Group S showed an unchanged harmony on Mnet "M! Countdown."

On October 23, S performed to their songs, "Into The World" and "Everything You Want To Do."

They performed the song, "Into The World" in front of mic stands in suits. Their collaboration is a continuation from 11 years ago when they made a hit with "I Swear."

For their stage, "Without You," Kangta played the piano while singing the song. The emotional touch blended three voices into one.

Their title song, "Without You" is a pop ballad about the feelings and after effect of a breakup.
