hmm, in that video I'm seeing beta Ji-lead (TiSe). Her face is totaly neutralized in the video, no Fi-signals and her smiles say polar Fe - in videos and photos. She has got that prominent cheekbones that can be confused with usage of the elevator/depressor anguli muscle. I don't interpret those expressions in the photos as showing Fi-tension. the second smile (2nd photo) seems quite Fe - even if a bit tricky, because of her cheekbones). Overall, what I am seeing is Ti/Fe usage, but, well, I can be wrong... she's not the most obvious to type.
