She continued, "I definitely believe that we'll all get back together. We said in 5 years in both joking and serious manner but that 5 years is desperately desired. We, as well as fans, want it to happen. I believe our members will be shining in 5 years and I hope we each can be at a position where we can say, 'I'll be right back'. I really hope that we can get back together."
