Get a sneak preview of the idols on 'Secret Variety Institute'!

MBChas dropped a few preview videos ahead of the show's broadcast later on May 5 at 6:10 PM KST, one showing all of the idols coming together thanks toAkdong MusicianmemberChanhyuk's guitar strumming accompanied byHan Dong Geun's magical voice, singing "Let It Be"!

In another preview clip, AKMU'sSuhyunpicks out a card and asksBTOB'sSungjae,"When was the first time you came across 19+ rated content?"

Sungjae answered,"Around 5th grade?"then corrected,"Sorry, maybe 4th grade"! He continued, "We went to a class trip in 4th grade, and because we were all boys, one had brought the content with him, in the memory chip of his gaming device. We were like, 'What is this?' It was fascinating, and new."

Can't wait to see more? It won't be long until the show premieres in light of Children's Day in Korea, soon!
