SM Entertainment’s multinational team of male trainees, SMTR25, will make its debut through an entertainment program on Mnet.

Mnet announced today (the 23rd) that the new reality show “Reply: High School” (응답하라 하이스쿨), directed by Shin Hyo-jeong, Jang Eun-jeong, and Byun Soo-min, featuring SMTR25, will premiere on Friday, February 13 at 8:20 PM KST. Along with the announcement, the main poster and a performance teaser were unveiled.
“Reply: High School” follows the 15 K-pop trainees of SMTR25 (Hanbi, Songha, Daniel, Hyunjun, Hamin, Jaewon, Woolin, Nicholas, Kassho, Justin, Haruta, Sadaharu, Charlie, Kachin, Tata) as they enroll in a fictional school called Woojeong High School. Through a time-travel concept, they revisit K-culture from the 1990s, 2000s, and 2010s, searching for the answers that will lead them to their debut. The program is led by PD Shin Hyo-jeong of Egg Is Coming, known for Nana Tour and Nana Guesthouse, and will highlight the trainees’ innocent, youthful daily lives, contrasting with their on-stage charisma.
In the newly released performance teaser, the SMTR25 members, dressed in school uniforms, reinterpret Girls’ Generation’s “Into the new world,” an iconic song from SM Entertainment. Their powerful yet refreshing performance, filmed in a wide open field, perfectly captures the youthful atmosphere and team spirit the show aims to showcase.

Filmed in a 24-hour observational format, the reality show divides the participants into classes representing the 1990s, 2000s, and 2010s. Each group will experience the trends, music, and school culture of its assigned era—such as sports days, school trips, and festivals—offering an intergenerational immersion and unexpected interactions.
“Reply: High School” will premiere on Friday, February 13 at 8:20 PM KST on Mnet and Mnet Plus.
