Former AOA member ChoA (Park ChoA) raised concerns about the prevalent use of medication within the singing community. ChoA discussed this pressing issue at the production presentation of the new entertainment show 'Playing Unnies,' which took place on the morning of the 28th at Cinecube in Seoul, hosted by E-Channel and Channel S.

She candidly shared, "Many active friends in K-pop resort to medication to cope. I found myself pondering my own survival in the industry until I encountered these 'unnies' (older female friends)."

She added, "These 'unnies' continue to inspire as living testimonies. I aspire to support my friends in the same way and stand as a testament myself. It's common to see peers grappling with mental health issues, and my wish for them is to not feel overwhelmed, but to pursue their careers with sound mental health and joy."

The first episode of 'Playing Unnies' featured Chae Ri Na, Lee Ji Hye, Ivy, and Narsha, marking the show's debut on that day.
