Girl's Day member Hyeri showed a cute selfie.

On July 10, Hyeri tweeted, "Guess where I am?" with a picture.

In the picture, Hyeri was next to shelves full of files and posing for the camera looking down at her face. Her small slim face and white skin stood out.

In response, people said, "Are you at school? School?" "There are a lot of files.. so your entertainment company?" "Your face is so small."

Girl's Day is having their first concert 'Summer Party' on July 13.
