Read the comments and you'll know you're not *_*;
It looks like they were forced into doing it.
I don't get people that're saying 'They were like that in the original video!' because, uh, they weren't >:
Bad posture and restricted movement wasn't a part of the original *_*;;;; Like even scenes where she was lip-syncing, in the original, the characters moved around a lot more. You could see their hair flying in those for heck's sake :'D Hate the scenes on the 'grass' too. Could've been filmed loads better, so their necks didn't look so fat. And lol @ terrible greenscreening ._.;
I swear, it must say 'april fools' in Japanese somewhere in there.
