ever wondered about the story behind SNSD's Mistake? We all know that Yuri wrote the lyrics but the story behind it, we all don't know.   This is pure fanfiction :) Hehehe ... I know I'm still working on my 2nd fic but this really got in my mind and I wanted to write it down.   *NOTE: the pictures I used are NOT MINE ... I got them from the internet .. credits to the owners :) but I edited the poster .. weeeeee :)
