Former SM artist Stephanie talked about the agency's hit girl group Girls' Generation on the October 25 airing of 'Video Star.'  

She chose Hyoyeon as the best dancer out of Girls' Generation, as Stephanie used to be their dance trainer, saying, "Hyoyeon is such a talented dancer.  That's why even during performances, I always trusted her and left her in charge.  I had respect.  There was another friend who was a practice bug (meaning practiced really hard)," and revealed there was yet another member who was so bad at dancing that Stephanie had been concerned.  She asked the other panelists to guess who this member was.

Park Na Rae threw out Taeyeon and Yuri's names, but Stephanie revealed it was Seohyun.  Stephanie said, "At first, she was so timid and quiet to the point I wondered if I should put her in or not, but she worked amazingly hard and followed everybody else." Everybody said, "As expected of Seohyun," in acknowledgment.
