I'll rate the anime in these categories:
1. gayness 2. complexity of the main characters 3.relationship
4.overall feel
1.VERY GAY, gayness everywhere. good representation, characters obviously know that love between two girls isn't the "norm", but other than that it was just a series about regular drama surrounding love, just like it would look like if they were heterosexual.
2.I this the characters were definitely complex, but the main character, Yuzu, lacks interests and any other "life" accept for the romance. Mei on the other hand is a very complicated person, with a life goal, supported by a backstory and contradicting feelings-like a real person.
3. I personally don't really dig the romance between them. at first i think they enter this sort of grey area, as it would be if they were step sisters, but soon after that i find Mei's behavior annoying, because it was the same thing over and over, yet Yuzu's reactions were normal and understandable, considering Mei's actions. Just when they both get the chance to explore relationships with another person, it pained me that Yuzu didn't even consider that option and put her admirer aside! That is a great plotpoint the creators missed, because without it, the existence of that character was actually unnecessary and didn't add anything to the main plotline accept for the fact that Mei got a little jealous one time. Shame!
4. Overall it was a show based on the trope "WHAT ARE YOU DOING STEP BRO?". I'd say it's ok but not very good.
