You'll get a lot more yuri undertones in the manga and the novels. In the game you can see some of that in the special SID events.I'm totally okay with doujins, but yuri in anime is my jam, you know? Even subtext get's me going. I heard that the anime doesn't really have much NozoEli (apparently Eli is paired up with Umi?)
The anime doesn't have as much. But since you like NozoEli, you can just listen to Glass no Hanazono and assume the couple is pretty much as official as it can get without going full yuri. Then you watch the anime and make your own interpretation of what they are doing when they go have parfaits together.
I watched that and now I want to play Toys DriveThere are too many videos too watch and not enough time, still need to watch the rest of that Milky video.
