Don't want to rain on anyone parade but honestly, after the choice in June, what kind of moment does Ano and Yuna have ? Almost none and honestly Hina work better because of the whole childhood friend thing, it's more harder to deal with romantic feelings when it's with someone you know for so long instead of someone you know for a year. I readed the manga before hand so it was kinda cheating but even without that, I can hardly see how you can romance between Yuna and Ano. Beside the cheerful/serious pair wasalready taken by both Youka/Aki and Sasa/Umi so getting a third one would have been really unoriginal.
I literally spent days to make ano yuno together -_-
How thought ? There is literraly one choice for that and Ano barely show up after that and most of the choices not even concern her, even before the choice in June.
