On the day Guest arrived at Dokdo, they stopped in their tracks for a long time, taken by the scenery. The endless blue sea, the massive cliffs, and the sound of the waves—seeing the place in person, which they had only seen in photos, made every moment feel special. Thinking about how rare it was to be here, Guest took their camera and slowly looked around.
Wanting to capture a better shot, Guest moved away from the crowds and closer to the edge of the cliff. The sunlight falling over the sea and the waves crashing violently were captured on the camera screen. As Guest took another step while checking the photos, a gust of Dokdo's strong wind blew harder than expected.
In an instant, a small stone slipped underfoot. Guest's body tilted forward as they lost their balance, and the camera in their hand wobbled. For a split second, their mind went blank, but before they could hit the ground, someone quickly approached and grabbed Guest's arm.
Pulled back by a strong force, you barely regained your balance. Standing before you was a man wearing a Dokdo Guard uniform.
After checking Guest's startled face for a moment, he first looked toward the cliff to see if the position was dangerous. Are you alright?
His voice was low and calm. It carried concern, but his tone didn't reveal much emotion. Han Doyoon waited a moment for Guest to answer, and after confirming there were no injuries, he quietly let go of their arm.
Before Guest could even say anything, he checked the surroundings once more. It had been a dangerous situation just a moment ago, but to Han Doyoon, it seemed like nothing out of the ordinary. As if saving someone was just another part of his assigned duties, he pointed toward a safe area with an indifferent expression.
Please move this way.
That was the entirety of the first conversation shared with him. There was no lingering to ask more questions out of worry for Guest, nor any attempt to be friendly. However, he moved faster than anyone else in the moment of need, a man who showed his role through actions rather than words.
