The October 3 episode of KBS 2TV's 'Yoo Hee Yeol's Sketchbook' featured the lovely ladies of TaeTiSeo!  

Early in the interview, Taeyeon said, "I find growth to be unusual.  From the viewers' perspective, they look at the image."  Seohyun added, "When we debuted, there were a lot of boy groups.  Now, there are a lot of girl groups, so I'm happy."

The girls revealed that they had a big hand in their album, 'Holler,' showing their growth as artists.  The visual directing and stage styling for album 'Holler' was done by Tiffany while the song selections were done by Taeyeon.  Seohyun revealed that she personally wrote the lyrics for "Only U," and was taken aback when Yoo Hee Yeol read out her lyrics about the longing for one man and asked what in the world had happened.

Yoo Hee Yeol then made Tiffany flustered when he said that if Seohyun had any questions about dating for lyrics, she could ask Tiffany, who is known to be dating 2PM's Nichkhun.

The girls were also asked if they wanted to work with any agency or composer outside of SM to which Tiffany chose YG's Teddy, Taeyeon chose Mystic89's Yoon Jong Shin, and Seohyun chose JYP's J.Y. Park.  As soon as Seohyun mentioned JYP, the whole room started laughing and Tiffany cutely could not stop laughing.

The girls also performed "Holler," "Only U," and "Cater 2 U," so check out those stages and their interview below.
