Recently at a press conference for the concert, the group talked about the concept for their new album and title track "Run," revealing that once again, emotions of youth is once again their focus.

"Part one explained how youth is tiring and difficult, and it also touched on how we feel like we're always on edge. Part two will have a more adventurous and daring feel to it. That's why our title song is 'Run'," said the group (via Soompi).

Rap Monster went on to explain how they tried to be the most authentic they could be with their new release.

"We didn't want to just blankly say 'cheer up' or 'be strong.' We really wanted to comfort people our way, by producing the music and writing the lyrics ourselves. We poured our heart and soul into this amazing song," said Rap Monster.
