LUMIEL Members Profile 2026: Ages, Facts & Pre-Debut Details
LUMIEL is a pre-debut South Korean girl group under HEADAM. Its publicly revealed lineup currently includes Byeoljji and Hyojung, while the agency plans to recruit two additional global members. A debut date has not yet been announced, although the group is expected to release a single album.
At present, LUMIEL does not have an officially announced debut date, publicly confirmed fandom name, or documented group discography. The group is expected to release a single album, but the timing has not been announced in the sources reviewed for this article.
That makes LUMIEL different from established K-pop acts with long discographies and extensive media coverage. Much of the group’s story is still being formed. For readers searching for LUMIEL members, the most reliable information currently centers on the two revealed members, their backgrounds, and the group’s pre-debut plans.

Who Is LUMIEL?
LUMIEL (루미엘) is an upcoming South Korean girl group under HEADAM. The group is currently in its pre-debut stage and is publicly documented with two members: Byeoljji (별찌) and Hyojung (효정). According to the current group profile, HEADAM intends to recruit two additional global members, meaning the lineup may expand before the official debut.
The group name, agency, current lineup and plans for additional global members are documented by KProfiles. The source also lists HEADAM’s public Instagram, Threads and YouTube accounts.
LUMIEL Members at a Glance

| Byeoljji | January 3, 2001 | 25 | Main Dancer, Sub Rapper | Korean |

The positions are specifically documented on the current LUMIEL profile, which notes that the positions were confirmed through an Instagram post.
LUMIEL Group History
Formation and Pre-Debut Stage
LUMIEL is still a pre-debut project, so there is no lengthy public formation history comparable with established idol groups.
The information currently available shows that HEADAM introduced a two-member public lineup consisting of Byeoljji and Hyojung. The group is expected to grow before debut, with the company planning to recruit two additional global members. That means the current two-member lineup should not automatically be treated as the final formation.
The decision to seek global members is particularly notable because it indicates that the agency is considering an international component during the group’s formation rather than waiting until after debut to expand overseas activities. However, there is not enough publicly available information to determine the nationalities, roles or identities of those future members.
Current Pre-Debut Lineup
Byeoljji and Hyojung are the two members publicly identified at present. Byeoljji brings an unusually long pre-debut performance history, including participation in several earlier projects and dance activities. Hyojung’s documented background includes practical dance training and membership in the dance team HERIUN.
Official Debut
LUMIEL has not yet received a publicly confirmed debut date in the sources reviewed.
The group is expected to release a single album, but there is no verified release date or confirmed title available at this time. It would therefore be inaccurate to describe LUMIEL as having officially debuted.
What Could Change Before Debut?
Because the group remains pre-debut, several details may still change.
The final number of members is not necessarily fixed. HEADAM’s stated plan to recruit two more global members would potentially bring the lineup to four. Positions could also be expanded once the additional members are introduced.
There is also no verified group-level information yet about a leader, main vocal structure, official concept, fandom identity, debut song title, album track list or official lightstick.
For that reason, this profile treats LUMIEL as an announced/pre-debut group, rather than filling the page with projected details.
LUMIEL Agency: HEADAM
LUMIEL is under HEADAM, the company identified by the group’s current profile as its agency. HEADAM’s publicly linked social channels include Instagram (@headament), Threads (@headament), and YouTube (@HEADAMTV).
Public information about HEADAM’s broader idol-management structure is limited in the sources reviewed. There is not enough reliable evidence to describe a larger parent company, major subsidiary structure, contract terms or corporate expansion without risking speculation.
That lack of information is worth noting because small and emerging entertainment companies often reveal their artist-management plans through social media rather than maintaining the same level of public documentation available from major agencies.
For LUMIEL, the agency’s public social activity is therefore an important reference point for future announcements.

