While strolling around the streets of Busan with YG producer Kush and other YG staff members, Taeyang ran into a group of dancers enjoying music and showing off their moves in a dance battle. The YG staff egged on Taeyang to participate. The idol star hesitated at first but gradually grooved to the beat. He then confidently wowed the audience with his smooth moves, all with concealing his superstar identity with a mask.

In the interview in the studio, Taeyang commented, "Honestly, a lot of thoughts ran through my mind after then. I was able to relive the feelings that I had before debut where I enjoyed music and dance without minding who I am."
