If the girls come back, they must do it BIG. If 'Sexy Love' becomes a smash hit there will be no point on firing them because of bad image and controversy will be old news.
And about the Areum song, I'd love to see all of them but I also think it's great we can know her better (imagine she enters the group for nothing), she is T-ara but she wasn't tainted by the scandal so it's good for T-ara trademark
