In an interview, the composer said he was curious about the new idol group's debut with the song and that a foreign reaction would be good. On the last day of the SM songwriting camp, a composer put out a beat, which came out very well, and eight or nine composers made it. Taeyong and Mark participated in rap making. The lyrics introduce the NCT score keyword, "Seventh Sense," which means a sense of feeling and understanding each other's dreams through music. It contains NCT's desire and aspiration to communicate powerfully with the public in the future.[2]
