Who Is IDID?
IDID (pronounced “eye-did”) is a seven-member South Korean boy group formed by Starship Entertainment through the company’s internal survival show Debut’s Plan. The group name is an abbreviation of the phrase “I did it,” carrying the empowering message: “I Did It. Finally I Made It!”. As member Jeong Semin explained, the name extends to include their fans: “With our fans, our team name expands to ‘We did it,’ expressing the accomplishments IDID and our fans will achieve together”.
IDID is Starship Entertainment’s first boy group in approximately five years, following the debut of Cravity. The agency, home to global K-pop acts like MONSTA X, IVE, and KiiiKiii, launched IDID with the vision of creating a “high-end fresh idol” group that combines refined musicality with youthful, unpolished energy.
The group’s musical identity revolves around what they describe as “#ClassicHip”—a signature sound that maintains the sophisticated, weighty essence of hip-hop while incorporating high-teen lyricism and healthy freedom. This unique blend is evident across their releases, from the bold declaration of “STEP IT UP” to the old-school hip-hop groove of “FLY!”.
What sets IDID apart is their authenticity. Rather than presenting a polished, manufactured image, the members embrace their imperfections and individuality. As they stated during their debut promotions, they refuse to conform to expectations, choosing instead to “move forward to our own rhythm”. This philosophy resonates deeply with their growing fanbase, WITHID—a name that symbolizes the unique bond between the group and their supporters, who walk alongside IDID on their journey.
Group History
Formation and Pre-Debut
The story of IDID begins with Debut’s Plan, Starship Entertainment’s internal survival competition that aired from March 14 to May 4, 2025. The show featured 33 Starship trainees competing for the opportunity to debut in the agency’s newest boy group, marking the first such project since Cravity’s debut five years prior.
The competition was structured around various challenges testing the trainees’ vocals, dance, rap, and overall stage presence. Originally, only the top seven trainees were supposed to make the final lineup. However, in a surprising twist during the live finale on May 4, 2025, an eighth member was added to the group. The final lineup was announced with the following rankings: 1st place Kim Minjae, 2nd place Jang Yonghoon, 3rd place Baek Junhyuk, 4th place Park Wonbin, 5th place Chu Yoochan, 6th place Jeong Semin, and 7th place Park Seonghyeon, with Park Junhwan added as the eighth member.
However, the lineup faced an immediate challenge. On June 2, 2025, Starship Entertainment announced that Park Junhwan would be leaving the group due to “controversial social media posts alleged to be written by Park” that surfaced after the finale. The agency cited the mental stress caused by unfounded rumors as the reason for his departure. This reduced IDID to its current seven-member configuration.
Official Debut
Following Park Junhwan’s departure, IDID regrouped and prepared for their official launch. On July 24, 2025, just 81 days after their formation, they released their pre-debut single “STEP IT UP”. The track showcased the group’s fearless attitude and free-spirited energy, featuring bright yet weighty rap verses that established their “#ClassicHip” signature sound.
On September 15, 2025, IDID made their official debut with their first mini-album I did it.. The eight-track project included the pre-debut single “STEP IT UP” alongside new tracks such as “Chan-Ran” (the title track), “Slow Tide,” “ImPerfect,” “So G.oo.D,” “Sticky Bomb,” “Taking Off – Through Your Dreams,” and “Blooming Crown”. The group held a media showcase at 2 PM and a fan showcase at 8 PM on their debut day at YES24 LIVE HALL in Seoul’s Gwangjin District.
The title track “Chan-Ran” (제멋대로 찬란하게) features an upbeat rhythm that highlights the rookie group’s vibrant, free-spirited energy. The debut album’s concept centered on rejecting conformity and embracing individuality—a theme that would become IDID’s defining characteristic.
Breakthrough Success
IDID’s momentum continued with their first digital single “PUSH BACK,” released on November 20, 2025. The hip-hop dance track symbolized the group’s musical evolution and their determination to forge their own path without fear. Alongside the title track, the single included “Heaven Smiles,” another hip-hop-based track that further showcased the group’s versatility.
During this comeback period, IDID officially announced their fandom name: WITHID (pronounced “with-id”). The name combines “with” and “IDID,” representing “a companion who walks together on IDID’s path, with IDID, and by IDID’s side”. The announcement came during a showcase that also featured performances and behind-the-scenes stories.
Major Career Milestones
2026 proved to be a landmark year for IDID. On May 27, they released their second single album FLY!, featuring the title track “FLY!” and the B-side “Attent!on”. The title track, built on an old-school hip-hop boom-bap groove, features heavy rhythm, cowbell sounds, and a lively chant chorus that captures the group’s most authentic and vibrant moment to date. Member Jang Yonghoon described it as “IDID at our most IDID”.
