Who Is 'Pink Hair Boy'? Pre-Debut Photos, More Details About the Viral SMTR25 Trainee Revealed

During the electrifying SMTOWN Live 2025 on January 11 and 12, SM Entertainment teased its much-anticipated pre-debut boy group, SMTR25.

Though the 25 members are yet to be formally introduced, a few are already capturing hearts due to their viral fancams that showcase their stunning visuals and skills.

One trainee, in particular, stood out for his head-turning looks in striking pink hair, quickly earning him the nickname "pink hair boy" as fans continued to speculate about his identity.

As his photos and videos swept across social media, veteran Pink Bloods (SM's fans) and EXO-Ls (EXO's fandom) couldn't help but admire his top-notch looks, fondly recalling Xiumin's iconic pink hair from his debut days.

Following the two-day concert, the trainee's clips dominated online portals and community forums, prompting internet sleuths to dig deeper into his identity. Fans tracking SMTR2025 revealed that the "pink hair boy's" name is Oh Hyunjun or Hyeonjun, born in 2006.

Diligent fans on X, according to their collective research, said that Hyunjun hails from Ulsan and was scouted by SM during his early middle school years.

A detective-like post author (OP) added that, while he wasn't originally good at dancing when he joined the label, Hyunjun is passionate about training.

After his supposed profile leaked online, K-Netz—who had been familiar with him even before his trainee days—flooded social media with never-before-seen snaps of the rising star.

Before becoming a trainee, Hyunjun sported black hair and was an internet influencer and TikToker, which left a digital footprint that fans can access.

His old account also hints that his romanized name is Hyeonjun and not Hyunjun, as per his alleged former classmates.

SM Entertainment is expected to debut its new boy group in the second half of this year, as per the Koreaherald.

Fans are raising curiosity if "pink hair boy" or Hyunjun will debut with them.
