'Expected' because of their own clueless assumptions. Please take their comments for what they are bitter hate comments. I hope everyone is aware that this post has been flooded with some pretty infamous Jessicastans who are extremely anti SNSD (like hyogurt here being a long time Taeyeon/Tiffany/Sunny anti) and love spreading shitty rumors about them.

Tiffany herself already confirmed that the plan was always for Taeyeon and Tiffany to debut as a duo after LSM saw their Lady Marmalade performance, Seohyun only got added way later and by then Seohyun was the only one not busy with anything.
