To me, the biggest "stage presence vs real person" is Jong-in of Exo..
Dude slays freaking hearts on stage...yet makes me want to cuddle him and give him fried chicken when he's off stage.....the fuck? lol
Here's a cute video that shows Kai vs Jong-in.
Body rolls are DEFINITELY Kai...the cute lauhging at Ko Ko Bop is all Jong-in...
