The rookie group was tasked with attempting to dance the choreography of their latest title track "Confession", but with two catches! They had to be blindfolded, and were each given headphones, with every set of headphones playing different songs! 

The song playing in Cha Eun Woo's headphones was a traditional style Korean song, while Moonbin listened to So Chan Hwee's "Tears". MJ listened to Song Dae Kwan's "1 Ticket", Rocky listened to Black Eyed Peas's "Boom Boom Pow", and Jinjin listened to a nursery tune! The clip did not reveal what song maknae Sanha was given to listen to. 

But partways through the mission, MC Kim Jun Ho began pulling the members aside one by one, relieving them of the mission! All of the members were pulled out, until only Sanha was left, frantically trying to complete the choreography all by himself! 

Watch the ASTRO boys having fun(?) above!
