Looking forward to it dude, I see great potential in the project. Is Olivia an option? Also interesting to hear there will be more women. Or woman I suppose if it's just one more. Best of luck to development.
The core story will involve the main girls which will all have their character arc and multiple scenes, there will be some npcs you can shoot your shot at tho. Most likely the Olivia content won't involve the main character since they're related.
