Boy group BTS performed boldly on stage.

On October 23 of Mnet "M! Countdown," BTS performed their new song, "War of Hormone" for the first time.

After the beat began, each member came onstage and posed. With addictive melody and upbeat dance moves, the members' free gestures and strong choreography stood out.

On this day, Dynamic Duo Gaeko took first place with his song, "No Make Up," and group S and Super Junior made comeback stages.
