Woolin

Woolin is one of the trainees getting real market exposure through SMTR25, SM Entertainment's public pre-debut team. That matters because most SM trainees stay invisible until a lineup is locked. Woolin is already being introduced through weekly content, fan-facing clips, and the school-format storytelling of Mnet's Reply High School.

The current profile is less about a completed idol résumé and more about momentum. Woolin is part of the 15-member cast attached to the April 2026 OST single We Go Up and the Reply High School fan meeting cycle, which means the trainee phase is already being tested in public through music, camera time, and audience response.

That makes Woolin part of a rare SM experiment. Instead of introducing members only after debut, the company is letting fans track the early development of performers inside the wider SM Entertainment system. For now, the key story is visibility, consistency, and whether this pre-debut runway turns into a final rookie-group slot.

What show is Woolin on?
Woolin appears on Reply High School, Mnet's 2026 trainee reality project centered on SMTR25. The show gives each trainee a public runway through missions, variety segments, and school-themed storytelling before SM finalizes its long-term debut plan.
Has Woolin released music yet?
Woolin is attached to We Go Up, the April 2026 OST single released under the SMTR25 banner for Reply High School. While he has not debuted as a standalone idol yet, the project has already moved beyond teaser content and into an official music release cycle.
Will Woolin officially debut with SM Entertainment?
That has not been confirmed yet. SM Entertainment is using SMTR25 as a public trainee platform, so visibility does not automatically guarantee a final debut slot. Still, trainees like Woolin are already being tested in public through content, performance exposure, and fan response.
