The use of color is brilliant, because the MV is shot with all of these bright and beautiful and bold colors and then all of them are desaturated just a bit in the editing, it's still this beautiful vivid scene, but it's just slightly vague and dream-like. The smoke and the chalk-powder and the feathers all give the MV an immediacy, a sense that the present moment (and the passage of time through it) is what's most beautiful. It's all very artsy an suits the song incredibly well, and besides, it's just plain fun to watch. It's also incredibly sexy, the sensual movements, the outfits, the skinship . . . all of it contributes to a great idea of personal liberation, including sexual freedom and comfort with that sexual freedom. It's great because very few music videos period, let alone the ones in Korea, express that not only is it okay to be a sexual creature, but that being so is not strange or special, it just is and we can just accept it with ease and comfort as an aspect of the world in which we live.
It's beautiful to watch and it looks gorgeous, so my only real complaint is the lack of an active narrative.
