Illuminated by the night sky on March 21, 2024, a symbolic fence stands in the heart of Seoul - the exemplified embodiment of the city's unity. Marked by a sign, the fence paves a path, leading natives and travelers alike through the urban metropolis, past towering fir trees to the distant glow of the streets. This humble urban symbol not only serves as a triumph of transportation, subtly interacting with the trio of cars and the lively twelve, but also mirrors a reminiscent landmark of courage and change—the Berlin Wall Memorial.
