Ablume Members Profile 2026: Bio, Age, Birthday & Interesting Facts
ablume Members Profile 2026 introduces one of the most closely followed new chapters connected to the recent history of K-pop. ablume is a three-member South Korean girl group made up of Saena, Sio and Aran, all formerly of FIFTY FIFTY. The trio officially introduced ablume in October 2024 after signing with MASSIVE E&C and later made their debut with “Echo” in May 2025.
The group name comes from the German word “Blume,” meaning flower, and was chosen to represent growth, change and the process of blooming. The members have repeatedly connected the name with finding their individual colors and bringing those colors together through music.
ablume is particularly notable because all three members already had international exposure before their redebut. As members of FIFTY FIFTY, Saena, Sio and Aran were part of the original lineup behind “Cupid.” The song became a major international K-pop hit and reached No. 17 on the Billboard Hot 100.
Their story then took a very different direction because of a prolonged contract dispute involving FIFTY FIFTY’s former agency, ATTRAKT. In 2023, the three members pursued legal action and subsequently left the agency. In August 2024, they signed with MASSIVE E&C and began preparations for a new group.
Today, ablume remains a three-member group. The group’s official website continues to feature its “Echo” era and official videos, while an April 2026 report said the company planned a full-length album aimed at the global market within 2026. As of September 22, 2026, that planned album has not appeared in the group’s official online discography.

Who Is ablume?
ablume is a three-member K-pop girl group consisting of Saena, Sio and Aran. The three artists had previously debuted together in FIFTY FIFTY before establishing a new identity under MASSIVE E&C. The new group was formally announced on October 15, 2024.
The concept behind ablume is closely linked to renewal. On its official website, the group describes its music around themes including healing, trust, friendship and beginning again. The members have also explained in interviews that they wanted their new identity to represent continued artistic development rather than simply repeat their past.
Their debut release, “Echo,” was designed around that idea. The song was released together with “Never Far Away (Prologue)”, a piano-led ballad that the official site describes as part of the emotional foundation of the group’s return.
Group History
Formation and Pre-Debut
Saena, Sio and Aran already had an established professional history before ablume existed.
The three members debuted in FIFTY FIFTY in November 2022. Saena, Sio, Aran and Keena formed the original four-member lineup. FIFTY FIFTY’s second major release cycle produced “Cupid,” which became a breakthrough hit outside Korea.
In March 2023, “Cupid” entered the Billboard Hot 100 at No. 100. It later climbed to No. 17, giving FIFTY FIFTY an important place in the history of K-pop’s international chart performance.
That rapid rise was followed by a contract dispute involving the members and ATTRAKT. After the legal conflict, Keena returned to ATTRAKT, while Saena, Sio and Aran eventually moved forward separately. Their exclusive contracts with ATTRAKT were terminated in October 2023, according to reporting at the time.
On August 12, 2024, the three signed exclusive contracts with MASSIVE E&C. The new agency then announced that they would operate as a new group.
Official Group Announcement
On October 15, 2024, MASSIVE E&C announced the creation of ablume.
The agency explained that the name was connected to the German word “Blume,” or flower, and the imagery of a small seed growing into a flower. The group’s official introduction emphasized individual growth and the combination of the members’ different strengths.
The Story of ablume
Before their music debut, the members shared more of their journey through a documentary series titled ** The Story of ablume **. The six-episode series began releasing in March 2025 and gave viewers a closer look at their preparation and transition into the new group.
The project was important because it allowed ablume to establish its own narrative instead of relying only on the members’ previous FIFTY FIFTY history.
Official Debut With “Echo”
ablume officially debuted in May 2025 with “Echo.”
The release included “Echo,” “Never Far Away (Prologue)” and “Echo (Inst.)” and was issued through MASSIVE E&C.
The members described “Echo” as a song about connection, friendship and continuing to move forward. In interviews, Sio explained that its message fit the group’s story and that the trio wanted its first title track to communicate determination and a sense of freedom.
2025 Activities
Following the debut, ablume released additional versions of “Echo” and official performance content.
The group also released “Echoes of Echo” in May 2025, containing alternate, sped-up and slowed-down versions of the song.
One notable official video was a “Cupid (Bossa Ver.)” live performance, which allowed the three members to revisit a song closely associated with their previous career while performing it under their new identity.
2026 and Current Status
In April 2026, an Asia Business Daily report about corporate changes at IOK ENM stated that the music business would be developed around independent label Massive V&C and that ablume was scheduled to release a full-length album targeting the global market within 2026. The article also said CEO Youngseok Park would directly lead the group’s overseas expansion.
However, the group’s official website and discography available at the time of writing still center on Echo and its associated videos. Therefore, the 2026 full album should be described as a reported plan, not as an already released album.
Agency and Management
ablume initially signed with MASSIVE E&C, which was introduced as a new label associated with IOK Company/NS ENM in 2024.
The agency’s role became particularly significant because ablume represented a new beginning for three already-known performers. Their debut preparation included documentary content, interviews, music production and international-facing promotional activities.
In February 2025, MASSIVE E&C confirmed that the members had personally requested to work with producer Ahn Sung Il, also known professionally as SIAHN, on their new music. The announcement generated public discussion because of Ahn’s previous connection to FIFTY FIFTY’s production and the legal controversy surrounding the group’s earlier years. The members and agency publicly addressed what they considered inaccurate reporting around the arrangement.
In 2026, corporate reporting began referring to Massive V&C as the independent label around which the music business would be organized. For readers tracking the group, it is therefore useful to distinguish between the original MASSIVE E&C branding and later corporate reporting about Massive V&C.

