Girls-Generation's subunit TaeTiSeo made an appearance on 'Yoo Hee Yeol's Sketchbook'.

On the episode that aired on June 1st, the girls explained how their subgroup was established, and the stories behind their debut.

Member Taeyeon revealed that her father was once a vocalist for a neighborhood band, proving she inherited some of his talent.

Member Tiffany shared that while living in America, Tiffany's brother had encouraged her to audition at an event and she had tried out. Though she wasn't selected, Tiffany did receive a number of business cards from different agencies. Tiffany who was just beginning to learn about K-Pop at the time was a fan of BoA, and decided to join SM Entertainment after learning that BoA was an artist under SM. Three weeks later, Tiffany who was living overseas packed her bags and left for Korea.

Seohyun admitted her dream was to become a pianist. She briefly sang a song that she auditioned with 10 years ago. The maknae then revealed that her dream was to become a singer-songwriter, and Yoo Hee Yeol displayed his affection for her, telling her she could call him whenever she experienced writer's block.

Each of the members covered a song as well with Tiffany covering Adele's "Rolling in the Deep", Seohyun covering Pixie Lott's "Jack", and Taeyeon covering Rihanna's "Take a Bow".
