A new episode of On Style's 'THE TaeTiSeo' aired on September 2, again showing the cute and quirky natures of TaeTiSeo members, Taeyeon, Tiffany, and Seohyun, who discussed the surprises that happened throughout their career.

The image of a 12-year-old Seohyun was revealed on the show, and Tiffany said, "When I first saw Seohyun, she was so cute," whereas Taeyeon remarked, "To tell the truth, when I first saw Seohyun, I had no idea we would be in the same group. �People were with people their own age. �I didn't know I would be in the same group as Seohyun."

Seohyun said, "I never imagined I would be in the same team as the unnies. �I had my own peers, too. �I trained with three people my age; I think it's interesting."

Taeyeon said, "It's also interesting that Girls' Generation put out a sub-unit," while Seohyun added, "We are Girls' Generation, but I think that a musical color unique to only TaeTiSeo is forming."

In addition, the girls went shopping again this episode, showing their personality when looking to purchase items. �Seohyun saw a jumper with fur and said, "That looks really warm!" �She told the production team, "I'm the type that really nitpicks about practicality. �I also look a great deal at the prices."

Taeyeon said, "Seohyun likes really soft things. �She likes the casual look more than wearing tight clothes. �A feminine casual look."
