Is their proof or documentation of this? I never knew about this, and if she was supposed to be in TTS, who was the member that wasn't gonna be in it? I'm assuming Taeyeon would've gotten a spot no matter what, so was it Tiffany or Seohyun who wasn't supposed to be in it?
The original group was taeny +Jessica. It was called TTJ. A writing group that was working for sm posted on their website that they were writing an album for sm new subunit ty, tif, and jessica.. sm said in a statement that the members aren't a done deal (which I don't get why!!) and look forward for more snsd subunits. That ish never happened. I was so waiting for the new subunit after tts debuted. There are ss of the company post, sm statement, and translated comments talking about the statement etc but it's hard to find.
