On the February 24 episode of 'Music Bank', Red Velvet performed their new hit "Rookie". The girls impressed once again with their lovely performance. However, Seulgi's voice couldn't be heard as the mic failed to work.
Despite the mic's malfunction, Seulgi carried on with professionalism. A staff member brought a handheld mic in the middle of the performance and Seulgi took over as if nothing happened.
