Although it was edited out in the final music video, Kim Junsu also tried playing a dual role for a kiss scene. A scene where Kim Junsu, dressed in a female outfit, kisses the real Kim Junsu. The person who was the most satisfied with his acting (in that scene), was Kim Junsu himself. He was pleased as he said, “I am holding onto the footage. I think I look better in a woman’s outfit than actual women do.”
