Became The Leader of a Girl Group Destined To Fail

10 years since debut, won the grand prize for 3 years in a row.
Baek Nokha, a female solo idol, has perfect visuals, skills, and personality.
If it’s fandom, then she has a fandom. If it’s popularity, then she has popularity.

“…What’s up with these unmanaged vocal cords?”
Back to 10 years ago!
It’s not her own body, but someone else’s!
[Congratulations! You have became ‘Yoon Cheong’]
[From now on, you must save the destined to fail girl group, ‘Steel Blue’!]
