On November 13, 2018, NCT 127 announced the release of the album's repackage, Regulate with teasers of the members.{{cite web|url=http://www.kpopherald.com/view.php?ud=201811141104072241161_2|title=NCT 127 to release repackaged album on Nov. 23|date=November 14, 2018|website=Herald|access-date=January 3, 2019|archive-date=May 19, 2019|archive-url=https://web.archive.org/web/20190519171300/http://www.kpopherald.com/view.php?ud=201811141104072241161_2|url-status=live}} The album and its lead single, "Simon Says", was released on November 23, 2018.{{cite web|url=https://entertain.naver.com/now/read?oid=076&aid=0003345279|title=NCT 127, 신곡 'Simon Says'로 파죽지세 행보 이어간다|work=Chosun|date=November 14, 2018|access-date=November 23, 2018}}{{cite magazine|url=https://www.billboard.com/articles/columns/k-town/8486338/nct-127-simon-says-video|title=Kpop NCT 127 Pay No Attention to Haters in Dramatic 'Simon Says' Video: Watch|date=November 22, 2018|magazine=Billboard|access-date=January 3, 2019|archive-date=September 24, 2020|archive-url=https://web.archive.org/web/20200924022732/https://www.billboard.com/articles/columns/k-town/8486338/nct-127-simon-says-video|url-status=live}}

The album's theme revolves around the exploration of reality and dreams. The album incorporates several genres; such as pop, dance, R&B, ballad and hip-hop.

"Regular" is described as a high-energy hip hop track with sensual Latin vibes that incorporates Spanish lyrics.{{cite magazine|url=https://www.billboard.com/articles/columns/k-town/8478863/nct-127-english-song-regular-video|title=NCT 127 Premieres First-Ever English-Language Song 'Regular': Watch the Music Video|date=October 8, 2018|magazine=Billboard|access-date=October 11, 2018|archive-date=October 11, 2018|archive-url=https://web.archive.org/web/20181011084931/https://www.billboard.com/articles/columns/k-town/8478863/nct-127-english-song-regular-video|url-status=live}} Billboard noted that unlike many Korean songs re-released by K-pop bands in other languages, the English version of "Regular" differentiates itself from the Korean version through the content of their lyrics. The Korean one addresses their current state as a group trying to make its way in the world, in contrast to the hopeful, goal-oriented swagger expressed in the English alternative. While both versions focus on money, the Korean addresses the reality of their world versus the luxurious lifestyle expressed in the English.{{cite web|url=https://www.mwave.me/en/news/news/view/NEWS2018106138/learn-korean-with-k-pop-how-are-nct-127-s-english-korean-versions-of-regular-different-?_position=8&_cnMtCtgyId=&_searchKeyWord=&_sorting=mkeDay%20desc,created%20desc|title=How Are NCT 127's English & Korean Versions of "Regular" Different?|date=October 11, 2018|website=Mwave|access-date=October 14, 2018|archive-date=October 14, 2018|archive-url=https://web.archive.org/web/20181014091624/https://www.mwave.me/en/news/news/view/NEWS2018106138/learn-korean-with-k-pop-how-are-nct-127-s-english-korean-versions-of-regular-different-?_position=8&_cnMtCtgyId=&_searchKeyWord=&_sorting=mkeDay%20desc,created%20desc|url-status=live}}

The sixth track, "Interlude: Regular to Irregular" contains the music used in the video "NCT 2018 Yearbook #1" as well as a rearranged version of a future bass composition (titled "The 7th Sense – Reverse") by Korean electronica musician Hitchhiker that was performed by the sub-unit in the 2017 Mnet Asian Music Awards. The track also contains narrations done in Korean (by new member Jungwoo), Japanese (by Yuta) and Mandarin (by Winwin), as well as a verse from the American author Edgar Allan Poe's 1849 poem, "A Dream Within a Dream" narrated by member Johnny. The eighth track, "Come Back", is a Korean version of the originally released Japanese track off their debut Japanese EP Chain. The bonus track, "Run Back 2 U", is the full version of the demo song originally titled "Bassbot" previously performed by NCT members Johnny, Taeyong, Yuta, Ten and Jaehyun and then-SM trainee Hansol in a pre-debut video under the company's pre-debut group SM Rookies in 2015.

NCT 127 kick-started promotions for the album in the U.S. with television promotions and a partnership with Apple Music.{{cite web|url=http://kpopherald.koreaherald.com/view.php?ud=201810041724436938687_2|title=NCT 127 pushes hard for American dream|date=October 4, 2018|website=Kpop Herald|access-date=October 6, 2018|archive-date=October 6, 2018|archive-url=https://web.archive.org/web/20181006154827/http://kpopherald.koreaherald.com/view.php?ud=201810041724436938687_2|url-status=live}}{{cite web|url=https://www.forbes.com/sites/caitlinkelley/2018/10/01/nct-127-set-their-sights-on-america-with-ambitious-stateside-promotions/#734a439935e4|title=NCT 127 Set Their Sights On America With Ambitious Stateside Promotions|date=October 1, 2018|website=Forbes|access-date=October 6, 2018|archive-date=October 6, 2018|archive-url=https://web.archive.org/web/20181006120058/https://www.forbes.com/sites/caitlinkelley/2018/10/01/nct-127-set-their-sights-on-america-with-ambitious-stateside-promotions/#734a439935e4|url-status=live}} They performed their new single "Regular" as well as "Cherry Bomb" on the Jimmy Kimmel Live! outdoor concert series stage on October 8, marking their U.S. television debut;{{cite web|url=http://kpopherald.koreaherald.com/view.php?ud=201809261425178006457_2&ACE_SEARCH=1|title=NCT 127 to perform on 'Jimmy Kimmel Live'|date=September 26, 2018|website=Kpop Herald|access-date=September 30, 2018|archive-date=September 30, 2018|archive-url=https://web.archive.org/web/20180930154530/http://kpopherald.koreaherald.com/view.php?ud=201809261425178006457_2&ACE_SEARCH=1|url-status=live}}{{cite magazine|url=https://www.billboard.com/articles/columns/k-town/8478939/nct-127-debut-jimmy-kimmel-live-regular-cherry-bomb|title=NCT 127 Perform 'Regular' & 'Cherry Bomb' For U.S. TV Debut on 'Jimmy Kimmel Live!'|date=October 9, 2018|magazine=Billboard|access-date=October 11, 2018|archive-date=May 12, 2019|archive-url=https://web.archive.org/web/20190512180109/https://www.billboard.com/articles/columns/k-town/8478939/nct-127-debut-jimmy-kimmel-live-regular-cherry-bomb|url-status=live}} the group also appeared at the 2018 American Music Awards.{{cite web|url=https://www.mwave.me/en/news/news/view/NEWS2018106084/watch-nct-127-live-on-the-american-music-awards-red-carpet?_position=32&_cnMtCtgyId=&_searchKeyWord=&_sorting=mkeDay%20desc,created%20desc|title=Watch NCT 127 Live on The American Music Awards Red Carpet|date=October 9, 2018|website=Mwave|access-date=October 14, 2018|archive-date=October 14, 2018|archive-url=https://web.archive.org/web/20181014091425/https://www.mwave.me/en/news/news/view/NEWS2018106084/watch-nct-127-live-on-the-american-music-awards-red-carpet?_position=32&_cnMtCtgyId=&_searchKeyWord=&_sorting=mkeDay%20desc,created%20desc|url-status=live}}
