ARGON Members Profile 2026: Names, Ages, Positions & Interesting Facts
ARGON arrived in March 2019 as a six-member boy group under MSH Entertainment, carrying a name that doubled as a mission statement: “ART Go On” . The group debuted with the single album Master Key, followed by a second release, Go Forward: Wide Dream, in October of the same year . Then, quietly, the music stopped.
For readers searching for an ARGON members profile in 2026, the story is less about a dramatic rise and more about a short, documented run and what each member did afterward. The lineup never publicly changed: Kain, Haneul, Roel, Yeoun, Gon, and Jaeun remain the six names associated with ARGON . But the group’s official activity effectively ended in late 2020, and no disbandment announcement was ever made .
This profile separates what is verified from what is reported or presumed. Each member receives a dedicated section, but where public information is thin, that is stated plainly rather than filled with speculation.

Who Is ARGON?
ARGON was a six-member South Korean boy group formed by MSH Entertainment. The group debuted on March 11, 2019, with the single album Master Key, and released one further project, the mini album Go Forward: Wide Dream, on October 2, 2019 . The name ARGON is both a reference to the chemical element and an acronym for “Art Go On,” reflecting an intention to move across genres rather than be confined to one sound .
The group’s public activity slowed dramatically after 2019. A crowdfunding campaign for a planned release in 2020 reached its target but the album was never issued, and ARGON’s final official content update arrived on October 1, 2020 . No formal disbandment statement followed. In the years since, the members have moved into dancing, solo music, survival programs, and entrepreneurship, which is where most of the ARGON story now lives.
Group History
Formation and Pre-Debut
ARGON’s pre-debut rollout began in May 2018 when MSH Entertainment opened official social media accounts . Members were introduced one by one between November 19 and November 23, 2018: Kain first, then Haneul, Roel, Yeoun, and finally Gon and Jaeun .
Two members arrived with prior industry experience. Jaeun had debuted in the boy group INX in 2016 under the stage name Win; INX released two digital singles and an album before filing a lawsuit against their agency, winning the case in June 2018 and terminating their contracts . Kain had spent roughly three years as a backing dancer for BTS, including the 2017 Wings Tour, an experience he later cited as the reason he pursued idol work .
Official Debut
Master Key was released on March 11, 2019, with a debut showcase held at Ilji Art Hall in Gangnam the same day . The single album entered the Gaon Album Chart at number 70 . Soompi described the debut music video as having a “fantasy-like concept,” and noted that Kain helped choreograph the title track .
Japanese Promotional Push
From April 28 to late July 2019, ARGON held a long-term Japanese live residency at K-Stage O in Shinjuku, Tokyo, performing 62 small concerts across 31 days . Japanese media outlet Kstyle reported that the run was extended with additional July dates due to demand, and that the final show took place on July 21, closing a three-month promotional period . A second solo Japanese live was announced for September 2019 .
Second Release and Fandom Name
Go Forward: Wide Dream arrived on October 2, 2019, led by the single “Give Me Dat” . The EP entered the Gaon Album Chart at number 54, with reported sales of 483 copies . The fandom name A-RANG was announced alongside this release . The lyrics of “Give Me Dat” were described as expressing the group’s wish to “rise to the top” .
The Quiet End
In May 2020, a Makestar crowdfunding project for ARGON’s next release reached 250 percent of its target, but the planned album was never released and the project was ultimately cancelled . ARGON continued posting content until October 1, 2020, after which official activity ceased . Neither MSH Entertainment nor any member issued a disbandment statement. Jaeun later posted an ARGON photo captioned “2019-2020,” which fans and profile databases have treated as a quiet confirmation that the group’s run had ended .
Agency and Management
ARGON was managed by MSH Entertainment throughout its active period . Kpopping’s company history also lists Oneworld Entertainment as a former affiliated entity between 2018 and 2020, though this is not corroborated by a primary MSH announcement . No public information explains the exact corporate relationship between the two names. MSH Entertainment has not issued a formal statement about ARGON’s status, and the agency’s current artist roster is not publicly detailed in accessible sources.

His training period under MSH is not publicly documented in exact months, though his pre-debut dance career with BTS spanned roughly three years .
Early Life and Education
Kain’s pre-debut life outside of dance training is not extensively documented. Publicly available sources do not specify his childhood, hometown, or school history. What is documented is his martial arts background: he holds a black belt in Kendo and previously taught the discipline . This detail has circulated across profile databases but has not been the subject of a dedicated interview. His education history is not publicly available.
Career Journey
Kain’s career before ARGON is the most substantial in the group. He worked as a backing dancer for BTS, including the 2017 Wings Tour, for approximately three years . At ARGON’s debut showcase, he explained the transition: “I enjoyed standing on stage because of the cheers from the audience. I wanted to know what it would feel like if those cheers were for me, so I decided to debut” . He also spoke about watching BTS rehearse 16 hours a day and cited their work ethic as an influence .
After ARGON’s activity ceased, Kain returned to professional dancing. Since 2021, he has worked as a backup dancer under the name Junho for artists including ENHYPEN, Red Velvet, SF9, and Hpresso .

