KISU Embarks on a New Chapter as an Independent Solo Artist Following Departure from 24K and Completion of Military Service

The landscape of the South Korean music industry is defined by its rapid transitions, rigorous training systems, and the often-challenging evolution from group member to solo performer. Among those navigating this complex path is Choi Ki-su, known professionally as KISU, who has officially announced his intention to return to the music scene as an independent solo artist. This move follows a significant hiatus necessitated by mandatory military service and a subsequent departure from his original group, 24K. As the K-pop industry continues to expand globally, KISU’s transition serves as a case study in the resilience required of veteran idols seeking to reclaim their creative identities outside the traditional agency framework.

The Foundation: A Decade of Musical Contribution

To understand the significance of KISU’s return, one must examine the foundations of his career within the group 24K. Debuting on September 6, 2012, under Choeun Entertainment, 24K emerged during a transformative era for K-pop. At the time, the "Third Generation" of K-pop was beginning to take shape, characterized by an increasing emphasis on global digital reach and experimental production. KISU served as the main vocalist for the group, a role that demanded not only technical vocal proficiency but also the ability to anchor the group’s diverse discography, which spanned from aggressive EDM-infused tracks to more melodic, R&B-leaning compositions.

During his tenure with 24K, KISU was instrumental in the release of several key projects that defined the group’s signature sound. This included mini-albums such as "Hurry Up," "U R So Cute," and the critically acclaimed "Super Fly." The latter, released in 2015, became a pivotal moment for the group, garnering international attention for its high-energy choreography and trap-heavy production. This global interest allowed KISU and his bandmates to embark on extensive international tours, reaching audiences in Europe, South America, and across Asia—regions where 24K maintained a particularly loyal following, often referred to as "24U."

However, the trajectory of 24K was also marked by frequent lineup changes, a common challenge for mid-tier K-pop groups. Despite these fluctuations, KISU remained a constant presence and a stabilizing force within the group for nearly seven years. His departure in 2019, therefore, marked the end of an era for both the artist and the remaining members, signaling a definitive shift in his professional journey.

The Mandatory Hiatus and the 2019 Transition

In the South Korean entertainment industry, mandatory military service represents a significant hurdle for male idols. Under South Korean law, all able-bodied men are required to serve approximately 18 to 21 months in the armed forces. For K-pop stars, this often means a forced pause at the height of their careers, risking a loss of momentum and public visibility.

KISU began his military enlistment in May 2018. While he was away serving his country, the internal dynamics of 24K and Choeun Entertainment underwent substantial changes. In 2019, while KISU was still fulfilling his duties, it was officially announced that he would be leaving the group. This departure was handled with professional discretion, framed as a natural progression as KISU looked toward his future post-service.

The timing of such departures is critical. By leaving the group during his service, KISU was able to utilize the period of his enlistment to mentally and strategically prepare for a solo career. When he was officially discharged in June 2020, he entered a music industry that had changed significantly since his 2012 debut. The rise of short-form video content, the dominance of streaming platforms, and a heightened demand for artist-driven, authentic storytelling provided a new set of opportunities for an independent artist.

Re-establishing Presence: The Role of Digital Platforms

Since his discharge in mid-2020, KISU has focused on rebuilding his connection with his fanbase through direct digital engagement. Eschewing the immediate pressure of a major label comeback, he turned to YouTube as a primary medium for artistic expression. His channel has served as a digital portfolio, featuring high-quality vocal covers that showcase his range and versatility.

These covers are more than just performances; they are a strategic tool for maintaining "brand" awareness in an industry where out-of-sight often means out-of-mind. By interpreting popular tracks and sharing glimpses of his daily life, KISU has successfully bridged the gap between his identity as a "group idol" and his new persona as an "independent soloist." This period of digital activity has allowed him to gauge current musical trends while refining his own sonic direction, which appears to be leaning toward a more mature and emotionally resonant style compared to the high-tempo dance tracks of his earlier career.

The Independent Path: Challenges and Opportunities

Choosing to return as an independent artist is a bold move in an industry historically dominated by large entertainment conglomerates like SM, YG, JYP, and HYBE. However, the "independent soloist" model is becoming increasingly viable due to several factors:

1. Creative Autonomy: Independent artists have total control over their musical direction, image, and release schedules. For a veteran like KISU, this means the freedom to produce music that reflects his personal experiences rather than following a manufactured group concept.
2. Direct Monetization: Without a major agency taking a substantial percentage of earnings, independent artists can see a higher return on digital sales, streaming, and merchandise, provided they can manage their own overhead costs.
3. Direct Fan Interaction: Social media platforms allow artists to bypass traditional gatekeepers (TV networks and major publications) to reach their audience directly. KISU’s active presence on Twitter and Instagram is a testament to this shift.

Despite these advantages, the challenges remain formidable. Independent artists must self-fund their production, marketing, and distribution. They lack the institutional "push" that helps major label artists secure spots on music shows or high-profile variety programs. For KISU, success will depend on the loyalty of his existing international fanbase and his ability to capture the interest of new listeners through high-quality independent production.

Chronology of Key Milestones

To provide a clear perspective on KISU’s career trajectory, the following timeline outlines his journey from debut to his current solo endeavors:

• September 6, 2012: KISU officially debuts as a member of 24K with the mini-album "Hurry Up."
• 2013 – 2017: Active participation in multiple group comebacks, including "U R So Cute" (2013), "Hey You" (2015), and "Super Fly" (2015). The group gains significant traction in Europe.
• December 2017: KISU releases his first solo album "Sweet Lie" while still a member of 24K, hinting at his potential as a standalone artist.
• May 2018: KISU enlists in the South Korean military for mandatory service.
• 2019: Official announcement regarding KISU’s departure from 24K and Choeun Entertainment.
• June 2020: KISU completes his military service and is honorably discharged.
• Late 2020 – Early 2021: Launch and growth of his YouTube channel, focusing on vocal covers and fan engagement.
• Present: Preparation for a formal return to the music industry as an independent solo artist.

Industry Implications and Future Outlook

KISU’s return as an independent artist reflects a broader trend within the K-pop ecosystem. As "Second" and "Third Generation" idols reach their 30s, many are opting for independence or joining smaller, artist-centric labels rather than renewing contracts with their original agencies. This shift is leading to a more diverse and fragmented market where veteran artists can sustain long-term careers by catering to niche, dedicated fanbases rather than seeking mass-market pop dominance.

Analysts suggest that the success of independent soloists like KISU will likely depend on their ability to leverage "global K-pop" infrastructure. This includes using international distribution aggregators and performing at overseas conventions and festivals that cater specifically to Hallyu fans. Given KISU’s history of touring with 24K, he possesses a foundational understanding of the global market that many new soloists lack.

The upcoming music from KISU is highly anticipated by those who have followed his decade-long career. While specific details regarding the genre and release date of his new project remain under wraps, his recent interviews and social media activity suggest a focus on authenticity and vocal performance. By stepping away from the "idol" machinery and embracing the "artist" identity, KISU is positioning himself not just as a former group member, but as a seasoned musician with a distinct story to tell.

As he prepares for this launch, the industry will be watching to see how he balances the demands of self-management with the creative rigors of music production. If successful, KISU’s independent journey could serve as a blueprint for other veteran idols looking to navigate the transition from group dynamics to solo longevity. For now, the artist remains focused on his craft, expressing gratitude to the fans who have remained by his side through nearly two years of military service and a year of independent preparation. The next chapter for Choi Ki-su is not just a comeback; it is a reinvention.
