Girls' Generation's member Sooyoung revealed her thankful heart to her fans before their comeback.

Girls' Generation released the teaser video of their 4th mini album's title song "Mr. Mr." yesterday, officially announcing their comeback. As it has been a whole year since their last album, many members seemed excited.

Sooyoung said, "Our comeback was finally announced. I think the empty one year was able to be filled because the members communicated through SNS. As you've waited a long time for our comeback, we wanted to make our song and performances that much more perfect so we took our time perfecting it."

She said, "Our Sowon (Girls' Generation's fan club) only deserves the best. You have the right and you can ask for more."

Girls' Generation will be releasing their title song "Mr. Mr" on February 19 and the rest of their album on February 24.
