Marmello were a K-Pop group with a twist - they played their own instruments. They were a bona fide band. Although they disbanded in 2019, we hope for a comeback, which isn't unprecedented in the K-Pop world - because they actually rocked kind of hard for a K-Pop group. I mean, this ain't metal - it's pop-rock - but it's not usual to see.
Less than three weeks after this single was released, the band reimagined the song, slightly changing the lyrics and title to be a rally song for the 2018 World Cup. It rocks just a little harder.
