So if "Yesterday" wasn't enough Junsu followed it up with a dance track featuring Giriboy. Overall it was a pretty good video. The choreography was cleeeeeaaaan. The only thing I'd change about the video would be the lighting. It was kind of all over the place. Other than that it was pretty good. Junsu looked SEXY AS SHIT!!!!! Lawd I'll never have another UB. He is it. Anyway, if you haven't seen it I'd highly recommend it.
While you're at it, I'd recommend "Yesterday." The contrast of themes and sounds is amazing. Both songs and videos are really good.
If you'd like to watch the video along with the lyrics you can do so here.