Some physical and personality details above come from secondary idol databases rather than an official MASSIVE E&C profile. Because these details can change or conflict between databases, readers should treat them as reference information rather than agency-certified statistics.
Early Life and Education
Saena was born in Busan, South Korea, and developed an interest in dance at a young age. Secondary profiles document her participation in dance academies and school dance activities before she entered the K-pop trainee system.
Her most notable pre-debut television appearance was KBS 2TV’s Dancing High in 2018. She participated as part of Team Hoya, giving her an opportunity to perform on national television before her official idol debut.
She also spent time in dance teams and trained in styles including jazz and street dance. These experiences became an important part of her identity as a performer.
Career Journey
Saena trained for roughly two years before debuting in FIFTY FIFTY. In a pre-debut interview, she said she started her trainee period as a high-school freshman and spent approximately two years preparing. Once the four-member FIFTY FIFTY lineup was confirmed, the members had roughly three months to prepare for their official debut.
She debuted with FIFTY FIFTY on November 18, 2022. During that period, Saena served as the group’s leader.
Her dance background became particularly visible through FIFTY FIFTY’s performance of “Cupid.” KProfiles attributes the song’s viral point choreography to Saena, although this is a secondary-source claim rather than a currently accessible agency biography.
After the legal dispute involving FIFTY FIFTY and ATTRAKT, Saena left the agency and later signed with MASSIVE E&C alongside Sio and Aran in August 2024.
In ablume, Saena remains the leader. During a Genius Korea interview, she explained that she sees herself partly as a bridge between Sio and Aran’s contrasting vocal colors, helping create a balanced group harmony.
Personal Interests
Publicly documented interests associated with Saena include photography, cleaning and going for walks. She has also said that she would consider photography as an alternative career if she were not an idol. Her favorite singer has been identified as Daniel Caesar, and she has cited BLACKPINK as a role model.
Family Background
Specific details about Saena’s parents and broader family life are not comprehensively documented by official sources. Secondary profiles have mentioned siblings and pets, but these are personal details that should not be treated as fully verified without a direct member or agency source.
Parents’ occupations: This information is not publicly available.
Sibling information: Secondary profile sources report an older brother, but a current official source was not located.
Relationship Status
There is no reliable public confirmation of a current romantic relationship involving Saena.

