https://twitter.com/taedonyzlove/status/1015778564484915200 Shinya-san the pianist who played the beautiful music for Haru yo Koi in Fantasy on ice talked a little about working with Yuzu. (basic translation)
Yuzu was very passionate about the piano and the music when talking to him, he felt he was talking to a fellow musician. From the arrangement of the music, things like, can you play it more like this? Usually skaters use pre-recorded music, so no matter how many times you skate, the timing is the same. This time, the music is live so it doesn't work like that. Instead of thinking of it as a risk, after each performance, he said things like, we can pull that out a little more, we can put more feeling there, and they brushed it up each time, by the last performance it was 30 seconds longer.
He was able to enjoy it and he's really a perfectionist.
I said, since you know so much about music, you could make it yourself!
And he said, 'in music and choreography there are professionals like yourself, that I want to learn from, but I wouldn't think to stand in your shoes.' I think it's wonderful that he got the People's Honor Award.

A little bit from before the above clip. Shinya is a funny guy! "I've never played for an audience that ignored me like this....I'm like, I'm here! I'm Here!"

"I was getting to a quiet part in the music, and this is a really good part! And Hanyu does something and there's a huge reaction, and I'm like LISTEN!"

) But he says that Yuzu as very caring and mindful of his Sempai. And that he has a will that's stronger than anyone else'.
