I find that video to be a bit strange.
It seems like they decided to film that spontaneously and Ayu had to make it up as she went along in English.
I think she did okay, her English might seem better if she talked a little slower and maybe did a few takes.
It would be good to understand that no matter what, learning another languages is very difficult. It doesn't matter what language or what you speak natively. Learning a second language is a HUGE undertaking. People lie when they say x language is so easy. They are just trying to look smart. It may easier for some but never easy in general. I mean just think about it, learning a wholeee different way of speaking and understanding. You have to change the way your brain works!
