Choi Yena revealed that the full-body suit and stage concept she used at the recent Waterbomb Busan festival were her own ideas. In a preview shown at the end of MBC's “Omniscient Interfering View” on September 12, her manager explained that Yena routinely prepares her own ideas for meetings about award shows and encore concerts and had planned the Waterbomb styling in the same way. Yena said she wants to check every detail so she can perform without regrets and enjoy the stage to the fullest. At Waterbomb, she combined a suit covering her whole body with a high ponytail and goggle-like sunglasses, creating the look of a comic-book hero. The choice drew online attention for emphasizing her own character and concept instead of revealing clothing.
