On KBS COOL FM's 'Kim C's Music Show', Lee Hyori commented, "Lately, I feel the best when people tell me they find strength after hearing one of my songs. I'm the most thankful when they understand me. Before, I wanted to show off a lot of things, but now I want to talk about a lot of things. So I put all that in my album."

Since her new song's title is "Bad Girls", radio host Kim C asked her, "Is Lee Hyori a bad girl? Are you bad at your core?" Lee Hyori answered wisely, "I don't think I'm a bad girl, but that people call women like me bad girls. Since I do a lot of volunteer work compared to before, people say, 'Lee Hyori's become nice' or 'She's not like before.' But to be honest, in certain respects I've become more of a 'Bad Girl' than I was before."
