SI-JUN-RICKY, a TOO vocal position trainee, drew its own charm by creating a deep atmosphere.

At noon on Sept. 4, personal teaser videos for SI-JUN-RICKY, which dreams of debuting as a TOO, were posted on various social networking sites, including World Klass' official V-Live and Twitter, Facebook, and Instagram.

The SI-JUN emphasized its dominant look, making frames with big hands that show a manly line. The more you look at it, the more curious you are, the more interested you are.

RICKY tapped the hearts of his fans with his deep eyes and a gentle smile. He showed a variety of facial expressions for about 20 seconds, revealing his unique presence.

Global idol project group Ten Oriented Orchestra means "an orchestra oriented toward 10 Eastern values." Twenty trainees from Korea, Japan, China, the U.S., and Australia will compete to make their debut as TOOs, with only 10 trainees taking the chance to make their final debut.

The new concept idol-raising reality show "World Klass," which will portray their survival process, kicked off its first promotion at the "KCON 2019 NY" held in August and 20 trainees were first unveiled through "Futcher Idol Stage" on "KCON 2019 LA" in August. 

Meanwhile, 'World Klass' will premiere on Mnet channel and V-app in September.
