Moon Sua from the group Billlie has temporarily halted her activities due to health issues.

On September 12, Moon Sua's agency, Mystic Story, announced her temporary hiatus due to health concerns.

The agency stated, "Moon Sua has decided to take a break from her activities for health reasons. We've determined that she needs ample rest and stability for the time being," and asked for understanding from fans.

Furthermore, they added, "Starting from today, Billlie's official schedules will proceed with the five members: Haram, Haruna, Seon, Siyoon, and Tsuki. We will notify fans about the potential return date for Moon Sua when it becomes clear."

Moon Sua first gained attention when she participated in Mnet's 'Unpretty Rapstar 2' on September 11, 2015. She transferred to Mystic Story in 2019 and debuted as a member of the girl group Billlie on November 11, 2021. She is also the younger sister of the late Astro member, Moonbin.
