TVXQ wants you under their skin... and they spell it out too

Now this is interesting.... We all remember the controversy over TVXQ's lyrics in their song, "Mirotic", and now months later, Cassie's are speculating that in the dance to the song, the sexy stars actually spell out "skin" together. Perhaps if it were one or two pictures, I would say that the Cassie's are spending a little too much time in front of their computer... but because they got together 5 separate pictures of 5 separate performances, I'm not sure what to think. And since, we all know SM Entertainment is full of masterminds - like how there really is a "secret code" behind TVXQ's "The Secret Code" album - I wouldn't put it past them. Though none of this matters to me, because regardless, I still want to get underneath TVXQ's skin anyway... but what do you think: crazy Cassie's trying to find something in nothing or one of SM's genius moves?
