Former Nine Muses member and super model, Rana revealed her reason for leaving the group was in the December 15 broadcast of "Challenge 1000 Songs."
In the said episode, host Lee Hwi Jae introduced RaNa as somebody who "really can't sing," and because of that the environment had been a little bit lighter.
At that time, Rana was partnered to Lim Ji Yeon, who is 1984's Miss Korea. Lim Ji Yeon then said, "I asked her earlier why she quit being a singer, and said, 'You'll see later. I can't sing.'" Rana who was embarrassed, had hit her senior lightly on her shoulder.
Host Jang Yoon Jung then jumped in, saying, "I saw it too. She really can't sing."
Rana had debuted in 2008 by receiving the first place at a supermodel pageant. Rana then was among Nine Muses since they debuted in 2010. However, after a short time she left the 9-member group Nine Muses together with Bini in 2011.
