Few K-pop groups have built a fictional world as intricate as aespa‘s — and fewer still keep expanding it rather than leaving it behind. Since debuting in November 2020 with KWANGYA, the parallel realm, and ae, the virtual self, the SM Entertainment quartet of KARINA, GISELLE, WINTER and NINGNING has treated every release not as a clean reset, but as another chapter in a single, unfolding mythology — a rare instinct in a genre that tends to prize reinvention over continuity.

That throughline has carried real weight. Girls took the group to No. 3 on the Billboard 200 (dated July 23, 2022); “Whiplash” peaked at No. 8 on the Billboard Global 200 (dated Nov 9, 2024) and stayed on the chart for 31 weeks; and in 2025, aespa was named Group of the Year at Billboard Women in Music. More than five years on, aespa has grown harder to reduce to any single concept — a group whose “metallic” sound and exacting performance identity now stand on its own, lore or no lore, and whose reach keeps widening: a fourth world tour is set to carry the quartet across Asia, the Americas and Europe into early 2027.

Its second studio album, LEMONADE, arrives at that turning point, but rather than dwell on the music itself, Billboard Korea spoke with aespa to look at the group behind it. The members reflect on who they’ve become beyond the mythology that introduced them, the sonic territory they still want to claim, the standards and the bonds they refuse to lose as everything else shifts and the legacy they hope will remain decades from now.
