SSR - Thoughts of You, Carried on Wind

How do the different books/routes work in Ayakoi? I understand that each one centres around a different boy, but the "secondary" characters that are common to every route (Akiyasu and Aizen) act really differently in different routes. I get that different plot points trigger different actions from them, but in Koga's route Aizen seems worse that Akiyasu, while in Ginnojo's route Aizen is super respectful and sweet. I was really confused when I read the different routes because I didn't know what to think anymore.

Akiyasu is fairly consistent even if he is less "bad" in Aoi's route compared to the others, but I just don't know what to think about Aizen. His different decisions (to apologise versus to threaten Futaba) are too opposite for me to see the reasons behind them, other than to make his character do different things in different routes. But that prevents me from understanding who he truly is as a character.

What do other people think of this?

Wasn’t quite sure where I should put this (because technically he isn’t a part of any particular faction) so I thought I’d post it on its own
