real life beyond the silence.
He hid his excitement behind a calm smile.
"I see. Then it looks like I'll finally have someone to visit."
Aria tilted her head.
"Visit?"
"Yeah," Suho said. "My friend and I have lived up here for years without meeting a single soul. You're the first person I've met in this world since… well, since we arrived."
Her eyes widened slightly.
"Since you… arrived?"
Suho realized he'd said too much and quickly chuckled.
"Ah, long story. I'll tell you next time."
He stood and offered her his hand.
"You can't walk properly, right? Come on, I'll help you get somewhere safe for tonight."
Aria hesitated, then placed her hand in his. His touch was warm, steady — oddly reassuring.
"...Thank you."
Suho smiled softly, helping her stand.The moonlight wrapped around them like a silver veil, and for the first time in years, Suho didn't feel alone.
As they began walking through the silent forest, Suho glanced at her from the corner of his eye.The faint shimmer of her wolf ears, the glow of her silver hair under the moon — it felt almost unreal.
He whispered under his breath, almost to himself.
"So there really are others in this world…"
Aria looked up.
"Hmm?"
Suho smiled faintly.
"Nothing. Just talking to myself."
When they reached a small clearing, Suho stopped.
"You should rest here. I'll keep watch until morning. It's safer that way."
Aria looked at him, surprised.
"You're… really kind. For a human."
"Don't let that fool you," Suho said with a smirk. "I'm only doing this because my friend would scold me if I let someone die."
Aria giggled softly, her wolf ears twitching in amusement.
"Your friend sounds nice."
Suho's eyes softened.
"Yeah. He's an idiot… but he's the best one I've got."
He looked up at the stars again, his crimson eyes reflecting the sky.For the first time, the night didn't feel empty.
The moon hung high above, watching silently as the boy who once lived alone under the stars met someone who would soon change his fate.A faint wind brushed through the trees, whispering softly between the leaves — as if the world itself had begun to awaken again.
And somewhere back at the cabin, Kaito Sai stirred in his sleep, unaware that Suho's quiet night had just rewritten the course of their destiny.
The faint sound of crickets faded as dawn approached.The world outside the cabin began to glow gently — the kind of soft gold that only came after a night of stars.Inside, everything was calm. The small wooden house was filled with the scent of pine, embers still glowing from last night's fire.
Suho opened the door slowly, careful not to wake Aria, who leaned slightly against his arm.Her silver hair shimmered faintly in the moonlight, her small frame trembling with fatigue.He guided her to the simple bed near the corner of the cabin — the one usually used for spare gear — and smiled faintly.
"You can rest here for tonight. It's warm and safe."
Aria blinked up at him, her wolf ears twitching nervously.Her cheeks were slightly pink.
"A-ah… thank you. I… I've troubled you too much already."
Suho waved a hand dismissively, his tone calm and kind.
"It's fine. You're still a kid. How old are you, anyway?"
Aria hesitated, fidgeting slightly with her fingers.
"Um… twelve."
Suho blinked.
"Twelve? Really?"
She tilted her head, confused.
"Y-yes… is that a problem?"
Suho smiled softly, shaking his head.
"No, no. It's just… I was thinking maybe I finally found myself a little sister."
The words left his mouth before he realized how they might sound.Aria froze.Her eyes widened, her cheeks burning bright red.
"L-little sister!?"
Suho looked at her, puzzled.
"Huh? Yeah. Why?"
Her wolf ears twitched wildly, and she looked down quickly, covering her face.
"N-nothing! Forget it!"
Suho blinked, still confused but too tired to question further. He gave a small sigh and smiled gently.
"Alright then. Get some rest. We'll talk more in the morning."
Aria nodded quickly, still avoiding his gaze.She curled under the blanket, her silver tail wrapping around her legs like a soft pillow.
Suho took one last glance at her, making sure she was comfortable, then walked toward his own bed.The room grew quiet again — peaceful, warm, safe.And soon, both of them drifted into sleep.
The morning sun spilled through the window, lighting up the cabin in gentle gold.Birds chirped in the distance, and a cool breeze swept through the open window.All was peaceful.All was perfect.
Until—
"S-SUHO!!!"
The shout practically shook the entire mountain.
Suho groaned, eyes still half-closed.
"...Kaito, why are you yelling so early…?"
But before he could sit up, he noticed something strange.Something warm…And soft…
He looked down.
And froze.
There, curled up against his chest, was Aria — still fast asleep, her small hands gripping his shirt tightly.Her silver tail rested across his waist, and her wolf ears twitched gently as she breathed.
Suho's entire body went stiff.His crimson eyes widened.
"Wha—What the—"
Before he could even think, Kaito burst through the door, his eyes wide and mouth hanging open.
"SUHO! WHAT THE HELL IS THAT!?"
Suho blinked rapidly, confused and flustered.
"W-what do you mean that—"
"That!!" Kaito pointed dramatically. "That cute wolf-eared girl wrapped around you like a body pillow!"
Suho looked down again.And now, fully awake, he realized exactly how close she was.Their faces were only inches apart. Her soft breathing brushed against his collar.His entire face turned crimson.
"AAAAAAAAHHH!!"He jumped up so fast the blanket flew into the air.
Aria, startled, blinked her sleepy eyes and rubbed them softly.
"Mmm…? Suho? What's wrong?"
Suho stammered, pointing helplessly.
"A-Aria!? Why—how—when did you—?!"
She blinked again, confused, and then slowly remembered.
