Jaewon

Jaewon is part of SM Entertainment's public trainee team SMTR25, a pre-debut unit pushed into open view through Reply High School and the April 2026 single We Go Up. The rollout matters because SM rarely gives trainees this much audience-facing runway before a final debut lineup is locked. Jaewon entered that system as one of the youngest Korean faces in the project, with the show framing him inside the "10s Class" and turning his trainee period into weekly content rather than private prep.

That visibility has already made him more than a background name in the pipeline. SM Entertainment used SMTR25 across SMTOWN LIVE 2025, Mnet's Reply High School, and the early-performance cycle around We Go Up to test audience response in real time. For Jaewon, that means his profile is being built before debut through official stages, reality storytelling, and the kind of global-city SM appearances that signal long-term plans instead of one-off trainee content.

HITKULTR is tracking Jaewon at the exact point where pre-debut curiosity starts turning into measurable fandom. He is still in trainee status, but the public record is already clear: he was born on February 16, 2008, he represents Korea inside a multinational SMTR25 class, and he is part of a project jointly amplified by Mnet and SM as the company prepares its next boy-group era.

Who is Jaewon in SMTR25?
Jaewon is a South Korean trainee in SM Entertainment's public pre-debut team SMTR25. He became part of the project's audience-facing rollout through Mnet's 2026 reality series Reply High School, where SM introduced trainees by era-based classes instead of waiting for a final boy-group debut announcement.
How old is Jaewon from SMTR25?
Jaewon was born on February 16, 2008. That places him among the younger Korean trainees in the SMTR25 public lineup introduced through Reply High School in September 2025, then carried into the group's 2026 pre-debut music and performance schedule.
Has Jaewon debuted yet?
No. Jaewon is still in the trainee phase. He has appeared in official SMTR25 content, the Mnet series Reply High School, and the 2026 single We Go Up, but SM Entertainment has not confirmed the final debut lineup or formal launch details for its next boy group.
What is Jaewon known for right now?
Right now Jaewon is known for SMTR25's pre-debut push across Reply High School, We Go Up, and the wider SM trainee showcase cycle. Those projects gave him early visibility before debut, which is rare in SM's system and a strong signal that the company is actively measuring audience response.
Did Jaewon perform at SMTOWN LIVE 2025?
Yes. SMTR25 was introduced publicly through the SMTOWN LIVE 2025 concert series tied to SM Entertainment's 30th anniversary year, and Jaewon was part of that trainee-team visibility wave before the project expanded into Reply High School and the We Go Up release cycle.
