I see that Ayame is starting to wonder if she really likes Takasago or not... It doesn't feel that way, at least to me, and maybe that's to be expected since she has very high relationship standards, like her sister and Haryu / Inota and Chinatsu.
Also, her current boyfriend is always very distant from her and doesn't do anything with her - like, asking her on a date - and doesn't try to get closer to her world and get involved, in Brazil we call guys like him a "pau mole". Strangely, he feels bad about it, but doesn't say anything, and this lack of communication is a bad way to deal with it, so it will probably build up and they will break up, bacause of it.
So, it seems to me that this dynamic will be explored based on the premise of lack of trust, both for Ayame/Takasago - Kyo and Inomata/Chinatsu and for the new neighbor.
It will work better for Ayame, because Inota and Chi seem much more mature about their relationship, also we will finaly see progress for Haruto and Hina.
