Yeah, Autumns stuff escalated really quickly. At least the cum covered and writing parts. I'd be surprised if the next update doesn't contain her first sex scene(s).
That does make me think of whether or not her sister will be involved in the story as a side-girl eventually. Most of the girls have a dedicated side-girl that lives with them. It'd be an interesting plot to have Autumn convince her that sex isn't bad or immoral, as long as you do it with someone who loves you.
And now that has spurred more thoughts. What if Autumn and her rebel against their parents, which ends up with MC buying the cafe from them? It could then serve as a job for the sanctuary elves and an extra source of income. If MC is going to change the world, he needs more resources than just a hotel.
And now something completely unrelated ( well, mostly). We're pretty far into the game, yet the last main girl hasn't moved in yet. I know Runey has talked about this, the wheelchair girl is the one that comes to mind. But I assume it'll end up being one of the side-girls, it's probably too late to start from scratch with a brand new girl.
But the last main girl being a former side-girl gave me this idea. What if, instead of promoting a side-girl into a main, all the side-girls just move into the room? Think of it as a dorm room. Bunkbeds, them sitting around chatting with each other, doing their homework ( or not ). The introduction of the college girls ( who already sit around the sauna area ) seems like a natural fit for this idea of mine. They already live in a dorm, so why not give them a nice dorm with a bar downstairs? They can still function as side-girls, they just get their own room unlike the others so far.
