The "dance line" members of KBS2's '1 Night, 2 Days' have decided to put their skills to the test once again, with the #ShyDdoongChallenge!

This past weekend, comedian Moon Se Yoon made his official solo artist debut with her alter-ego BUKKUDDOONG, releasing his 1st single "Shy Ddoong" feat. Ravi. The track was written and composed by Ravi and released in collaboration with Ravi's label GROOVL1N. 

In light of the release of his first single "Shy Ddoong", BUKKUDDOONG has also launched the #ShyDdoongChallenge on TikTok and other SNS platforms! The comedian has so far enlisted the help of many of his celebrity friends to promote his challenge, and this time, it's his fellow cast members over at '1 Night, 2 Days'!
