"Just One Day" will be the follow-up song from their second mini-album 'Skool Luv Affair' and it's the work of Rap Monster, SUGA, and j-hope.

Their agency Big Hit Entertainment revealed to fans, "Their album's title track 'Boy In Luv' received much more love than we expected. With a thankful heart to fans, we decided to conduct follow-up promotions. Rather than a powerful choreography, the choreography this time around focuses mainly on the feel of the song. Please look forward to another side of BTS."

The boys will kick off their follow-up promotions on 'Show Champion' on the 9th!
