§

Three years.

That’s how much ti has passed since I fell into this unfamiliar world.

Every day, I deeply felt the truth behind the words of the brilliant human mind, Professor Einstein: ti is relative. As he said, these three years felt longer than the entirety of my life before.

At first, it was good. I was just a clueless high school student, dreaming and filled with hope, imagining myself as the protagonist of so otherworld fantasy like in the stories I had once read.

That dream shattered in just one week.

It was like a bubble popping.

In a world where I couldn’t understand the language, where I had no protector—thinking I could sohow be special was the mont my fate was sealed.

I fell into slavery.

Still, perhaps luck wasn’t completely absent. The cruel reality that pushed to rock bottom ironically opened a door for survival. It only took one week in this world before I beca a slave, but among the slaves, I was a rather valuable one.

No matter how different this world was, mathematical proof remained a universal truth that transcended dinsions. In this primitive world, my knowledge—just basic middle school math—was more than useful.

The one who bought was the head of a rchant guild, and I beca a calculation slave for over two years. After that, I bought myself back.

I beca a freed slave.

I thought, for the first ti since coming to this world, that maybe I had been lucky, thanks to having such a fair master.

But that was just the starting line.

Status. Appearance. Money. Power... I had none of these. I was still at the very bottom of society. Had I stayed in the guild, things might have been different, but after shedding my slave status and stepping out into the world, my path beca even harsher.

My appearance and skin color marked as a foreigner to them. Even as a freed slave, the stigma of being a forr slave clung to .

I tried to learn magic as my last hope, but it was pointless.

So said I had no talent.

Others said I was too old to even start learning.

Three years may be a small fraction of my life—just a little over ten percent—but those last three years have been the most intense, changing more than any other ti.

And I realized.

There was nowhere lower for my life to sink.

"I have no other choice..."

If I wanted to change this miserable existence, I had to do anything.

No, I had to be willing to do anything.

It took a long ti to reach that determination.

With trembling eyes, I looked at the drawing on the ground.

A circular boundary with geotric patterns and symbols drawn inside it.

A demon’s summoning circle.

Even those who have hit rock bottom fear making a contract with a demon.

But that was the path I chose.

"I summon you."

I began, dropping a blood drop from my already injured fingertip.

Though I had no magic power to speak of, the power in my voice connected with the summoning circle, producing a screech like nails on a chalkboard.

The circle I had drawn would summon a random demon.

It’s a common, easily obtainable summoning circle.

If I was lucky, I’d summon a powerful and kind demon.

If unlucky, I’d get a weak or violent demon.

Or maybe the circle would fail to protect , and the demon would devour on the spot.

'Well, if that happens, I guess that’ll be the end for .'

There’s no further to fall. No more hope to cling to.

This is my last chance. The dead-end of my life.

Either I break through, or I stop right here.

Squinting into the light pouring out of the summoning circle, I chanted the final incantation.

And then imdiately after—

I felt a cold sweat trickling down my spine.

'Wait, did I... did I use Korean instead of the language of this world?'

“I need to cancel this...!”

The light of the summoning circle dimd.

In the fading glow, the figure appeared.

Radiating an aura of mystery.

Through the gap where the light was vanishing, I saw the demon’s face.

It was beautiful.

Far more beautiful than the voice I’d imagined—and that voice had already been captivating enough.

Radiant golden hair shimred with a brilliance that no amount of lted gold could replicate, and features more flawless than any master sculptor could craft. It was so perfect I couldn’t even begin to describe it.

Without realizing it, my mouth hung open, and I stared, entranced by that face.

The demon’s eyelids slowly lifted.

As if being guided by so unseen force, my gaze t the demon’s, and...

I froze.

Contrasting starkly with the warm golden hair, her eyes were a chilling shade of blue.

They were so cold that just looking at them made keenly aware of my own insignificance. Her eyes held a gaze devoid of any warmth, like lifeless minerals.

The daze that had been clouding my mind was washed away, like soone dousing in ice water.

Right. Before was a demon.

A being beyond human comprehension.

Just as humans might casually crush an ant, this demon could erase a human on a whim.

She smiled.

Her lips curved into a delicate, graceful arc, more alluring than anything I’d ever seen.

With a smile on her blood-red lips, the demon spoke in a voice as cold and beautiful as snow.

"Let ask you."

Her tone was flat, devoid of any emotion.

Her voice reaffird that this was, indeed, a demon—a being unlike humans.

“Are you my summoner?”

The smile and voice were just as mask-like as before.

And those inorganic eyes didn’t seem to see as another living being.

But that didn’t matter.

