Global K-dance Mission begins this week. The crews must come up with choreographies for one of the K-pop artists' songs. The given artists are BTS, EXO, Big Bang, and SEVENTEEN. Vata, the winner of the previous mission, gets to pair up the crews and choose the songs. They must also include a choreography-copying section where each crew gives the other crew a choreography to copy. The losing crew of Copy Choreography Challenge will become the backup dancers for the winners. Which crew will become the backup dancers and bear with the humiliation? Stay tuned to find out!