Her eyes widened. Her face turned as red as a sunset.
"I—Last night… I woke up, and I couldn't sleep… so I—I thought maybe if I just stayed near you—"
Her voice faded into a squeak, her wolf ears drooping in embarrassment.
"I-I'm sorry!!"
Suho covered his face, groaning.
"It's fine, it's fine, just—just don't scare me like that!"
Meanwhile, Kaito stood by the door, arms crossed, trying and failing to hold back his laughter.
"Pfft… hahahahaha!! Oh man, Suho, you've got a girl cuddling you already!? You move fast!"
"Shut up, Kaito!" Suho snapped, his face burning even more.
"No wonder you went out for 'fresh air' last night," Kaito teased, grinning ear to ear. "Didn't expect you to bring home a beastgirl!"
"She's just a kid, idiot!"
"Exactly! A kid who apparently loves you already!"
Suho groaned, running a hand through his hair.
"You're impossible…"
Aria, still red-faced, sat up, looking between the two boys nervously.
"U-um… are you two… always like this?"
Kaito smirked.
"Pretty much every morning."
Suho sighed.
"Don't listen to him. He's insane."
Kaito leaned closer, eyeing Aria curiously.
"So, who exactly is this adorable wolf girl, anyway?"
Suho answered calmly, though still visibly flustered.
"She's a beastman. I found her in the forest last night being chased by a monster. She was injured, so I brought her here to rest."
Kaito blinked, surprised.
"Wait… there are beastmen here? You mean there's an actual village nearby?"
Suho nodded.
"Apparently so. She said she got lost while looking for food."
Kaito let out a low whistle.
"Wow. After three years of nothing but monsters and trees, you finally find an actual person. And she's cute. You lucky bastard."
Suho shot him a glare.
"Don't start."
But before they could argue further, a small sniffle broke the air.Both turned to see Aria, tears welling in her golden eyes.
Suho's expression softened immediately.He knelt down beside her.
"Hey… what's wrong?"
Aria wiped her eyes with her sleeve, voice trembling.
"You said you were… going to send me back to my village…"
Suho blinked.
"Yeah… isn't that what you want? Your parents must be worried."
Aria shook her head, her voice breaking slightly.
"No… I don't want to go back! I want to stay with you!"
Suho froze.Kaito's grin vanished.
"You… what?" Suho asked softly.
Aria's eyes brimmed with tears as she looked up at him.
"When you saved me… it felt warm. Safe.No one has ever protected me like that.I don't want to go back to being alone. I… I want to stay with you, Suho."
The words hit him harder than any monster could.For a moment, he couldn't find his voice.
Kaito whistled quietly, trying to hide his surprise — and a bit of jealousy.
"Man… she really likes you, huh?"
Suho sighed softly, brushing a hand through his hair.He didn't want to break her heart, but he also didn't want her to get hurt.
"Aria," he said gently, "your parents will be worried. You have to go back. But…"He smiled faintly, warmth returning to his voice."You don't have to be sad. Because from now on… you're my little sister."
Aria froze.
"W-what…?"
Suho smiled softly, his crimson eyes warm.
"I told you last night, didn't I? I wanted a little sister. So… from now on, you're part of our weird family."
Aria's face turned crimson again, but this time, her tears stopped.She looked down shyly, her voice barely audible.
"Then… I'll go back. But only if you promise one thing."
Suho tilted his head.
"What thing?"
She clenched her tiny fists, gathering courage. Her wolf ears stood straight up.And then, with a sudden burst of emotion, she shouted:
"You're not allowed to date any other girl!!"
The cabin went silent.
Suho blinked.
"...Huh!?"
Kaito burst out laughing so hard he nearly fell over.
"PFFFT—HAHAHAHA! Oh my god, Suho!! You're already banned from dating! By a twelve-year-old!!"
Suho's face turned bright red.
"W-wait, WHAT!? Why!? I haven't even dated anyone yet!!"
Aria's face was even redder than his, but she didn't back down.
"I-I don't care! If you want to date someone… then date me!"
The words hit him like lightning.
Kaito dropped to the floor, laughing hysterically.
"HAHAHAHA! She confessed!! SHE ACTUALLY CONFESSED!! Oh, Suho, you're doomed!"
Suho just stood there, speechless, face redder than fire.
"W-wait, what do you mean 'date you'—you're twelve!!"
Aria hid her face in her hands, squealing in embarrassment.
"I didn't mean now! I mean—someday! When I'm older!"
Kaito was wheezing now, clutching his stomach.
"Oh, this is gold! Absolute gold!"
Suho threw a pillow at him.
"Shut up, Kaito!!"
But even he couldn't stop the small smile tugging at his lips.Somehow, despite the chaos, it felt warm.Alive.
After three years of silence and emptiness, the sound of laughter filled the cabin again.
Later, as things finally calmed down, Aria sat quietly on the bed, playing with her silver tail, still blushing from earlier.Kaito grinned, leaning against the wall.
"So, big brother Suho, what's the plan now?"
Suho sighed.
"We'll escort Aria back to her village first. After that… maybe explore a bit."
Kaito smirked.
"Sounds good. Just make sure your new little sister doesn't bite you when another girl talks to you."
"I said shut up, Kaito."
Aria giggled softly, her laughter light and innocent.
For the first time in years, the mountain no longer felt lonely.Three souls now shared its silence — a warrior, his brother, and a little beastgirl who had unknowingly opened their hearts again.