2. Sio Profile
Sio Personal Information
| Field | Details |
|---|---|
| Stage Name | Sio (시오) |
| Full / Birth Name | Jeong Ji-ho (정지호) |
| Korean Name | 정지호 |
| Date of Birth | October 6, 2004 |
| Age | 21 as of September 22, 2026 |
| Zodiac Sign | Libra |
| Chinese Zodiac | Monkey |
| Birthplace | Yeosu, South Korea is the commonly reported location |

| Blood Type | AB |
| MBTI | INTJ in current profile databases |
| Position | Main vocalist / vocalist |
| Representative Emoji | 🐯 in secondary profile databases |
| Training Period | About two years before FIFTY FIFTY debut |
Sio’s core profile information is consistently reported across several secondary K-pop databases, although the precise birth-location data have appeared inconsistently on different fan-maintained pages.
Early Life and Education
Sio is associated with Yeosu, Jeollanam-do, and attended Wonkwang Information Arts High School. Secondary profiles state that she studied music before leaving school to focus on her entertainment career.
Before joining FIFTY FIFTY, Sio was reportedly a P NATION trainee. Her training history gives her an interesting place in the K-pop trainee system because she experienced the process before ultimately joining ATTRAKT.
In a separate interview about the original FIFTY FIFTY lineup, Sio said she had spent around two years as a trainee before debut.
Career Journey
Sio debuted as a member of FIFTY FIFTY on November 18, 2022. She was identified as one of the group’s main vocalists and contributed to the quartet’s vocal-focused sound.
Following the contract dispute with ATTRAKT, she moved forward with Saena and Aran. The three were subsequently signed by MASSIVE E&C in 2024 and introduced as ablume.
In ablume, Sio has publicly introduced herself as the main vocalist. In the group’s Genius Korea interview, she described the importance of expressing emotion through her voice and making her singing feel smooth rather than simply technically precise.
That vocal role is particularly important to the group’s recorded music. The members have described the three voices as having different colors and textures, with Saena acting as a bridge between them.
Music and Personal Interests
Sio’s publicly documented interests include reading, writing and anime. She has also been associated with guitar playing in secondary profiles. She has cited THORNAPPLE as a favorite group and has spoken about wanting to be an author if she were not an idol.
These interests help explain why her public image within ablume frequently emphasizes vocals and a more reflective side of the group’s identity.
Career Goals
In interviews around ablume’s debut, Sio spoke about the difficulty of returning to performance after a long break and described the new beginning as a more grounded musical period. She has also expressed an interest in reaching international audiences through live performances.

Detailed information about Sio’s parents, family occupations and private family life is not publicly documented by the agency.
Parents’ occupations: This information is not publicly available.
Sibling information: This information is not publicly available from reliable primary sources.

Profile databases vary on some physical details, particularly height, and these figures are not currently presented as an official agency profile.
Early Life and Education
Aran was born in Seoul, South Korea, and attended the School of Performing Arts Seoul, according to public profile sources. She studied practical music before leaving school to focus on her professional career.
Her interest in becoming an idol developed at a young age. Secondary profiles have documented that Girls’ Generation played an important role in her early interest in K-pop and performance.
Aran was the last of the four original FIFTY FIFTY trainees to join that debut team, according to an interview with the group. She said she had about two years of trainee experience overall.
Career Journey
Aran debuted with FIFTY FIFTY in November 2022 and quickly became particularly recognizable for her vocal color. The group’s success with “Cupid” gave her significant international exposure while she was still a young performer.
After the contract dispute with ATTRAKT, Aran moved forward with Saena and Sio. The trio signed with MASSIVE E&C in August 2024 and formally became ablume later that year.
In ablume, Aran describes herself as a vocalist. She has also spoken about enjoying singing, rapping and dancing with the other two members, showing that she approaches performance as more than a single-position role.
Aran’s public musical influences include John K, Loco, DEAN and Crush, while Ariana Grande has been identified as a role model.
Personality and Interests
Aran has discussed music as a source of comfort and connection. In an interview around the debut of ablume, she said music had been something she naturally turned toward since childhood and that she wanted her work to communicate sincere emotions.
She has also said that, without an idol career, she might have pursued work as a voice actor. Public profile sources list browsing pictures of cats and food among her hobbies.
Current Artistic Direction
During a Genius Korea interview, Aran said the group’s upcoming material would have a different character from “Echo,” with a bolder and more energetic direction. That statement is relevant when looking at the group’s intended artistic evolution, although a later full album had not yet been released by the date of this article.
Family Background
Aran’s parents’ occupations and detailed private family background are not publicly available from reliable primary sources.
Parents’ occupations: This information is not publicly available.
Sibling information: Secondary profile sources have reported that she has a younger brother, but the agency has not published a comprehensive family biography.

