It's in a separate scene. You have to visit Shuu in the restaurant again, I believe. Also: you can have the fanmeet in November? I thought that was only set in December 10? Did you play that in the demo, maybe?
Ah, I'll keep visiting him at the restaurant then, thanks! And hmm, welp, now I'm not sure. I think I did the fanmeet in December but it may have been mentioned late November?? And no, the demo doesn't go that far into the year. I'll just try to pay special attention to getting my fame up quickly when I reply his route.
