Thank you so much for all the kind words and for writing such a detailed comment!
We're really happy you liked the demo and yes, that's the same Snow as in //TODO: today!
In the full game you'll be able to befriend pretty much all of the main characters of the faction you're in and some of them will be romanceable as well (although that's not the focus of the main story). And as far as Karin goes, well, there might still be a chance some day...
Thanks for playing <3
