With its first airing on Mnet and Naver VLIVE on Oct. 4, trainees of "World Klass" shot at global fans' tastes with unconventional moves even before their debut.

The 20 trainees, who dream of making their preliminary TOO(Ten Oriented Orchestra) debut, attended the "KCON 2019 THAILAND" held at the Impact Arena & Exposition Center in Nonthaburi, Thailand, on September 28 and 29.

The "KCON" is the world's largest K-Culture convention where visitors can experience K-lifestyle such as K-Pop, K-Beauty and K-Food.

Preliminary TOO trainees, who took the stage for the first time at "KCON 2019 LA" in August and took a snow stamp, showed a strong presence on the Thai stage, following LA.

The preliminary TOO trainees were divided into two teams to stage a pre-show concert, and the first meeting with Thai Infusionist FROM NANA within the "KCON" convention was held to talk and stage. In addition, the company has offered exceptional promotions even before its debut, including a Future Idol stage, high-touch events, and photo events, drawing explosive reactions from famous Thai Infusion and local fans.

Among them, hosting "KCON 2019 THAILAND" began reviewing the 0th chart, the first screening of the World Klass Committee to select TOO members on Friday, and 1,000 "World Klass Committee," which has ranked high in chemistry among World Klass VLIVE channel followers, is being reviewed.

Meanwhile, the Global K-pop Idol Growth Diary "World Klass," which boasts a super-luxury class only with vivid scenes, previews with various mission planes and pre-released video, will premiere on Mnet and Naver VLIVE on Oct. 4.