Haneul Profile
Personal Information
| Category | Details |

| Full Name | Lee Haneul (이하늘) |
| Korean Name | 이하늘 |
| Stage Name | Haneul (하늘) |
| Date of Birth | June 3, 1996 |
| Age (2026) | 29 |
| Zodiac Sign | Gemini |
| Chinese Zodiac | Rat |
| Birthplace | South Korea |
| Nationality | South Korean |
| Height | 176 cm (5’9″) |
| Weight | 58 kg (127 lbs) |
| Blood Type | Not publicly confirmed |
| MBTI | Not publicly confirmed |
Group Role
Haneul’s official position was vocalist and rapper . He was the second member revealed, on November 20, 2018 . Profile sources note that he was originally intended as a vocalist but was added to the rap line because of his ability . No representative emoji was officially assigned. His exact training period is not publicly documented.
Early Life and Education
Haneul’s childhood and education are not publicly detailed. One frequently repeated profile fact states that he can walk on his hands, which suggests an early interest in physical performance, but this has not been framed as formal training . His school history is not publicly available.
Career Journey
Haneul’s pre-debut career is the least documented among the members. He was revealed as part of ARGON’s lineup in November 2018 and debuted with the group in March 2019 . After ARGON’s activity ended, he completed his mandatory military service, with profile databases placing his discharge sometime between May and July 2022 .
Kpopping’s group profile states that a “Haneul (born Lee Cheol Hyeok)” signed with YM Entertainment in 2024 and participated in survival programs . This presents a name discrepancy: the same source elsewhere refers to Haneul’s birth name as Lee Haneul, while the post-disbandment entry uses “Lee Cheol Hyeok.” No primary source confirms whether this is the same person, a legal name change, or a database error. This connection is reported but not confirmed, and readers should treat it as unverified.
No solo music, acting, or hosting credits have been publicly documented for Haneul under the name Lee Haneul.

Group Role
Roel was ARGON’s lead vocalist . He was the third member revealed, on November 21, 2018 . No representative emoji was officially designated, and his training period is not publicly documented.
Early Life and Education
Roel’s pre-debut life is lightly documented. He was active in his school’s broadcasting club from elementary through high school and served as an announcer during high school . This is one of the few concrete childhood details available for any ARGON member. His hometown and university history, if any, are not publicly available.
Career Journey
Roel’s career consists of ARGON’s 2019 activities and little else that is publicly verified. He participated in the group’s debut and second release but has no documented solo music, acting, variety, or hosting work. Kpopping’s group profile states that Roel and Yeoun are “believed to have stepped away from the entertainment industry” . This is a reasonable inference from the absence of public activity, but it is not a confirmed statement from either member. No official post-ARGON career path has been announced.

Japanese Releases
No standalone Japanese singles or albums are publicly documented. ARGON’s Japanese activity consisted of live performances and promotional events, including the 2019 K-Stage O residency and a second solo live announced for September 2019 .
Notable Songs
“Master Key” and “Give Me Dat” are the group’s two known title tracks. “Give Me Dat” was described in Melon’s album notes as a song expressing each member’s desire to grow and rise toward the top .
Music Style and Influence
ARGON’s musical identity was built around a dual concept. The name referenced the chemical element argon, with the group explaining they were “not limited to a single color” and could “absorb multiple genres” . The “Art Go On” acronym reinforced this as a statement of artistic persistence rather than a fixed sonic brand .
Their two releases sit within the late-2010s boy-group landscape: polished dance-pop with rap breaks, choreography-heavy performances, and a fantasy-tinged visual concept on debut . Kain’s background as a BTS dancer shaped the group’s performance identity, and his choreography credit on “Master Key” gave the debut a personal stamp . Beyond these details, no member has publicly discussed specific musical influences or the group’s intended artistic evolution in depth.
Awards and Achievements
ARGON did not win any major domestic music awards or music show trophies during their active period. No verified award nominations or wins are publicly documented.

Conclusion
The ARGON members profile is not a story of chart dominance or arena tours. It is a record of a six-member group that debuted with a clear concept, released two projects, mounted an ambitious Japanese live schedule, and then quietly stopped. Kain went back to professional dancing and built a second career behind the stage. Gon pushed through survival shows and released solo music. Jaeun built his own agency. Haneul, Roel, and Yeoun have kept a much lower public profile, with limited verified information about their current activities.
What remains verifiable is the lineup, the music, the Japanese residency, and the members’ documented post-ARGON paths. Everything else-unconfirmed disbandment theories, net worth estimates, and speculation about the quieter members-should be treated with caution. ARGON’s “Art Go On” may have been a slogan, but for several of its members, the art did continue, just not in the form the group’s debut promised.
