HyunA and Highlight's Dongwoon talked about their long friendship.
The August 13 episode of 'School Attack' welcomed Triple H as the guest. Before welcoming the artist, MC Dongwoon revealed, "I've known her (HyunA) for 13 years. I'm 28 right now so I've known her for about half of my life." MC Eun Ji Won asked, "Do you still keep in contact with her?" Dongwoon brought laughter as he replied, "I actually don't know her number."
Triple H came into the room, and HyunA shared, "I've seen (Dongwoon) oppa since I was in 5th grade. He still has the good boy image." Dongwoon also said, "HyunA was full of ambition since then. She was the type that speaks her mind."
