Билборд ко Дню Рождения Айдола в Метро

Realistic wide-angle documentary photograph inside a clean Korean subway station corridor with tiled walls, ceiling panels, a polished gray floor, and platform signage in the background. On the left foreground, a young woman with long dark hair wearing an [oversized blue denim jacket, white graphic T-shirt, and black mini skirt] stands smiling with her face anonymized by a soft rectangular blur, posing with both hands pointing enthusiastically toward a giant illuminated wall billboard. The billboard fills the right two-thirds of the frame in a black border, displaying a celebratory K-pop fan birthday advertisement featuring a matching portrait of the young woman with a soft blur over her face. The billboard features a [pastel pink and turquoise blue] gradient background with bokeh, sparkles, floating petals, small wing and heart accents, and a small crown above a ribbon banner. Korean typography on the billboard includes ribbon text reading "[여신 탄신일]", large central name "[윤슬]", congratulatory subheadings below, the date "[1996.02.15]", and tiny bottom English text reading "YOONSEUL DAY • ALWAYS BE WITH YOU • FROM YOUR STARLIGHT". Natural subway fluorescent lighting, glossy floor reflections, slight wide-angle lens distortion, crisp billboard graphic design, and an empty corridor.
