Background and release
On July 16, 2012, SM Entertainment announced that BoA will be coming back with her seventh Korean album titled Only One, two years after the release of her sixth album Hurricane Venus. For the choreography of her title track, "Only One", she enlisted the help of Nappytabs who also contributed on the choreography on her upcoming dance flick Make Your Move 3D. SM Entertainment also announced that BoA will be promoting the album via her own comeback show BoA 4354. The number represents the days BoA has been in the entertainment industry.

The album has two editions: regular and limited. Along with the album, fans can order different bundles that come with a photobook and/or poster. The limited edition of the release included a special packaging containing a 48-page photobook, while the regular edition contained a 24-page photobook. In 2013, BoA re-recorded the title track and "The Shadow" in Japanese and released it as her 32nd single titled under Avex Trax on February 27, 2013. The single peaked at number ten on the Oricon Singles Chart while the Japanese recording of "Only One" reached number eight on the Billboard Japan Hot 100. The original album became available in the Philippines on July 5, 2013.

Development and composition
The Korea Times noted that the record served as "a departure from the sleek, fast-paced and beat-heavy dance music she has become synonymous with", particularly from her previous albums BoA (2009), Identity (2010) and Hurricane Venus (2010). BoA elaborated that the creative process behind the record was to produce a relaxing and "comforting" album that could resonate with the general public, even if they were not necessarily fans of her. She acknowledged that even though electronic music styles remained trendy at the time, her personal preference for Only One nonetheless leaned towards a more "relaxed" and easygoing aesthetic. Although the album did not contain large amounts of electronic elements, BoA intended to craft the album's composition to appeal to those who still appreciated her electronic style, similar to what she showcased in Hurricane Venus.
