Speaking about Ayvex, i’d personally would love her to be gender-flippable though if you are indeed implementing some romance aspects in it. Based on the interaction in chapter 6, she sounds badass and amazing.
Also, just like @Lan, i found the exact same false quotation marks placements and also in one scene where Sorin asked for “beseechment” or something from Serena, and there were options for us to either stop the abuse hurled at her by doing it physically, verbally calm down the situation by representing for her, and one other option i forgot and the typo was you wrote Sorena instead of Serena. Forgot to take a screenshot of that particular typo so i’m just describing it out lol. But other than that, the flow & plot of the story is really good 
It’s also very creative of you to create this world & lore where Birds function like humans but they have more of like “The Purge” ritual happening every month lol
oh, and before i forget are Sorin & Conk a potential RO as well? Because i remember Sorin saying he’s got a wife but then you said
Or is that just a statement?
