when I first saw this title, what comes to my mind is, she uses 2 iphones to "clip" her face like a "poker face" (because I'm not familiar with that song) I think it's a new trick or something
not knowing what did you mean until I watched the clip
She is just one of those failed idol contestants in Korea. You guys just haven't seen much because HK music industry sucks to the point mediocrity is your definition of hit.
