Two earlier trainees, Lee Soo Min and Takeuchi Miyu, were part of the pre-debut period but did not make the final line-up.

Sheon joined in November 2021, completing the seven-member group. As the first girl group from a label known for acclaimed songwriters and producers, Billlie drew attention before it released a single track.

Career

Billlie debuted on November 10, 2021, with The Billage of Perception: Chapter One and the lead single “Ring X Ring”, which introduced the story of a girl who disappeared in a village on a day of purple rain. The fandom took the name Belllie’ve, and the group followed up with the digital single “Snowy Night” in December 2021.

The Collective Soul and Unconscious: Chapter One arrived in February 2022, and its track “GingaMingaYo (the strange world)” became the song that carried the group to an international audience. In August 2022 the group released The Billage of Perception: Chapter Two, led by “Ring Ma Bell (What a Wonderful World)”, and collaborated with Yoon Jong-shin on the track “Patbingsu”. The group won the Potential Award at the Asia Artist Awards in 2022.

The Billage of Perception: Chapter Three followed in March 2023, giving the group its first music show win in April and a nomination for Best K-Pop Album at the 21st Korean Music Awards. Activities were halted later that month after the death of Moon Sua’s brother Moonbin of Astro, and Moon Sua stepped away from the group. Suhyeon went on hiatus in June 2023, and the remaining five members returned with the single album Side-B: Memoirs of Echo Unseen in the autumn.

Japan became a second base for the group through Victor Entertainment. A Japanese version of “GingaMingaYo” came out in May 2023, followed by the album Knock-on Effect in February 2024.

Moon Sua and Suhyeon resumed activities in April 2024, and the group won Best Performance at the Seoul Music Awards that year after taking Female Idol Rising Star at the Korea First Brand Awards in 2023. Teen Vogue also named Billlie among its girl groups to watch.

The EP Appendix: Of All We Have Lost landed in October 2024 with the lead single “Remembrance Candy”, written by IU, and the pre-release track “Trampoline”. In April 2025, Moon Sua and Siyoon debuted as the group’s first sub-unit with the single “Snap”, featuring Sokodomo. Siyoon later joined the cast of the film Perfect Girl, her first screen role.

Billlie returned at full strength in 2026 with the pre-release single “Cloud Palace (False Awakening)” in January, followed by its first full-length album, The Collective Soul and Unconscious: Chapter Two, on May 6.
