After the two performed her hit song "Shake That Brass," Amber said in the interview portion, "It was a dream-like stage.  She's my best friend and we've never performed together before.  I still can't believe it," while Ailee said, "I thought this friend would match me well.  She has crazy, energetic blood in her veins."

Amber admitted, "These days, I want to date.  I've gained a lot of interest in men." Ailee added, "We talk about men a lot.  Amber tells me she's lonely and wants to have a boyfriend," to which Amber said, "It's different from [having] friends.  I want to date a bit."

MC Yoo Hee Yeol asked if she ever had a boyfriend.  Amber responded, "I did.  I had just one.  A really long time ago.  I really like being somewhat active, so I wish I had a boyfriend with whom I could play sports with.  I like basketball, skateboarding, everything."
