As always, an amazing update. But I think it's time for the dev to ease the reins a bit. I don't know if he intends for a harem ending or a single ending with each girl, but he needs to start moving in that direction. We're ten episodes in, and we've already seen almost everything with each girl. Yet every time the topic of love or anything serious comes up, they freak out and say things like "Omg, stop it, you're my cousin/nephew". And when the MC said he might try to get a real girlfriend, they all gave him death stares lol.
I get that this adds some tension and gives the story more weight compared to most games like this, but we've had enough of that by now. It's time to start building toward something. Unless the final ending he has in mind is Davie fixing his family while the MC moves far away lol.
Not with Stephanie, the little one wants everything

The others want things to stay a secret or "aren't ready".
I suspect only after you fuck Amelie, 3 main girls on parity, we will start to see story development.
How and why they discover each other.... what happens after that.
We did see the topic of how to handle Davie being brought up with Kylee, interesting solution using Mia and even Stephanie to get him off the scent, as boring as hearing "we can't" over and over is, it makes sense for the moment.
Also Stephanie already knows you are fucking Kylee... Kylee and Amelie don't know anything.
Stephanie has a history of being a blabber mouth so she might be the element that triggers the next step.
Again after we get those 3 on parity, which means...
Yes, she's the last one standing... i hope 11 brings the scene.
After that we should enter the next stage of the story.
