This nostalgic song blurs alternative hip-hop sound with acoustic guitar and synth-pop. The lyrics offer comfort in a time when the world faces the pandemic.

The story behind the song begins from BTS declaring that “even in the face of this new normality, our life goes on and imparts a message of healing to fans and to the world.”

The theme “life goes on” was mentioned several times while BTS shared the process behind the album through vlogs over the months.

“Life goes on, let’s live on” was also the main message of their speech at the 75th UN General Assembly, given just a few months before the song release. The group appeared there as they’ve worked previously with UNICEF on the “LOVE MYSELF” campaign, this time giving the message of “let’s live on in a new world, breaking free from despair and supporting one another in warm solidarity.”

The song serves as the leading track and the second promotional single from BTS' fifth studio album, BE.

The single was announced by BigHit Entertainment via their official SNS and Weverse accounts on October 30, 2020.

The live debut stage took place during the American Music Awards on November 22, 2020.
