^^Have you seen how awkward she gets when someone asks to marry her? Or when MitsukiBB screamed out, "I LOVE YOU SELEN!" at the end of the Apex hide and seek? Selen is pretty weak to this kind of stuff lol
I wasn't all that interested in Ano for most of my first playthrough, but I warmed up to her after I learned that she could see(but not hear) the kindred spirits late in the game, and played some of her POV scenes. I still prefer the Yuna/Hina ship, and while a Yuna/Ano ending might be nice, I'm not sure how they could incorporate it given the Daily Planner system lets you jump around between scenes.
It's definitely not semi-platonic, but calling it an eroge seems like an exaggeration. The sex scenes are very much not the main focus, compared to the romance.
But this ain't "meaningful looks" or "even though it's another girl" yuri. They's gay.