Former Members
Does ablume Have Any Former Members?
No.
Saena, Sio and Aran are the current three members of ablume. There is no verified former-member lineup for ablume itself.
The three had previously been members of FIFTY FIFTY, but their status in that earlier group is separate from ablume’s membership history.
ablume Discography
Because ablume is still a young group, its official discography is currently small.
Single Album
| Release | Date | Tracks |
|---|---|---|
| Echo | May 2025 | “Never Far Away (Prologue),” “Echo,” “Echo (Inst.)” |
The official ablume discography identifies Echo as the group’s debut release, with the label listed as MASSIVE E&C.
Additional Release
| Release | Date | Details |
|---|---|---|
| Echoes of Echo | May 28, 2025 | “Echo (Alt Version),” “Echo (Sped Up Version),” “Echo (Slowed Down Version)” |
Notable ablume Songs
“Echo” is currently the group’s defining original song and debut title track. The group selected it because its themes of love, friendship, unity and perseverance matched their new identity.
“Never Far Away (Prologue)” offers a much softer, piano-centered sound and functions almost as an emotional preface to the group.
Music Style and Influence
ablume’s early musical identity is strongly based on vocal harmony.
The official website describes the trio’s sound using “sweet” and “angelic” harmonies, while the members have spoken about their different vocal textures complementing one another.
“Echo” combines a bright pop approach with layered vocals and an emotional message. The members have described the song as an expression of connection, friendship and continuing to move forward.
The group has also indicated that its sound is not intended to remain fixed. Saena said the trio wants to explore different sounds and continue discovering its musical identity, while Aran teased a stronger and more spirited direction for future music.
That makes ablume’s musical development particularly interesting: their first era established warmth and harmony, while their own interviews suggested that future material could broaden their sonic range.
Awards and Achievements
Major Achievements as ablume
| Achievement | Status |
|---|---|
| Official debut | May 2025 |
| Debut title track | “Echo” |
| Official documentary series | The Story of ablume |
| International promotional interviews | Yes |

| Major music-show win | No verified win located |
| Major award win | No verified win located |
| Full-length album | Planned for 2026; not yet released as of Sept. 22, 2026 |
The trio’s largest pre-ablume achievement came through their work in FIFTY FIFTY. “Cupid” reached No. 17 on Billboard’s Hot 100 and spent an extended period on international charts, giving all three members significant prior recognition.
This distinction matters because achievements from FIFTY FIFTY should not be presented as awards won by ablume.
Tours and Concerts
A major world tour by ablume has not been officially announced.
In a 2025 interview, the members were asked about possible world-tour destinations. Sio mentioned California, Saena named Mexico, and Aran mentioned New York and Paris as places where they would like to perform. These were personal wishes rather than an announced tour schedule.
The group was also listed in connection with the K-Street Festival 2025 in Paris, but an event listing by itself should not be interpreted as proof that every listed artist performed.
Verified major ablume tours: None located.
Official 2026 tour schedule: This information is not publicly available.
Brand Endorsements and Ambassadorships
No major long-term official brand ambassador appointment for ablume was located in the primary or major entertainment sources reviewed for this article.
As a young group with limited public commercial activity documented so far, claims on fan pages or unverified promotional sites should not be treated as formal endorsements.

Net Worth and Revenue Sources
There is no reliable public figure for ablume’s group net worth, and there are no verified individual net-worth figures for Saena, Sio or Aran.
K-pop group income can come from several areas, including:
| Revenue Source | ablume Status |
|---|---|
| Music streaming | Yes |
| Digital music sales | Yes |
| Physical albums | Limited public release history so far |
| Concerts | No large tour publicly confirmed |
| Merchandise | Some group-related merchandise activity exists, but public financial figures are unavailable |
| Endorsements | No major confirmed long-term deal located |
| YouTube / digital content | Official content exists |
| Acting | No verified major acting career for the current group |
| Personal appearances | Limited public record |
Album sales, streaming revenue and other income are divided according to contractual arrangements that are not publicly available. Therefore, it would be misleading to calculate a precise personal income amount from public view counts alone.
