Thus, Park Ji Eun will complete her activities as a member of PURPLE K!SS as of today (November 18), and PURPLE K!SS will resume promotions as 6-members.

We apologize for concerning fans, and also wish for Park Ji Eun's speedy recovery, as well as the best in her future plans. We ask that fans continue to support Park Ji Eun in her decision, and also continue to support the 6 members of PURPLE K!SS as they resume activities.
