SM Entertainment’s highly-anticipated rookie collective SMTR25 has dropped a 30-second teaser featuring their cover of Girls’ Generation’s iconic 2007 debut track ‘Into The New World’, setting the stage for their pre-debut reality show ‘Reply High School’.
The series, premiering at 8 PM KST on February 13, transports the group divided into ‘90s, ‘00s, and ‘10s cohorts to fictional Woojeong High School in a time-slip concept. Unlike traditional survival programs, ‘Reply High School’ will follow a no-elimination format, focusing on members’ growth as they recreate landmark K-culture moments through school activities, fashion trends, live performances, and campus festivals.

Production is helmed by the creative team behind tvN’s hit travel series ‘Nana Tour’, promising unfiltered footage of the rookies navigating both nostalgic throwbacks and modern-day challenges. Early social media buzz has already highlighted member Hamin’s striking screen presence, with fans celebrating the heartfelt tribute to SNSD a cornerstone of SM Entertainment’s legacy in shaping global K-pop.
Industry sources confirm the show will be available on major international streaming platforms with multi-language subtitles, aligning with SM’s strategy to launch the group as a global K-pop act from day one.
