Background and release
Super Junior's album Play and a special edition subtitled (Pause version) was released on November 6, and November 28, 2017, respectively. SM Entertainment announced that the album's repackage edition Replay would be released on April 12, 2018 to complete the trilogy. The album's title track was described as a unique concept that is "180 degrees opposite" to the band's usual musical style. A teaser image was released on March 27, 2018, and it was announced new tracks "Lo Siento", "Me & U", "Super Duper" and "Hug" would be included on the repackaged album. It was also confirmed "Lo Siento", a Latin-pop song, would be the lead single. The single included only seven of the eleven members of Super Junior;Leeteuk, Heechul, Yesung, Shindong, Eunhyuk, Siwon and Donghae. Other band members did not participate for various reasons; Kyuhyun and Ryeowook were carrying out their mandatory military service while Kangin and Sungmin were on hiatus. Although Heechul appeared in the teaser image, Label SJ announced he would not participate in the album's promotion because of health issues. In a separate interview, Heechul said he had been having difficulties performing on stage since the release of "Sorry, Sorry" (2009) due to a leg injury. The song's release also marked Siwon's return to the band's line-up.

The single is the band's first collaboration with foreign artists; it was produced by Play-N-Skillz and features Dominican-American singer Leslie Grace. It is also the first collaboration between a Latin artist and K-pop band. Grace's part in the collaboration came from the recommendation of Play-N-Skillz. According to Grace:

"They didn't know me, they were looking for a female voice that would fit this idea of doing a trilingual song in Korean, English and Spanish and the producers of the song are friends of mine and they said 'we know a girl who could fit', and that's how I came."

In another interview, Grace praised Super Junior's approach to the collaboration, saying the band were "open to learning about [Latin] culture, and why we use certain sounds". On April 6, 2018, it was announced a special version of "Lo Siento" featuring Kard would be released on the digital download version of Replay, and that Somin and Jiwoo of Kard would join Super Junior's promotion of the song in South Korean music programs. In October 2018, Super Junior released a remixed version of the song titled "Lo Siento (Play-N-Skillz Remix ver.) (Feat. Leslie Grace)" as the fifth track on their Latin-pop EP One More Time.
