Kim Jun Seo, known professionally as Junseo, is a South Korean singer, rapper, dancer, and actor. Born November 20, 2001 in Ulsan, he rose to prominence as a member of the Sino-Korean project boy group Alpha Drive One, formed through the survival show Boys 2 Planet. Within the group, he serves as a vocalist and dancer, building a dedicated international fanbase since the group's debut in 2023. As of 2026, he continues to promote with Alpha Drive One, releasing music, performing live, and expanding into acting with minor roles and web drama appearances.

Junseo grew up in Ulsan, a major industrial port city in southeastern South Korea. From a young age, he was drawn to music and performance, though specific details about his childhood and family remain private. He decided to pursue a career in entertainment by auditioning for a major company, eventually becoming a trainee. His big break came when he competed on the survival show Boys 2 Planet in 2023, where his vocals and dance skills caught the attention of both judges and viewers. He secured a spot in the final lineup, leading directly to his debut with Alpha Drive One.[edit]

Junseo's breakthrough came in 2023 when he debuted as a member of Alpha Drive One immediately after Boys 2 Planet concluded. The group's debut single and EP drew strong support from the show's global fanbase, giving him an instant platform. Since then, he has participated in all group activities: music releases, variety shows, fan meetings, and concert tours. While his primary focus remains group promotions, he has also begun exploring acting, taking on minor roles in web dramas and making guest appearances. As of 2026, he continues to build his career within Alpha Drive One, with no solo music releases yet documented.[edit]

As a member of a relatively new group, Junseo's public image is still being shaped. He is known for his energetic performances and warm interactions with fans. His social media presence is professional and fan-oriented, posting behind-the-scenes content and group updates. The Alpha Drive One fandom is global, though a specific fandom name has not been officially announced. Media portrayals highlight his vocal and dance abilities, and he is seen as a rising talent in the K-pop scene.[edit]

Kim Jun Seo stands apart in the current K-pop landscape not for a singular viral explosion, but for the steady, electric momentum of his rise alongside Alpha Drive One. While many rookie acts chase immediate global saturation, his fanbase has built a reputation for disciplined support that bridges the gap between domestic fervor and international reach. The group's debut marked a pivotal shift, yet the audience remains distinctively tight-knit, prioritizing live performance energy over fleeting social media trends. As the collective identity of Alpha Drive One solidifies, the fandom itself remains an evolving entity without a formalized moniker documented in official records. This lack of a specific name does not diminish their impact; rather, it reflects a raw, organic connection where fans identify primarily through the group's shared trajectory rather than a branded label. Despite the absence of a confirmed title, the community actively drives chart movements and engages in coordinated promotional efforts that mirror the strategies of established veteran groups. Their dedication is evident in how they sustain attention across music releases and variety appearances, treating every comeback as a milestone event. iFANN tracks these dynamics through global consumption signals and media coverage to assess standing. Currently, Kim Jun Seo holds no evaluated ranking within the iFANN fame database as data collection for this specific persona phase is not yet complete. Consequently, no ordinal position or comparative scope can be assigned at this time. The absence of a rank reflects the transitional nature of his recent project rather than a lack of visibility.[edit]
