It sounds like a Prince song from the early 80s.
But the video, oddly, does not take advantage of this. It is very much "Bros before Hos." The boys spend much of their time looking fabulous and ignoring the women...except for Changmin, who keeps putting the tips of his sunglasses in his mouth UNF UNF while eyeing the ladies. Everyone else looks miserable until the end, when the OT5 are reunited and it feels so good.
