Once again I feel as if I'm reading an entirely different series than most posters here.
Mei's actions on citrus+ always have Yuzu as a priority, either by way of working towards a future that allows them to be together on their own terms or by looking for ways to show her affection. She is also more open about what is going on unless there are external factors keeping her from telling everything to Yuzu, like the exact details of the agreement she's looking to close with Arata's Family.
Besides the memes, I still can't understand why a lot of people are so invested in seeing Yuzu and Mei fuck. Mei's actions at the start of the story have been acknowledged as being wrong and Yuzu has gone multiple times about how she wants their first time to be special and happen at a point where both of them want them, but with all the emotional baggage Mei is just working out, that will take a while. Having them fuck right now would be awfully out of character for them.
That said, is interesting to see Yuzu feeling threatened like this, it hadn't happened since Sarah but this time there's the added pressure that Arata is a guy and thus, is more socially acceptable for Mei to be with him. Between this, Sayaka and Yuzu's friends, it seems that Sabu wants to treat the LGBT angle of the story more seriously.
And I love how Matsuri and Harumin seem to be together all the time now and Harumin has (reluctantly) taken over as Matsuri's guardian and slapping sense on her when needed.
