History

2022: Introduction, debut with 'Sequence: 7272' and 'Sequence: 17&'

On July 11, 2022, A2Z Entertainment (formerly Pop Music) announced that they would be debuting their first girl group. The members were revealed through trailers on July 11 and July 12. On July 12, the group's management company announced that the septet would be releasing their debut extended play Sequence: 7272 on July 28. The music video for their debut lead single "Pop? Pop!" was released one day prior to the album's release, and the press showcase was also held at Mastercard Hall in Yongsan-gu, Seoul on the afternoon of the 27th. The album was officially released on July 28. The group made their broadcast debut on Mnet's M Countdown on July 28 to perform "Pop? Pop!".

On November 17, the group released their first single album titled Sequence: 17&, with its lead single "♡Ticon" (pronounced "love-ticon"). With this release, CSR earned their first music show win on KBS's Music Bank on December 2.

2023: 'Delight', leader switch and 'HBD To You (Midnight Ver.)'

CSR released their Korean second extended play Delight, with its lead single "Shining Bright", on March 29, 2023. On July 27, the leader of CSR was switched from Sua to Duna, as the group has rotational leaders for every anniversary.

The group released a special digital single "HBD To You (Midnight Ver.)" on November 26, as commemoration of the first anniversary of the group's fandom, Maeum. On December 22, it was announced that the group would be active as a trio (Sihyeon, Yuna, Sua) for the time being, as the remaining four members were in an overseas schedule.

2024: Chuang Asia: Thailand, L'heure Bleue: Prologue and Japan debut

On January 15, 2024, it was announced that members Geumhee, Seoyeon, Duna and Yeham would be participating in the survival show Produce Camp Asia: Thailand (or Chuang Asia). On March 2, Seoyeon, Yeham and Geumhee were eliminated in the first elimination round in episode 5, finishing in 53rd, 57th and 59th place respectively. On April 6, Duna was eliminated in the final episode, finishing 14th overall with 25,093,428 points, thus being unable to debut with Gen1es.

The group released their second single album L'heure Bleue: Prologue on June 11, with its lead single "Pretty Mob". This marked a year and 3 months after their previous comeback. In addition, the group released their first Japanese extended play, titled L'heure Bleue, on July 3, and held a 5-stop Japan tour from June 29 to July 19.
