Thanks for explaining. I'm a native English speaker who grew up in a (fairly?) strongly guess culture, and I'm still really surprised that anyone would find this rude or threatening. It's interesting to see the very different interpretations.
"I hope this works out /so/ we can see each other!"
It's not physically threatening, but this makes a strong implication that the relationship will be potentially damaged by refusing to comply with the request. Consider this alternative, "I hope this works out. It would be great to catch up either way!" This makes it clear that the relationship will not be harmed if this doesn't work out.
Yes, I am reading into things, and I was raised as a Guesser but consider myself bilingual. IMO being an Asker is fine, but if you hold the relationship hostage, it's Demanding, not Asking.
I can't speak for my culture generally, but my personal interpretation of the quote is that it is fairly neutral in its current form. I read it as saying that cohabiting will make it easier for the guest to see the hosts.
That is to say, I interpret this:
"I hope this works out so we can see each other!"
As this:
"I hope this works out because I would like to see you and by living under the same roof for a short time we will be able to see each other!"
I have to say, though, that this might be dependent on my relationship with the person. If I like them, I'm more likely to have the generous interpretation of this phrase.
