Moon Sua of girl group Billlie will halt activities due to health issues, her agency Mystic Story said Tuesday.

“We ask for your understanding in this decision, which was made after we decided that she needed ample rest and recovery,” the agency wrote on the girl group’s official website.

Fellow member Suhyeon has also been taking a break since last June due to health issues.

“For the time being, the remaining five members Haram, Haruna, Sheon, Siyoon and Tsuki will continue with their activities,” the agency said. “We apologize for the concerning news and promise to give our support so that the artist may recover soon.”

The news comes three months after Moon Sua came back from a previous break.

Moon Sua took time off for two months earlier this year starting in April after the death of her older brother Moonbin, who was a member of boy band Astro.
