SM Entertainment's multinational male trainee team 'SMTR25' will appear on a variety show. On January 23, Mnet confirmed the premiere date of the new reality variety show 'Reply High School' (directed by Shin Hyo-jung, Jang Eun-jung, and Byun Soo-min), featuring 'SMTR25,' for February 13 at 8:20 PM, and released the main poster and performance teaser.

'Reply High School' is a time-slip reality variety show where 15 K-pop trainees 'SMTR25' (Hanbi, Songha, Daniel, Hyunjun, Hamin, Jaewon, Woorin, Nicholas, Katsho, Justin, Haruta, Sadaharu, Charlie, Kachin, Tata) enroll in a fictional school called 'Ujeong High' and experience K-culture from the 1990s to the 2010s while searching for the answer to their debut.

The production company is Eggs Is Coming, with PD Shin Hyo-jung directing. PD Shin has experience directing programs such as 'Nana Tour' and 'Nana Minbak.' He plans to delicately capture the innocent and fresh daily lives of the trainees hidden behind their charismatic stage presence.

In the released performance teaser video, SMTR25 members dressed in school uniforms reinterpret Girls' Generation's iconic song 'Into the New World' in their own style. The video features a powerful yet refreshing performance set in a vast field, naturally revealing the fresh atmosphere and teamwork of the K-pop trainees portrayed in 'Reply High School.'

This program will be conducted in a 24-hour close observation reality format. Each class member will experience trendy items, music, and school culture (sports day, school trips, festivals, etc.) from the 1990s, 2000s, and 2010s, showcasing empathy across generations and unexpected chemistry.

The production team stated, "Please pay attention to the unique chemistry and reactions that arise when past K-pop culture meets current trainees," adding, "It will be fun to see how the nostalgic cultural codes that defined an era are newly interpreted through the eyes of today's youth."

'Reply High School' will premiere on February 13 at 8:20 PM on Mnet and Mnet Plus. This program is expected to establish itself as the most notable K-variety show of 2026 by combining Mnet's global network with Eggs Is Coming's directing capabilities.
