G-Friend's Yuju talked about filming the MV for "Rough" and appearing before on 'Mask King' on MBC radio FM4U's 'Park Kyung Lim's 2 O'Clock Date' on February 2.  

Regarding the reason she shed tears while filming the MV, Yuju relayed, "Since I was actually graduating [from school], I think I got choked up."  The MV centers on a group of friends reuniting years after high school.  She added, "I will definitely go to my graduation ceremony."

On top of that, she had previously appeared on 'Mask King' and amused everybody with how she quickly spoke on the show like she had rehearsed everything, leading to a very robotic sound.  Regarding this, she was asked, "Did you speak what you memorized?" and she replied, "Sometimes.  Seeing as how 'Mask King' was a hot variety program, the manager disciplined me.  He picked the things I would have to say no matter what at the time, but I was so nervous that I think I came off like a robot."
