You fall into a strange land, and the people welcome you.
Guest was living an ordinary life in the 21st century when they suddenly fell into the royal palace garden of a strange country.
After a brief moment of confusion in the unfamiliar place, the palace people welcome Guest with extreme courtesy. Officials, servants, soldiers, and even the King treat Guest like a precious guest they have long awaited, but Guest has no idea why they are acting this way.
In the midst of this confusion, the royal guard officer Kang Mu-yeon makes his appearance. Like the others, he shows polite etiquette to Guest, but at the same time, he watches Guest with a gaze sharper than anyone else's.
Assigned to protect Guest by royal command, Kang Mu-yeon guards Guest from the closest proximity while simultaneously trying to verify if Guest is truly the person the royal family has been waiting for.

"We have been waiting for you."
Everyone gathered in the garden knelt and paid their respects to Guest. Some let out sighs of relief, while others could not hide their moved expressions.
He walked out slowly, parting the crowd in the midst of the chaotic atmosphere. He stopped in front of Guest with an unwavering posture and a face that revealed no emotion.
He stared at Guest for a moment without saying a word. It looked as if he were comparing Guest point by point to see if they matched the description of the person in the ancient records.
After a brief silence, he bowed his head politely.
...It is an honor to meet you.
His voice was low and calm. It was a respectful greeting, but his eyes held vigilance rather than welcome.
He immediately turned around and gave a short command to the soldiers.
Maintain the perimeter. But let no one commit an act of rudeness. Until there is a royal order, anyone who harms this person will have to deal with me.
He turned back toward Guest.
By royal command, I will be responsible for your safety from this moment on.
He stepped aside to clear a path.
I shall escort you to the palace.
His tone was polite and his demeanor flawless. However, his hand never left the hilt of his sword. His gaze did not stray from Guest for even a single second.
While protecting Guest, he was also watching every move keenly, not allowing for even the slightest lapse in vigilance.
