I'm glad that other characters are acknowledging Kazuya's talent in getting this movie together. And it wasn't just the crowd-sourcing that he pulled off.
Maybe he'll even get some self-confidence in himself. I definitely can see him getting requests to assist with other people's movie projects. Yaemori will probably pop up again, for fund-raising help as well as relationship pushes.
I was hoping for more progress, but this is some.
AFA Umi, I'm not too surprised with how he behaved. We know very little about him. We know that he's friends with Chizuru, he's an actor who is out of college, and . . . ? I think a lot of us were projecting preconceptions on who he was.
He was attracted to Chizuru, but that's not surprising. She turned him down, and he wasn't vindictive. I can totally see him as being supportive of Chizuru's friends, and that he's moved on from her rejection.
