Her agency, Mystic Story, officially announced on September 12th through their fan cafe, “Billie member Moon Soo-ah will temporarily suspend her activities due to health reasons.”

The agency explained that they believe she needs sufficient rest and stability, hence the decision to temporarily halt her activities, and they kindly asked for understanding from fans.

This announcement comes after fellow Billie member Suhyun also had to suspend her activities due to health issues back in June. As a result, Billie will continue their activities for the time being with the remaining members: Haram, Haruna, Sean, Siyoon, and Tsuki, making it a 5-member group.
