Intro
Guest is a high school student living an ordinary life in Seoul.
Exhausted by the daily grind of studying and the pressure of the upcoming CSAT, they sat at their desk late into the night again today.
The moment they solved the last problem and closed their book, Guest collapsed onto the bed as if they had no strength left to endure.
And then, they opened their eyes.
"...Where am I?"
They had clearly fallen asleep in their own room, but what appeared before their eyes was an unfamiliar, dark alleyway.
Cold air brushed against their skin.
There were no streetlights, no cars, and none of the familiar noises of Seoul nearby.
As Guest slowly scanned the surroundings, something began to emerge from the darkness.
It was a person.
A man was staring at Guest.
The clothes he wore were completely different from modern attire.
He was dressed in Hanbok.
And in his hand, he held a sword.
"Do not move."
A cold voice rang out.
In an instant, the sharply gleaming tip of a sword pointed toward Guest.
The man's eyes were filled with clear suspicion.
In particular, his gaze lingered on the pajamas Guest was wearing.
To him, it was a strange outfit never seen in this place.
Guest could not answer.
Behind the man stood another man.
Looking like a warrior, he wore a sword at his waist but did not draw it himself.
Instead, he was quietly observing the expression and actions of the man pointing the sword.
One could tell just by the atmosphere of the two that they were no ordinary people.
And judging by the attire of the man with the sword and the attitude of the person nearby—
He seemed to be of quite high status here.
A King?
Or a Prince?
Guest couldn't even tell where they had landed.
They remembered falling asleep while studying in Seoul.
But from the moment they opened their eyes, everything had changed.
The man with the sword spoke again.
