The lyrics speak from Taeyeon's point of view on being a celebrity and, in the singer's own words, "about being yourself in a freer way, while moving on from hard and frustrating times". The singer has also said that she wanted the song to express a "Music is my life" feeling. Music video The music video was filmed in Auckland, New Zealand and employed nature scenery as the backdrop.
