A medium shot from a side angle captures a beautiful young woman sitting alone in a luxurious Gangnam cafe during a rainy day. She has long, straight black hair and a sorrowful expression, gazing deeply down at her espresso cup with a single tear silently rolling down her cheek. She is dressed in high-end designer clothing made of rich, textured fabrics. Her slender, delicate fingers are gently gripping the handle of the small white porcelain espresso cup. The background shows the blurred interior of a sophisticated cafe with large glass windows streaked with raindrops, revealing the muted grey cityscape of Gangnam outside. The atmosphere is melancholic and quiet, lit by soft, diffused indoor lighting that contrasts with the cool, blue tones of the rainy exterior, creating a mood of lonely elegance and deep sadness.
