Good point.

I didn’t even think of it at the time, likely because it was written well enough that it just felt natural, but in retrospect, that whole scene was likely a deliberate strategy to give an important side character some final screen time. And deservedly.

And yeah - I definitely agree about Yui. I thought she was an especially good imouto character but has been underused in general (though she did get a chance to shine in the chapters with her and Suzu, and the whole thing about Chiaki’s little brother crushing on her). It’d just be nice to see her get a moment, and possibly even with their mom.
