SM Entertainment has unveiled a new pre-debut project for its next-generation boy group. The agency confirmed that it will partner with production company EggisComing for Reply High School, the first reality program dedicated to SM’s multinational trainee team, SMTR25.
The show brings together 15 trainees, including known members of SMTR25 alongside previously unreleased trainees. The lineup includes Nicholas, Kassho, Justin, Hyunjun, Woorin, Hanbi, Songha, Kachin, Sadaharu, Tata, Daniel, Haruta, Hamin, Charlie, and Jaewon. For many of them, this marks the first time stepping into the spotlight.
The concept of Reply High School is rooted in a time-slip format. The trainees will enter a fictional school designed to help them “find answers to their debut.” Divided into classes inspired by the 1990s, 2000s, and 2010s, the members will immerse themselves in the music, pop culture, and lifestyle of each decade.
Through daily lessons and communal living, SMTR25 will gain insights into different cultural eras while reflecting on their own growth. This nostalgic setup not only references Korea’s beloved Reply drama franchise but also connects the next wave of K-pop talent with the history of modern Korean culture.
SMTR25’s appearance in Reply High School comes after a year of growing exposure. The team was first introduced in January at the SMTOWN LIVE concert in Seoul, a special stage marking SM’s 30th anniversary.
The group later joined the global SMTOWN LIVE tour, performing in Mexico City, Los Angeles, London, and Tokyo. They also drew attention through the SBS program K-POP The Beginning: SMTOWN 30, which presented them as one of the agency’s most important new projects.
Production for the reality show is led by PD Shin Hyo Jung and writer Kim Dae Joo, best known for their work on The Game Caterer and Nana Tour with SEVENTEEN.
SM Entertainment emphasized that the series is being developed for a global release. Scheduled to air on a worldwide streaming platform in the first half of 2026, the program is expected to reach audiences far beyond Korea.
