Hello. This is CTD E&M.
Loossemble member Hyeju has cold symptoms, so she will wear a mask when proceeding with the Loossemble 2nd Mini Album [One of a Kind] Fansign (Soundwave) scheduled for today (21st).
Hyeju visited the hospital this morning, and because it is a disease that is feared to be contagious, she will proceed with the schedule, wearing a mask to prevent contagion.
We ask fans for your understanding, and we will do our best for the artist's health and recovery.
Thank you.
