I'm confused as well since I didn't add that tag. There is a mild gay joke in the early game that triggered someone and got then went wild about a gay tag, so I'm guessing it's thanks to him it got added by a mod that didn't check the game out. With like 400 scenes in the game all focused on girls, this game doesn't need the use of gay tag but feel free to correct me on that.
Then there's also an optional futa scene and I don't count that as gay either so I'm not sure what's up.
Sadly no because the workload is already heavy enough as it is. Good Paths are pregnancy filled and Dark paths are not.
The only exceptions are Lilly/Sarah/Sophia. Maybe later during development, we'll add more split paths for certain girls that are currently neutral.
I don't recall that ever happening, but early-game Nani stuff was made 2 years ago. If that's the case, send me a screenie and I'll change that. There is an optional bukake scene that doesn't involve cock sucking if that's the one you're referring to.
In any case, it's not a common theme at all because basically, you can always opt out of stuff that's not your thing.
Later on in the story, you can go way more vanilla or way more hardcore depending on your preferences.
If you're in doubt about the branch-off section, just check them both out because they're very different. I personally think it's fun to see the two different sides of the story.
I think you're probably right that early game Nani's story is a tad wilder than others girls. Her theme was supposed to be exhibitionism.
