Group BTS, who gained popularity with song "Boy in Luv", will continue their album promotion with "Just One Day".

"Just One Day" is included in BTS' February album Skool Luv Affair, featuring collaboration of Rap Monster, SUGA, and j-hope.

"Just One Day" is an urban hip-hop song that carries sweet lyrics of the desire to hold hands with one's lover.

BTS revealed a wild charm with "Boy in Luv"; "Just One Day" will show BTS' boyish innocence.

Big Hit Entertainment stated: "Title song 'Boy in Luv' received more praise than expected; we decided to repay fans' love by promoting 'Just One Day' as well. Because the song is a sweeter song, the choreography will be much more relaxed, leaving room for emotional expression. Please support the new song!"

Meanwhile, BTS stages the first performance of "Just One Day" on MBC "Show! Champion" on April 9.
