Chuu is a South Korean singer who first became known as a member of the girl group LOONA, introduced in 2017 during the group's pre-debut rollout and associated with the bright single "Heart Attack." After parting ways with LOONA's original agency, she signed with the label ATRP and made her solo debut on October 18, 2023 with the EP "Howl." The five-track release moved away from her earlier cheerful image toward a more emotionally direct sound, and it performed strongly on worldwide iTunes album charts on release. Outside of music, Chuu became widely recognized through variety and television appearances, which broadened her public profile in Korea beyond her core fanbase. "Howl" topped iTunes album charts in numerous countries on its release, a strong commercial showing for a soloist's first record, and its title track presented a more vulnerable, emotionally honest side of the artist. As a fourth-generation artist relaunching independently, she represents the wave of former LOONA members who continued their careers separately, building solo identities distinct from the large-ensemble concept that defined their original group.
