A unique aspect of Korean girl entertainment is transmedia storytelling. It is now common for K-pop agencies to launch companion webtoons (digital comics) or web dramas that feature virtual avatars of real idols. For example, the girl group aespa exists in a "SMCU" (SM Culture Universe) where their virtual counterparts fight digital villains. This blurs the line between music video and narrative series, drawing in fans of anime and graphic novels who might not initially follow K-Pop.
