f(x)'s Luna talked about her popularity.

On the January 30 airing of MBC's 'Radio Star,' Luna revealed she's envious of the great attention the other f(x) members receive from the public. She said, "I wish I can become an issue, even if it's receiving criticism. I comment on my own articles. There are not many comments at all..."

MC Kim Gu Ra mentioned former member Sulli and said, "Sulli receives a lot of the spotlight so how about asking her for advice?" 

Luna reacted startled and said, "She has left the group, so I have examined the other members."

She explained, "I examined Krystal's social media. Krystal gets 400,000 'likes' per post but I get 10,000. I wondered why it's like that and realized people want to see her social media. She has pretty clothes, but I'm kind of a mix of everything. There's makeup, fashion, and dance. It's too much. I need to take some out."
