Love the casual outift!

And, yes, her English has definitely improved.

And about when she said, "I'm so tired," I didn't interpret that as mean. I found it cute! And she said it in a nice way. Like, "Ooh, what a day!" ^^
I just think it's so funny in the first video. At about 0:10 she's walking with Stan, the other bodyguards are kind of spread. Then at 0:12 she willingly walks over to the fans and the bodyguards just *swarm* like the friggen SWAT team.
I understand why the bodyguards swarmed between the fans and Ayu, and I think that it's great that she willingly went to the fans on her own! ^^ I just love how one can make it look like...
GUARDS: Ayu, we have to go here at this time.
AYU: Yeah... okay... Ooh! Fans! *runs over to them*
GUARDS: Noooo!!
