This profile covers one person across several names and roles. Ze:U, Yoon Jongwoo, and ONE PACT’s Jongwoo are the same person. His former-group history, current membership, production work, and official solo track all belong on this canonical page. RAPH4EL is TAG’s solo name, not Jongwoo’s.
Before ONE PACT
Jongwoo first debuted in 2022 as Ze:U, a member of BLACK LEVEL. The group operated on a small scale and did not give him the reach that later survival-show audiences would provide, but it gave him practical experience with rehearsals, formations, music programs, and the pressure of trying to establish a new idol team.
BLACK LEVEL’s short career is not simply a failed preface. It explains why Jongwoo entered his next chapter with a working understanding of group logistics. He had already learned that good individual dancing does not automatically create a readable team performance and that an idol career can end even after the debut milestone has been reached.
After BLACK LEVEL, he competed on Mnet’s Boys Planet in 2023. His early screen time and initial recognition were limited compared with several trainees carrying larger fandoms or well-known agencies. Over the season, however, he became associated with leadership, dance control, and an underdog rise built through actual stages rather than a single viral introduction.
Boys Planet and the Rank 18 Finish
Jongwoo’s Boys Planet story is often summarized as a climb to eighteenth place, but the performance details explain why that rank mattered. He learned how to make compact movement register on broadcast cameras, how to guide teammates with different experience levels, and how to present a stronger identity without abandoning the role a team needed from him.
The program placed him near several artists who would later shape his next group. Jay Chang, Seongmin, and Yedam also competed on Boys Planet; TAG came from a separate survival and group history. Their shared experience of public evaluation meant ONE PACT was built from members who understood both debut pressure and what it feels like to miss a survival-show lineup.
ARMADA ENT announced Jongwoo as the first member and leader of ONE PACT in September 2023. The choice positioned him as the organizing center before the full lineup was revealed. It also turned the relationships formed around Boys Planet into a permanent group rather than a temporary reunion project.
ONE PACT: Debut and Group Identity
ONE PACT debuted on November 30, 2023 with the mini album Moment. The name combines “one” and “impact,” expressing the goal that the members would create a large impact together. The lineup consists of Jongwoo, Jay Chang, Seongmin, TAG, and Yedam.
The team differs from many rookie groups because nearly every member arrived with a substantial public history. Jongwoo brought BLACK LEVEL and Boys Planet; Jay had a solo career and competition appearances; Seongmin had promoted in TO1; TAG had been part of Ciipher and worked as a producer; Yedam had multiple survival-show experiences. Jongwoo’s leadership therefore does not depend on pretending the other members are inexperienced. His work is to coordinate five artists with their own established instincts.
ONE PACT followed its debut with releases including [fallIn’], PINK CRUSH, and ONE FACT. TAG became central to the group’s songwriting and production, while Jongwoo developed the visual side through self-made video work. The division of labor gives the group an identifiable internal-production story instead of using “self-produced” as a vague promotional label.
In 2025, the group expanded through European and North American touring and released ONE FACT. Its structure gave each member an individual song before returning to the full group. Jongwoo’s solo track “PASSOUT” made his own musical color visible inside a ONE PACT release before he launched a separate formal solo identity.
Dance, Leadership, and Video Direction
Jongwoo is a self-taught dancer and choreographer whose performance style emphasizes clear transitions and controlled weight. He does not need to make every count enormous. His strongest stages show an understanding of how the eye travels across a formation and when another member needs space to become the focal point.
That spatial awareness extends to directing and editing. ONE PACT’s official Japanese profile credits Jongwoo with music-video production work for “RUSH IN 2 U,” “PERIOD,” “Reach You,” and “Confession,” including direction, filming, or editing. These credits are important because they show creative work attached to specific releases, not merely a member expressing interest in cameras.
His leadership is similarly practical. In interviews, ONE PACT has described the ease of working with members who already understand professional expectations. Jongwoo’s job is less about issuing dramatic commands and more about keeping preparation coherent, reading what a stage needs, and helping independent personalities function as one unit.
Solo Music: PASSOUT
Jongwoo’s verified individual release is “PASSOUT” featuring TAG, issued as a Jong Woo solo version on ONE PACT’s 2025 digital EP ONE PACK. Jongwoo wrote the lyrics, performs the lead vocal, and appears in an official special video published by ONE PACT.
The release is attached to this canonical profile because it is explicitly credited as a Jong Woo solo. It does not make RAPH4EL one of Jongwoo’s aliases. RAPH4EL is the solo identity used by fellow ONE PACT member TAG.
ONE PACT in 2026
ONE PACT released its first EP 1’ONLY on February 26, 2026. The five-track release was led by “Sane” and arrived about seven months after ONE FACT. It presented the group’s established duality between intense performance and the less controlled feelings behind the idol image.
Jongwoo’s 2026 schedule centers on ONE PACT activity and his continuing creative work. His verified individual catalog remains anchored by the 2025 solo version of “PASSOUT.”
In July 2026, ONE PACT returned with the digital single “TUNED IN,” a release shaped by a vintage 1990s pop mood. TAG again handled the production, while the full lineup continued the group’s collaborative identity. As of August 12, 2026, Jongwoo remains ONE PACT’s current leader and an active solo artist.