The group promoted “FLY!” for several weeks on major music shows including Mnet’s M Countdown, KBS 2TV’s Music Bank, MBC’s Show! Music Core, and SBS’s Inkigayo. Due to overwhelming fan demand, they extended their promotions to include the B-side “Attent!on,” which had been pre-released at their first fan concert. The group successfully completed six weeks of music show activities.
The pinnacle of their rookie year came on June 20, 2026, when IDID won the Rookie Award at the 35th Seoul Music Awards, held at Inspire Arena in Incheon. This recognition from one of Korea’s most prestigious music award ceremonies solidified IDID’s position as a leading rookie group.
Recent Activities
Following their Seoul Music Awards win, IDID continued to engage with fans through various activities. On July 18, 2026, they held a guerrilla concert titled “Attent!on Area” at Seoul’s Cheonggye Plaza, performing for fans and市民 alike. The event showcased the group’s ability to connect with audiences in intimate, unexpected settings.
The group has also been active in creating self-produced content. Their official YouTube channel features “NALDID” (날딧), a variety series that offers fans an unfiltered look at the members’ daily lives and behind-the-scenes moments. This commitment to fan communication has helped build a strong, loyal following.
Agency and Management
IDID is managed by Starship Entertainment, one of South Korea’s most prominent entertainment agencies. Founded in 2008, Starship has built an impressive roster of artists including MONSTA X, IVE, Cravity, KiiiKiii, and soloists like Jeong Sewoon and K.Will.
Starship is known for its strategic approach to artist development, carefully crafting distinctive identities for each of its groups. The agency’s decision to launch IDID five years after Cravity’s debut reflects its commitment to quality over quantity, ensuring each group receives the attention and resources needed for success.
The agency’s survival show Debut’s Plan was a significant investment, marking Starship’s first internal audition program for a boy group. The show demonstrated the company’s confidence in IDID’s potential, as they were willing to expose the trainees’ journeys to public scrutiny before debut.
While specific contract details are not publicly available, IDID members have discussed their training periods ranging from 10 months to over 4 years, indicating that Starship maintains a rigorous but supportive trainee system.

However, on June 2, 2025, Starship Entertainment announced that Junhwan would be leaving the group due to “controversial social media posts alleged to be written by Park” that surfaced after the finale. The agency cited the mental stress caused by unfounded rumors as the reason for his departure.
Following his departure, IDID was reconfigured as a seven-member group, and no replacement member was added. Park Junhwan’s current activities are not publicly known.

Notable Songs
Music Style and Influence
Musical Identity
IDID’s musical identity is built around what they describe as “#ClassicHip”—a signature sound that combines the sophisticated, weighty essence of hip-hop with high-teen lyricism and healthy freedom. This unique blend is evident across their discography, from their pre-debut single to their most recent releases.
The group’s debut EP I did it. established their musical direction with a mix of upbeat dance tracks and more emotional songs. The title track “Chan-Ran” features an upbeat rhythm that highlights the group’s vibrant, free-spirited energy. Tracks like “ImPerfect” embrace imperfection and draw out a sense of pride, while “Slow Tide” delicately maps the waves of emotion.
Concepts
IDID’s concept rejects conformity and societal expectations. From their debut, they have emphasized the importance of being true to oneself and “moving forward to our own rhythm”. This philosophy is reflected in their music, performances, and visual concepts.
The group’s 2026 comeback FLY! represents an evolution of this concept. Rather than trying to prove something with tension and intensity, the album finds the group’s natural confidence. The playful energy and positive vibe of the title track, with its old-school hip-hop boom-bap groove, showcases IDID at their most authentic.
Artistic Evolution
In just over a year since their debut, IDID has shown significant artistic growth. Their journey from the bold declaration of “STEP IT UP” to the confident, natural energy of “FLY!” demonstrates their evolving artistry. As member Jang Yonghoon noted, “FLY! is IDID at our most IDID”.
The group has also shown versatility in their B-sides. “Attent!on,” promoted alongside “FLY!,” features a sweet melody that showcases IDID’s natural charm, contrasting with the intense confidence of the title track.
Influences
While IDID has not explicitly named specific musical influences, their sound draws from old-school hip-hop, contemporary K-pop, and high-teen aesthetics. The group has cited the desire to create music that resonates with their generation—youthful, authentic, and unafraid to break boundaries.
