Euphoria was released in four editions: Regular Edition, Limited Editions A and B, and a fan club-only Boice Limited Edition. It went on to debut at number two on the weekly Oricon Albums Chart. The band embarked on the CNBLUE 5th Anniversary Arena Tour 2016 "Our Glory Days" throughout November in Chiba, Osaka, Aichi, Fukuoka, and Tokyo.

Background
CNBLUE announced Euphoria as its fifth studio album on the September 5, 2016 broadcast of Abema TV's Fresh!, with a release date of October 19. The date marks the five-year anniversary since the band's major-label debut in Japan with "In My Head". The album serves as the gratitude the band holds for its fans since then.

Music structure
In "Glory Days", CNBLUE expresses gratitude towards its fans. The lyrics encourage one to "keep going on despite being lost on the path". Dealing with the future, "Take Me Higher" conveys the band's sentiment of exceeding its potential. Drummer Kang Min-hyuk described "Face to Face" as "good rhythmic song" and compared it to previously released songs "With Me" (Code Name Blue) and "Don't Care" (What Turns You On?). "Puzzle" is a wedding-themed song that revolves around "eternal love". "Royal Rumble" compromises a "rhythmical tone" and deals with "the next stop" for the band. The song revolves around the battle royals depicted in the professional wrestling organization WWE. Frontman Jung Yong-hwa described it as a general idea, in which he remarked, "anyone has to keep fighting, right?". Similar to "Daisy" (Colors), "Stay with Me" shows the band's thankfulness to its fans.

In an interview with EMTG Music, the interviewer noted the positivity in the Euphoria singles, in contrast to singles released in the years prior which dealt with "conflicts and anxiety". In response, Jung stated: "When you listen to positive music, it makes you feel good, right? Now I wish more that you would listen to our music and become happy. Before, when something doesn’t work out the way I want, I would turn that into a song. Now, it also plays a big part that I have a very happy environment when making music."
