BTOB Members Profile 2026: Bio, Names, Ages & Roles
BTOB is a South Korean boy group that debuted on March 21, 2012, with the digital single “Insane” (비밀). The group debuted as seven members, but following Jung Ilhoon’s departure in 2020, BTOB continued with six members: Seo Eunkwang, Lee Minhyuk, Lee Changsub, Lim Hyunsik, Peniel and Yook Sungjae.
For readers searching for a BTOB members profile in 2026, one detail is especially important: the six members do not all belong to the same management company anymore. Eunkwang, Minhyuk, Hyunsik and Peniel are managed through BTOB Company, while Changsub and Sungjae have separate agencies for their individual careers. Yet BTOB itself remains active as a six-member group; all six reunited for the digital single “우리 다시 (We Together)” on March 21, 2026.
That agency arrangement is the most important piece of context for understanding BTOB today. The group has effectively separated individual management from group identity, allowing the members to pursue solo music, acting, musicals and other work while still returning together for BTOB projects. BTOB Company’s own materials explicitly state that the four members under its label continue BTOB activities under the group name.

Who Is BTOB?
BTOB, short for “Born To Beat,” was formed by Cube Entertainment and officially debuted on March 21, 2012. The group’s Japanese official profile describes the name as referring to its aim of bringing new music and stages to audiences.
The group initially built its identity around energetic performances before becoming especially associated with strong vocals and emotional songs. “Missing You,” “Only One for Me” and “Beautiful Pain” became central examples of the mature sound that later defined much of BTOB’s public image. Korea JoongAng Daily similarly highlights those songs when describing the group’s career.
BTOB’s career is also notable for its longevity. Rather than ending group activity when the members left Cube Entertainment, the six continued using the BTOB name after negotiating the trademark arrangement that enabled ongoing group promotions. BTOB Company’s November 2024 notice said the company had acquired management of the group’s trademark rights and that group activities would continue under the BTOB name.
How Many Members Does BTOB Have in 2026?
BTOB has six current members in 2026: Eunkwang, Minhyuk, Changsub, Hyunsik, Peniel and Sungjae.
This can be confusing because BTOB Company officially lists only Eunkwang, Minhyuk, Hyunsik and Peniel as its artists. Changsub is represented by Fantagio and Sungjae by IWill Media for their individual activities. However, BTOB’s March 2026 full-group release included all six members, confirming that the group continues as a six-member act.
The distinction between “members signed to BTOB Company” and “members of BTOB” is therefore important. They are not the same list.

