Bond with nature in this charming expansion pack means...

I think they just referenced an overall style of the pack, but maybe it's fairies. I don't know.
I feel like it's not farming, but more like cottagecore/countryside living, maybe with more off-grid options. I hope that bonding with nature means wildlife, but I'm not sure... They certainly have to do something new to make this pack stand out, we have quite a lot of eco/off-grid themed options already.
