Captured at 03:17 am on March 20, 2024, as part of my Korean adventure, this photograph presents the solitary 'bicycle' street sign, illuminated in stark contrast against the seductive backdrop of the urban night sky. The interplay between the artificial lighting and the darkened surroundings highlights both the symbolism of the bicycle sign and the often overlooked beauty of city streets at nighttime, while subtly emphasizing the dynamic coexistence of microcosms within our vast metropolises.
