Na Young-seok’s Team Joins Forces with SM Trainees… Launching “Reply High School”



SM Entertainment (hereafter SM) and production company Egg is Coming are introducing the first standalone reality program for SM’s male trainee team “SMTR25.”



According to SM on the 17th, the time-slip growth variety show “Reply High School,” co-produced with Egg is Coming, will feature a total of 15 participants—including some members of SMTR25 and unrevealed trainees (Nicholas, Katsho, Justin, Hyunjun, Woorin, Hanbi, Songha, Kachin, Sadaharu, Tata, Daniel, Haruta, Hamin, Charlie, and Jaewon).
The trainees will enter a “school” in search of the answer to debut, where they are assigned to classes themed around the 1990s, 2000s, and 2010s. Through classes and daily life, they will experience the emotions and culture unique to each era, embarking on a journey toward the day their dreams are answered.



SMTR25 is a multinational male trainee team under SM, first unveiled at “SMTOWN LIVE 2025” in Seoul this past January during a special stage celebrating SM’s 30th anniversary. Since then, they have also performed at SMTOWN LIVE concerts in Mexico City, LA, London, and Tokyo.



They were also introduced as next-generation artists who will lead the future of K-pop in the SBS special program “K-POP The Beginning: SMTOWN 30,” drawing explosive attention. For this reason, the upcoming show is also expected to generate strong global fan interest.



This program, which takes viewers on a journey through the historical timelines of K-culture, is being produced by core creators Shin Hyo-jung PD and writer Kim Dae-joo—known for tvN’s “Youn’s Stay” and “Europe Outing.” It is scheduled to air on a global platform in the first half of 2026.
