Ah, I think I see what you're getting at.
Definitely, Camilla and Tirria have some similarities in their backstories and hang ups, one feeling like she's not a proper member of her race, one being happy with her race, but scarred after a lifetime of mistreatment because of it. They both have major body issues, and I can totally see how they open up to the MC is very similar.
However, I think it is also worth mentioning that out of all the girls in the game, they are the only ones with this explicit problem (other than moments here and there for a few other girls, but in a world with as many distinct races as this, I don't think that's super unlikely).
What my goal is, and hopefully I can convey in the future, is that this is only part where their "routes" intersect. Now that the MC is "dating" each of them, I plan/hope that their stories will be going in much different directions, and as girlfriends, they will feel very distinct.
With regards to the futa stuff, that could also be a way to approach it for some of the girls in the future, assuming the player has that specific content enabled. Definitely planning to iterate on all the transformation systems in the future, and as the game progresses.
For the Camilla thing: honestly, I didn't even think of that at the time. She'd most likely refuse, especially at first (no way she'd want to live somewhere bustling, at least right off), but it could be a point that she grows into, and having the MC at least offer would be a decent character moment.
Once again, thanks for all the feedback, scripting for the game can be a very isolating experience, as with this genre, many people don't want to engage beyond just downloading and experiencing it.
