• SM Entertainment is planning to debut a new trot idol group, which will feature trainees from their SM Rookies program. The group will be the first trot idol group under the SM Entertainment label, marking a departure from the company's typical focus on K-pop groups.

• The new trot idol group is expected to bring a fresh and unique sound to the K-entertainment industry, as trot music is a traditional Korean genre that has not been heavily explored by major K-pop agencies. This move by SM Entertainment could help introduce trot music to a wider audience and potentially revive interest in the genre.

• Details about the specific members of the trot idol group, as well as the group's debut timeline, have not been officially announced yet. However, the article suggests that the group will likely feature some of SM Entertainment's most promising trainees, who have been honing their skills through the SM Rookies program.
