Obviously, the intention is to build up Rachel throughout this beginning section, but it really falls flat when you build up a sister character as an LI, who was the MC's "best friend" before they had their falling out, but she's a massive slut who's taken god only knows how many dicks, including from the new best friend character. Up to this point, there's not even anything to be done about it, we don't even get the option to be mad at Fiona about it, the MC just says that she's over it and that's it. The whole point of Incest games is the added intimacy that is inherent in that type of relationship, which is why the MC even states that Rachel is her soulmate, but the intimacy is already demolished by the fact that she's as used up as a 2 dollar whore. Banging your sister isn't special if everyone is doing it.
