K-pop is bigger than ever — but so far, mainstream media attention in the U.S. has been focused on boy bands like NCT 127, Monsta X, and especially Time magazine cover-story sensations BTS.

But now, with the full-scale Stateside launch of her solo career, she’s leading the U.S. invasion of female K-pop stars.
