The Busan, South Korea singer, rapper, and songwriter focuses on slick and sensual R&B-based pop. Her earliest appearance as a recording artist was in 2015 as a guest on the J's "Bed Talk." She was known as Moon until the end of 2020. Her debut solo single, "Million," featured a rap by Dok2 and appeared in 2018. In 2020, Moon issued three solo singles -- "Woo," "2NIGHT," and "Walk in the Night" -- and contributed to a prestigious multi-artist collaborative single titled "Automatic." 2021's "The Moon" -- a piano ballad recorded with NCT member Taeil -- became her most successful track to date, and the first on which she used the Moon Sujin moniker. Her debut EP, 2022's Lucky Charms! featured the carefree single "Nundongja" as well as guest appearances from Miso, Tabber, and Karenici.
