Last week, the Cube artist appeared as 'Crane Guy' and performed Trouble Maker's "Trouble Maker" with 'Money Girl'. In the first round, 'Crane Guy' was able to outlast his competition by showing his groove and relaxed stage manner.

After reaching the second round, 'Crane Guy' continued to surpass all expectations by covering BTS' latest hit song "DNA". As soon as the song and his voice met, the audience and the panel gravitated towards the artist's voice which eventually led to him moving on to the third round of the competition.

This week, the competition continued as the 'Crane Guy' stood on the stage once more to sing Jung Seung Hwan's "The Fool". The panel got excited as soon as the melody came on and expressed how the song choices have been on point throughout the entire episode. For the Cube artist, however, this would be the end of the road as he lost in the third round.

After learning his loss, it was time for the artist to reveal his identity. Once he did, everyone was shocked to find Pentagon's Hui, except DinDin who figured out who it was before the unmasking took place. DinDin said, "I knew from the beginning. I recently filmed something with Hui and during that time, we spent a lot of time talking about music. After that, I listened to all of his music and found that his music sense was amazing, and during his duet performance, I heard him make his signature sound that helped me confirm it was him."
