Yes, that's what I noticed too. I was already impressed by how good his English has become when he did his interview with CBC. I think Yuzu's English has improved even more.
I'm sure he's been practicing and working a lot on his English skills. He's probably been taking lessons with private tutors and such. Finally, Yuzu's intelligence, eloquence and ability to formulate and express deep and complex ideas have also become obvious when he speaks English. Trust Yuzu to become the best at everything he does!
And the way he looked! OMG! Being the king he is, he actually made the effort to dress up and style his hair nicely. Yuzu looked absolutely gorgeous! He's becoming more and more beautiful.
And I wanna say thank you so much to all of you who organized this Yuzu skating party! It was a blast!
