The second track is a dance pop song with addictive repetition of synth bass themes and restrained, matte drum beats that add a sexy yet mysterious groove. This song, which reinterprets early 2000s pop music in ZEROBASEONE's own style, expresses 'an intense attraction that you can't resist even though you know it's bad' with the mystery thriller concept of 'hide-and-seek with the devil.'
