This game is very well written, and the visuals are great. To me, the Anni story was, to my surprise, the most relatable and emotionally charged relationship. It's not just a dramatic backstory, but there are a lot of conflicting emotions on both sides.
So I was quite heartbroken when the Anni arc came to an end, and the relationship has now pretty much disappeared. First Anni was all over the MC, missing him, craving his affection; they were sleeping together, cuddling. She learned to give massages just for him. Then the date, the fight, and finally them making up and admitting their feelings. Afterwards, nothing... once the MC mentions "thank god Anni is not sleeping here" when fooling around with Sky. But why is she not there? After the move they also don't share a room anymore? That's quite strange, looking at how their relationship had developed just before that. Having the Anni relationship abruptly end kind of soured the Moon arc for me. The story with Moon Chi is great, but it felt like Anni was swapped out immediately...
In chapter 2 there is also almost no physical interaction with Anni. There are a few texts, but beyond that, there is zero intimacy. This stings and made me much less interested in Emma's arc, even though it was a really interesting story.
As a side note, Anni was made the queen of the harem, but since that event, this has been completely forgotten... which makes the decision kind of meaningless.
I'd love to see the Anni relationship come back in the remaining updates, even when it's not always the primary focus of the story. In my save game she has 17 relationship points, far more than anyone else, and still apparently it doesn't mean much.