Members Profile
1. Byeoljji Profile
Stage Name: Byeoljji (별찌)
Birth Name: Kim Byeoljji (김별찌)
Date of Birth: January 3, 2001
Age: 25 as of September 14, 2026
Zodiac Sign: Capricorn
Chinese Zodiac: Snake
Height: 163 cm
Weight: 44 kg
Blood Type: Not publicly available in the current LUMIEL profile
MBTI: ENTJ
Nationality: Korean
LUMIEL Position: Main Dancer, Sub Rapper
Representative Color: Watermelon Pink (#FF6BB8)
Byeoljji’s Role in LUMIEL
Byeoljji is the older member of the currently announced LUMIEL lineup, and her officially listed responsibilities are main dancer and sub rapper. Those positions give her a performance-focused role within the pre-debut team.
Her background is considerably more extensive than the short history of LUMIEL itself. Before joining the project, Byeoljji was associated with several girl-group and performance projects, including MIDNIGHT, WeGirls, N:Dear and BERRYZ, as well as the dance team ZERO. She also became a member of Astell, a four-member girl group that debuted in July 2024.
That history gives her a level of pre-debut and group experience that is unusual for an idol who is now appearing in another new project.
Earlier Career
Byeoljji was first known publicly through MIDNIGHT, where she was revealed in 2018. MIDNIGHT did not ultimately debut and the project was dissolved before an official debut. Later, she joined We Girls in 2021. She subsequently became associated with Ndear, the ZERO dance team and BERRYZ before moving into Astell.
Her history has included both idol-group projects and dance-based performance work. KProfiles records her membership in the ZERO dance team and notes that she was involved with the Korea Street Hip Hop Association and led the TMZ hip-hop dance class.
Astell and Other Activities
Byeoljji became a member of Astell, which debuted on July 9, 2024 with the digital single “Island.” Astell was originally under Errday and later became associated with Midas Entertainment after its members moved to new contracts following the end of their earlier agreements.
Kpopping also lists Byeoljji as a singer, rapper and dancer and records her involvement with Astell and We Girls, alongside earlier associations with other projects.
This background matters when looking at LUMIEL because it means Byeoljji is not entering the pre-debut system without prior experience. She has already worked through several group projects and dance environments.
Television and Performance Background
Byeoljji appeared in the drama Suits and the KBS 2TV children’s reality program Who’s the Best Singer? (누가 누가 잘하나) in 2018. These appearances predate her LUMIEL activities.
She has also been associated with lyric writing. Sources covering her earlier MIDNIGHT period report that she participated in writing lyrics for songs connected with that project.
Personal Information
Her publicly listed basic information includes her January 3, 2001 birthday, Capricorn zodiac sign, Korean nationality, 163 cm height, 44 kg weight and ENTJ MBTI.
Some older profile sources contain conflicting information about specific details, including aspects of her earlier profiles. For the current LUMIEL profile, the January 3, 2001 birth date is the figure used here because it is the date currently listed in the group’s latest profile and is also supported by other idol databases.
Family and Relationships
Detailed family information about Byeoljji is not publicly available in a sufficiently reliable form for inclusion here.
There is also no publicly confirmed relationship information that should be presented as fact. Dating rumors and fan speculation have not been used in this profile.
Net Worth
Byeoljji’s exact net worth is not publicly available.
Her known professional activity has included group performances, dance, music, television appearances and idol-related work, but there is no reliable public financial disclosure that would allow an accurate personal wealth figure.
Official Social Media
The current LUMIEL profile links Byeoljji to these accounts:
- Instagram: @byeol_____jji_
- Threads: @byeol_____jji_
- TikTok: @byeol_jji_
- X: @Byeol_jji__ — listed as inactive
Why Byeoljji Matters to LUMIEL
For an upcoming group, experience can be as important as age or position. Byeoljji enters LUMIEL with several years of exposure to dance, pre-debut projects, idol groups and performance-related work. Her main-dancer and sub-rapper roles also give the current lineup a clear performance anchor.
2. Hyojung Profile
Stage Name: Hyojung (효정)
Birth Name: Lee Hyojung (이효정)
Date of Birth: August 30, 2005
Age: 21 as of September 14, 2026
Zodiac Sign: Virgo
Chinese Zodiac: Rooster
Height: Not publicly available
Weight: Not publicly available
Blood Type: Not publicly available
MBTI: INTP
Nationality: Korean
LUMIEL Position: Lead Vocalist, Maknae
Representative Color: Mimi Pink (#FFD1E6)
Hyojung’s Place in the Group
Hyojung is currently the youngest member and lead vocalist of LUMIEL. As the maknae, she is the youngest of the publicly revealed lineup, while her lead-vocal role suggests that vocals will be a central part of her contribution.
The available information about Hyojung is much more limited than the record surrounding Byeoljji. This is normal for a pre-debut artist who has not yet appeared in a major public promotional cycle.
Rather than filling in missing details with low-quality profile information, the verified public record gives us a smaller but clearer picture.
Dance Background
Hyojung was a member of the dance team HERIUN. The current LUMIEL profile also states that she was close to S2IT’s Haru because they were both part of HERIUN.
Her involvement in a dance team is notable because it means her pre-debut background is not limited to formal idol training. It connects her to a performance environment in which choreography and stage skills are important.
Education
Hyojung attends the Paekche Institute of the Arts, where she is in the Department of Practical Dance, according to the latest profile available.
This is one of the clearer pieces of educational information publicly attached to her profile and helps explain why dance appears to be part of her development as a performer.
Personality Information
Her current public profile lists INTP as her MBTI type. It also identifies her charm points as her clear vocals and warm smile, while running is listed as one of her hobbies.
These details should be understood as profile information rather than a scientific or permanent description of her personality.
Personal Information
Hyojung was born on August 30, 2005, making her 21 years old as of September 14, 2026. Her zodiac sign is Virgo and her Chinese zodiac sign is Rooster. She is listed as Korean.