He’s set to star in the SBS drama Nine to Six, playing the lead role of Han Seon-woo in a workplace romance scheduled for the second half of 2026.
BTOB in 2026: A Year of Reunion and Growth
2026 marks a monumental year for BTOB. After two years and ten months, the group made a full-group comeback on March 21, 2026- their 14th debut anniversary.
The digital single was announced through BTOB Company’s official social media on March 12, with a teaser poster featuring a clock set to 3:21- a symbolic reference to their March 21 debut date.
The comeback was particularly meaningful because it followed a period of transition. During the hiatus, members signed with different agencies:
- Eunkwang, Minhyuk, Hyunsik, and Peniel established BTOB Company in February 2024
- Changsub signed with Fantagio
- Sungjae joined IWill Media
Despite being under different management, the six members reunited to celebrate their 14th anniversary and deliver a gift to fans who had waited patiently.
BTOB Agency in 2026
BTOB’s management structure is unusual but clear.
In November 2023, all six members finished their contractual relationship with Cube Entertainment after 11 years. Cube’s official statement listed all six members and confirmed that the contracts would not be renewed.
The members then split into different management arrangements. Eunkwang, Minhyuk, Hyunsik and Peniel joined the newly established BTOB Company, while Changsub signed with Fantagio and Sungjae signed with IWill Media.
That did not mean BTOB dissolved. In fact, the arrangement was tested and reaffirmed in 2026 when all six members returned with “우리 다시 (We Together)” for the group’s 14th anniversary. Korea JoongAng Daily described it as the group’s first full-member release in about two years and 10 months.
BTOB Debut and Early Career
BTOB debuted on March 21, 2012, with the digital single “Insane.” The Japanese official site records that date and identifies the release as the group’s debut single.
Their first mini album, Born TO Beat, followed on April 3, 2012. The group’s early catalog moved through releases including Press Play, Thriller, Beep Beep and Move before its musical direction became increasingly associated with ballad and vocal-driven material.
A major turning point came in 2015 with “It’s Okay.” Yonhap reported in 2016 that BTOB’s later ballad run had already produced multiple music-show victories, with “Remember That” becoming another winner on Show Champion.
Why “Missing You” Became a Defining BTOB Song
“Missing You” is one of the clearest markers of BTOB’s mature musical identity.
Released in 2017, the song became a substantial music-show success. Soompi documented BTOB’s wins across several programs, including the group’s seventh win on Inkigayo in November 2017 and the group’s sixth win on M Countdown earlier that month.
What made that period important was not simply the number of trophies. “Missing You” helped reinforce BTOB’s shift from an early dance-pop identity toward songs in which vocal arrangement, melody and emotional delivery were central to the group’s appeal. That evolution is one reason BTOB’s catalog is still frequently introduced through songs such as “Missing You,” “Only One for Me” and “Beautiful Pain.”
BTOB’s Major Releases
BTOB’s discography includes the 2022 full album Be Together, followed by the 2023 12th mini album Wind and Wish. The Japanese official site confirms the dates for both releases.
Wind and Wish was particularly important in hindsight because it was the final Korean mini album released before the members’ post-Cube management split. In March 2026, Korea JoongAng Daily identified it as the group’s last full-group album before the six-member return.
BTOB then returned on March 21, 2026, with “우리 다시 (We Together)”. The song was released on the group’s 14th debut anniversary, and Hyunsik participated in writing and composing it.
BTOB’s 2026 Full-Group Return
The March 2026 release is probably the single most useful fact for anyone researching BTOB’s current status.
The six members had spent the post-Cube period concentrating heavily on solo careers, acting, musicals and other activities. BTOB Company’s official teaser campaign then confirmed a full-group digital single for March 21, 2026, and the release included Eunkwang, Minhyuk, Changsub, Hyunsik, Peniel and Sungjae.
“우리 다시” was not just another catalog addition. Its release date deliberately matched the group’s debut anniversary, turning the reunion into a statement about continuity. The song’s lyrics and warm guitar-centered arrangement were also presented as a reflection on the time the members had spent apart and the idea of moving forward together.
For readers, this makes BTOB’s 2026 story less about an agency breakup and more about a multi-agency group model that still permits full-team music releases.
BTOB’s 2026 Activities Beyond Group Music
BTOB’s current career is not defined only by group comebacks.
BTOB Company’s 2026 activity archive includes Eunkwang’s OUR YOUTH, Minhyuk’s TEMPERATURE, Peniel’s “IDKI” and numerous live and promotional projects. The same archive also documents BTOB content and performances during 2026.
Changsub has continued his musical-theatre career under Fantagio, while Sungjae continues his separate entertainment career under IWill Media. This division explains why BTOB may appear across several agencies and platforms while still functioning as one group.
BTOB Awards and Career Achievements
BTOB has accumulated recognized awards during its career, particularly as its vocal-driven era became established.
The 30th Golden Disc Awards named BTOB the Best Vocal Group in 2016. The 32nd Golden Disc Awards later recognized BTOB as Best Male Group in the digital music category in 2018.
The group’s music-show achievements are another significant part of its history. “Missing You,” for example, won repeatedly across Korean music programs in 2017, including Show Champion, M Countdown and Inkigayo.
These achievements matter because they show how BTOB’s reputation developed: not through a single breakthrough moment, but through a long transition toward vocal-led songs that became commercially and critically durable.
BTOB Fandom: MELODY
BTOB’s official fandom is known as MELODY.
The name is documented in BTOB’s official fan-community materials, including the group’s former Weverse community, which described the platform as the official global fan community for MELODY.
The former Weverse membership service was later terminated at the end of 2024 after the group’s management structure changed. That termination concerned the platform and membership service, not the existence of BTOB or its fandom name.
Former BTOB Member: Ilhoon
Jung Ilhoon is a former BTOB member and should not be included among the current six.
Cube Entertainment announced his departure from BTOB on December 31, 2020, and said the group would continue as a six-member act. Yonhap independently reported the departure that same day.
For current-profile searches, the simplest distinction is therefore:
Original lineup: seven members
Current lineup in 2026: six members
Former member: Jung Ilhoon
BTOB Members Timeline
BTOB’s career can be understood through a few major turning points: the 2012 debut, the 2015 shift toward stronger ballad material, the success of “Missing You” in 2017, the departure of Ilhoon in 2020, the end of the Cube era in 2023, and the six-member reunion in 2026.
The 2026 release is especially significant because it shows that separate agency contracts do not necessarily end a group’s ability to operate as a group. BTOB’s case provides a useful example of how a long-running K-pop act can restructure management without abandoning the group identity.
BTOB Quick Summary for New Fans
BTOB is best approached through its vocal catalog rather than through a single concept era.
New listeners will generally encounter the group through songs such as “Missing You,” “Only One for Me,” “Beautiful Pain,” “The Song” and “Wind and Wish.” The group’s later music demonstrates why its reputation became closely tied to vocals, while individual members add songwriting, acting, musicals, rap and solo performance to the overall picture.
In 2026, the key thing to remember is that BTOB remains a six-member group even though its members are managed across different companies. The March 21 release of “우리 다시” is the clearest recent proof of that continuing group identity.

Editorial note
For a 2026 BTOB members profile, the most important correction to older profile pages is the distinction between group membership and agency membership. Older pages often list BTOB Company as though it represents all six members, while BTOB Company’s own website represents only Eunkwang, Minhyuk, Hyunsik and Peniel. The six-member “우리 다시” release in March 2026 makes clear that BTOB itself remains a six-member group.
