KBS 2TV's 'Hello' invited Junghwa and Hani of trendy girl group EXID onto the show on January 12 where the girls talked about how things have changed since they hit success with "Up & Down."

Shin Dong Yup said, "The song 'Up & Down' came out in August last year, but as your diligent performance was taped and the video became a really hot topic, you guys managed to rise to first place from outside the top 100 on music charts."

Jung Chan Woo asked, "Now that you guys rose to the top, did anything change?" Junghwa made everybody laugh with an interesting response: "The atmosphere at the company got a lot better.  The older employees at the agency send us texts while they are in meetings as late as 3 in the morning."

She further revealed how happy the mood was at the agency by saying, "They happily contact us with [texts like], 'It's 3 AM right now, but we are still in a meeting,'" showing how much the employees were enjoying the work now.  

Jung Chan Woo said, "Before this, was the atmosphere in the company a mess?" making everybody laugh.
