The girls had a photoshoot with the fashion magazine, and they were asked how they felt about reaching their 6th year since debut. The girls said, "We still feel like rookies, so we don't know how to act when hoobaes greet us at music shows. We think that since we have so many hoobaes now, we should be more responsible. Each year is different. We learn something new every day."
