Songha

Songha (송하) is part of SMTR25, the public trainee unit SM Entertainment is using to turn its next rookie cycle into an active audience storyline. That matters because SM rarely gives trainees this much runway before debut. Through official social channels, international SMTOWN stages, and Mnet's Reply High School, Songha is already being introduced as a live prospect rather than a hidden practice-room name.

The 2004-born trainee sits in a different position from the youngest SMTR25 members. He arrives with a profile that reads older, steadier, and closer to the front edge of an actual launch window. That makes his place in Reply High School useful context: the show is not just promotional filler, it is part of how SM is letting the market read personality, chemistry, and readiness before locking in its next debut team.

For now, the confirmed record stays tight. Songha is a South Korean trainee under SM, a visible member of SMTR25, a cast member on Reply High School, and part of the 2026 single We Go Up. In a company where pre-debut visibility is usually rationed, that combination already puts him on the serious-watch list.
