Though Haseul wants to continue greeting her fans as promised at their fan meeting last month, it has been decided that for the sake of her focusing on her mental health that she will take a temporary hiatus from promotions and other scheduled activities.
Haseul will be spending time with her family and her group members and focus her strength on recovering. Until such time, she will not be promoting the new album #.
We sincerely apologize to all of the fans who love LOONA for the sudden news. The remaining 11 members of LOONA will continue promotions as scheduled.
We will release a statement when we have an update from Haseul's doctor on her condition.
We ask for the fans' understading and to keep Haseul in their thoughts.
