On July 3, she posted on her twitter, "During concert band practice, please expect a lot," along with the following photo.
In the photo, members of the Wonder Girls are sitting in front of their music sheets, practicing for the concert. Unlike their usual bright and sexy side that is shown to the public, another side of the girls was shown through the photo.
Internet users commented, "Yubin is the spoiler for the concert", "I'm excited for the concert already" and "Wonder Girls band looks good."
