tvN's experimental new reality program 'Mom Is An Idol' has introduced another component of the K-Pop star reboot challenge through its latest teaser. 

In the program's second teaser starring former After School member Kahi, the singer and dancer opened up about the feeling of putting herself on the sidelines in order to raise her children. Now, presented with another opportunity to return to the stage, Kahi revealed her intentions to give this new program her all. 

However, when Kahi stood in front of a panel of pre-selected, currently promoting K-Pop idol group members and sang for her first vocal level test, the judging results shocked her. Seeing the results, Kahi commented, "I had a total mental breakdown. I had no idea I would get such a score. Did I sing that badly?"

Meanwhile, tvN's 'Mom Is An Idol' stars top former K-Pop idols who have now given up their positions on stage in order to play their roles as full-time moms and wives. Stars including former Wonder Girls member Sunye, former Jewelry member Park Jung Ah, former After School member Kahi, and more are expected to take on the challenge of returning to the stage. The program premieres on December 10 at 8:40 PM KST.
