On March 4, Red Velvet (except Joy) visited the entrance ceremony for Seoul Arts College as the guest performers. The girl group performed several of their hit tracks and among them was "Dumb Dumb."

Red Velvet dominated the stage with their stellar vocals and dance, but they ran across an issue as the music suddenly came to a stop. At first, the girls looked very startled and confused, but they did not let the audio issue ruin their performance.

The girls quickly got back on track and finished their stage with much professionalism, receiving a great applause at the end.
