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.
^if memory serves (though it's been a few years) it's basically an elaborate kinetic novel at core; your only actual choices are in regards to the particular order you view the vignettes.