I hadn’t summoned a demon to make a friend.

I responded politely to the demon’s question.

"Yes. I summoned you."

"Very well. But next ti, be more careful."

Indeed, it seed like sothing had gone wrong.

“I knew it... the incantation in this world’s language...”

"Such an outdated offering..."

There was a pause.

“Offering?”

“…?”

Was the issue not my use of Korean but the offering?

Why?

The goat’s head I placed on the makeshift altar was supposed to be one of the demons’ favorite offerings.

"I paid a high price for it..."

“This world, you say?”

I felt a strong sense that our conversation was diverging.

And she seed to feel the sa.

"Wait... is this not Earth?"

For the first ti, an emotion flickered across the demon’s transcendently beautiful, serene face.

It was the look of soone realizing that sothing had gone terribly wrong.

§

Her surprise was brief.

Before long, the demon regained her composure, and we were able to have a serious conversation.

Perhaps it was my social skills, honed through years of survival, that helped pretend not to notice her earlier slip.

Either way, I laid out my story, and the demon patiently listened to my long tale.

Then, with her final confirmation, I was left stunned.

"You were summoned from Earth?"

It was an unbelievable story.

But considering it was a demon, perhaps such a thing was possible.

After all, I had already experienced being transported to another world, so I couldn't completely deny the idea.

And demons, as beings far beyond humans, clearly had powers that transcended human understanding. Just looking at her otherworldly beauty made that fact evident.

She even implied that returning to Earth wasn’t entirely impossible.

To beings like her, even the worlds we don't yet perceive might just be distant places to reach.

I trembled at the thought of the demon’s boundless power.

Hope flickered before .

But just as my heart clung to the idea of returning to Earth, the demon crushed that hope with a single word.

"It's impossible."

“Why…?"

"Because you're not ready yet."

What did she an?

I was prepared to give everything.

Even if it ant mortgaging my soul and handing it over to the demon after death, I would seriously consider it—and, in the end, I’d probably agree.

When a summoner calls upon a demon's power, they must pay in three main ways:

Devotion sent to the demon.

Offerings prepared to summon the demon.

Price paid for borrowing the demon's power.

I was ready to accept all of these: the devotion, the offering, and the price.

But the demon shook her head.

“The power of a demon is far too vast for an ordinary human to contain. You need to grow, beco stronger. Expand your capacity, raise your status. That’s why you ca here, isn’t it?”

As she said that, her once lifeless, jewel-like eyes flashed with sothing alive for the first ti.

It was a gaze that erased any doubts I had about whether or not she was truly a demon.

She extended her hand.

She offered a lifeline.

"You don't need to be discouraged. I'll give you the strength you need to keep moving forward."

As if srized, I took her hand.

"...A contract."

At my words, the demon smiled.

Then, she slowly raised her hand, a bead of red blood forming at her fingertip.

"He who hears my na shall beco my contractor."

With her voice, the droplet of blood fell from her fingertip.

It landed on the summoning circle I had drawn.

Her blood mixed with my own, which I had already spilled on the circle.

"My na is Seir, the one who grants wishes of courtesy."

The demon accepted my desire, took my offering, and asked for no price in return.

§

It felt like a dream.

A ti as fleeting and surreal as a midsumr night’s dream.

Is this what people an when they say they’ve been enchanted by a demon?

‘She said she’d be watching.’

If I wanted to summon her again, all I needed to do was rember her true na.

As I sat alone in the now-empty room where Seir had disappeared, I repeated her words over and over in my mind.

Then suddenly, I realized that I was no longer the sa.

'This... this is magic.'

A strange sensation, impossible to describe, ca from my back.

It was the contract mark—a symbol of my bond with the demon. Through it, I could feel Seir’s magic coursing through .

I sharpened my focus, carefully and calmly trying to control the flow of magic.

Like thick, viscous tar, the black magic responded to my will, bubbling up inside .

There it was.

The magic I had longed for.

For now, it wasn’t much.

The magic trickling through the contract mark was just a small cupful compared to the vast ocean of power on the other side—the limitless magic of Seir.

When Seir ntioned "capacity," she must have been referring to the ability to draw up that entire ocean at once.

But that’s still a long way off.

Still...

"Finally."

I had reached the starting line.

I had grabbed hold of a lifeline while standing on the edge of a cliff.

What I had to do now was learn how to handle this power and increase my capacity.

And I knew the way.

Just as Seir had ntioned, I had co here to seek that answer.

The source of mystery.

Wealth, fa, the unknown—the answers to everything.

In the Abyss.

I stood at the starting line. I had the power to run. I could see the goal.

Now, it was ti to start running.
