ONF, who even appeared on M Countdown

Following their appearance on Show! Champion, ONF went on to appear on M Countdown and spread their uninhibited "Open the Door" performance.
They made a strong impression with a high-quality performance.
It was ONF, who showcased energetic and precise choreography set to an uninhibited rock sound.
They made the stage even richer by showing off solid vocal skills.
Looking at the photo, I can feel the energy of that day again.
