The first pressing of the physical release comes with a DVD featuring the song's music video and making-of, as well as an alternate cover artwork.

The single includes a previously unreleased cover of The Outsiders theme song "Stay Gold" by Stevie Wonder, which Misia recorded for the soundtrack of the drama series Hatsukoi (2012),[5] and a live rendition of the Bette Midler song "The Rose", recorded at the Misia Candle Night 2012 concert held at the Kawaguchiko Stellar Threater on August 26, 2012.

"Back in Love Again" is written in the key of A major and set to a common time tempo of 70 beats per minute.

[3] Hotei received acclaim for the "dignified elegance" of his composition and for providing Misia's catalogue with a "fresh and exciting" type of ballad.

[1] Shindō and Nakane pulled inspiration from this first impression and decided on carnations specifically because its associated hanakotoba most matched the spirit of the song.
