We always read fanfic that Taeyeon so dominate, not shy, who likes to protect people, who are ignorant or sometimes you make Taeyeon male or if , you make her inter right? If Tiffany anyway, you make it shy, feared, always Taeyeon to protect her or otherwise.

Try to change them. You imagine Taeyeon's behavior as Tiffany and Tiffany's behavior change as Taeyeon's behavior.

This is my idea, if you agree, comment. if you don't like my idea, you can go !! Bye##
