Shanghai Romance is a 2011 song by Orange Caramel, the South Korean girl group known for bright, concept-driven pop and playful visuals. The track draws on a retro 1930s Shanghai theme, matching its music video's vintage costumes and theatrical staging. Shared through K-pop fan channels such as 1theK, it became a favourite among fans of second-generation K-pop, and short clips have continued to circulate in fan edits, dance covers and nostalgic compilations because the melody is instantly recognisable and easy to drop into a short video.
