The director's cut of 'THE TaeTiSeo' that aired on October 21 had a lot of goodies for fans that did not air previously on the show.  In one portion, Taeyeon talked about being alone.

She said, "I don't like being alone.  I also want to play or something like that.  However, I want to be alone," revealing that she even liked to go to the beach alone when she was stressed to relieve her feelings.

When the production crew asked why she went to the beach alone, Taeyeon replied, "To tell the truth, I feel suffocated wherever I go, so I do want to go out, but there are so many people when I do, so... Sometimes, I become stressed, so..."

She also talked about her relationship with Tiffany, bringing up her first impression.  The two were known to be very close friends for ten years.  She said, "When I first saw Tiffany, I thought she was older than I was.  Even Tiffany's hair was very bright and I did not feel like she was my peer."

Tiffany said, "My style is the same then and now," explaining how she had been obsessed with movie 'Mean Girls' at the time and liked the Hollywood style.  She continued, "I met Taeyeon for the first time at home as roommates.  At the time, Taeyeon lived at the dorms only on the weekend because of school."

Taeyeon said, "Tiffany is like a vitamin to me because she always gives me bright energy."