Her height, weight and blood type are not provided in the current LUMIEL profile, so those values are not treated as verified.
Family and Relationships
Detailed family information is not publicly available.
There is also no publicly confirmed relationship information that should be presented as fact. No rumors or fan theories have been included.
Net Worth
Hyojung’s exact net worth is not publicly available.
As LUMIEL is still pre-debut, there is no reliable public financial information that would justify an earnings or wealth estimate.
Social Media
The current LUMIEL profile lists:
- Instagram: @swafairy
- Instagram: @2hfairy
- Threads accounts associated with those names
- YouTube: @쬬누 JJYONU
Because the group is still forming, readers should rely on agency-linked and member-linked accounts for future official announcements rather than fan-created pages.
Why Hyojung Matters to LUMIEL
Hyojung provides a younger vocal and dance profile to the current lineup. Her practical-dance education and HERIUN background complement Byeoljji’s more extensive idol and dance history.
The exact balance between vocals, rap and performance may become clearer once the additional global members are revealed.
LUMIEL’s Current Lineup and Member Dynamics
The two publicly documented members already represent different stages of performance experience.
Byeoljji is older, has prior experience with several idol projects and has been consistently associated with dance, rap and stage performance. Hyojung, meanwhile, is younger and is positioned as a lead vocalist and the group’s maknae while also having a practical-dance background.
Because two additional global members are expected, however, it would be premature to define LUMIEL’s final group chemistry.
The future members could significantly change the team’s vocal distribution, rap line, dance balance and international identity.
LUMIEL’s Musical Identity
There is currently not enough officially released music to make a reliable assessment of LUMIEL’s established musical identity.
No official debut song, EP, studio album, concept album or group-level genre has been publicly confirmed in the material reviewed.
Therefore, it would be misleading to label the group definitively as synth-pop, hip-hop, R&B, dance-pop or another particular genre simply because those styles are common in contemporary K-pop.
The strongest factual description at this stage is:
LUMIEL is a pre-debut girl group whose music direction has not yet been publicly established.
Once the debut single is released, questions about vocal color, production style, lyrical themes and performance concept can be evaluated through the actual recordings and official credits.
LUMIEL Discography
Because LUMIEL has not officially debuted, there is currently no verified group discography.
Studio Albums
| Release | Date | Status |
|---|---|---|
| None | — | No studio album announced |
EPs / Mini Albums
No verified EP or mini album has been announced.
Singles
The group is reportedly planning a single album, but its title and release date are not publicly confirmed.
Japanese Releases
None publicly announced.
Notable Songs
LUMIEL does not yet have an officially released group song that can be evaluated as a signature track.
LUMIEL Awards and Achievements
LUMIEL has not yet debuted, so the group has no verified music-show wins or major award results.
| Year | Award / Achievement | Work | Result |
|---|---|---|---|
| — | No official group awards | — | Not applicable |
It would also be inappropriate to attribute Byeoljji’s earlier career achievements to LUMIEL itself. Her previous activities belong to her individual career and earlier groups.
LUMIEL Tours and Concerts
There are currently no verified LUMIEL world tours, Asia tours, Japanese tours or headline concerts.
Pre-debut showcases or future promotional events should not be presented as confirmed until announced by HEADAM or another authoritative source.
LUMIEL Brand Endorsements and Partnerships
No verified group-level brand ambassador appointment or major endorsement has been publicly established.
| Year | Brand | Member/Group | Role |
|---|---|---|---|
| — | No verified partnership | — | — |
LUMIEL Social Media Presence
The group profile currently points readers toward the agency’s public social channels.
| Platform | Official Account |
|---|---|
| @headament | |
| Threads | @headament |
| YouTube | @HEADAMTV |
| X / Twitter | Not publicly confirmed |
| TikTok | Not publicly confirmed |
| Weverse | Not publicly confirmed |
| Official Website | Not publicly confirmed |
For a pre-debut group, the agency’s social channels are particularly important because lineup announcements, teaser images and debut scheduling may appear there before being covered by larger entertainment publications.
LUMIEL Revenue Sources
Because LUMIEL is not yet officially debuted, there are no reliable public figures for group income.
After debut, potential revenue categories could include:
Music: Digital and physical music sales.
Streaming: Revenue associated with official audio and video platforms.
Concerts: Ticketing and live-event revenue once performances begin.
Merchandise: Official goods, albums and collectibles.
Endorsements: Brand campaigns, advertising and ambassador work.
Content: Official video content and other monetized media activity.
These are standard potential revenue categories, not claims about LUMIEL’s present earnings. No verified income or net-worth figures have been published for the group.

The public information currently establishes two members, an agency, planned recruitment of two additional global members and an intention to release a single album. The missing debut date and unfinished lineup are the most important reasons to avoid presenting the group as fully established.
For fans tracking LUMIEL, the next meaningful developments will likely be the introduction of additional members, confirmation of the final lineup, debut scheduling, concept material and the first official music release.
Conclusion
Byeoljji brings considerable previous performance and idol-project experience, while Hyojung is the younger lead vocalist with a documented practical-dance background.
LUMIEL is an upcoming South Korean girl group under HEADAM that is still building its final identity before debut. The current public lineup consists of Byeoljji and Hyojung, with two additional global members planned.
Because the group’s debut date, final lineup, music and fandom identity have not yet been fully announced, the most accurate way to understand LUMIEL right now is as a pre-debut project with an evolving lineup. Future official announcements from HEADAM will be important for confirming the group’s final direction.
