Looking for something with language barriers, cultural misunderstandings and/or marriages of convenience/mistake

Basically title, only requirements is that it's slow-burn and not litRPG.

I personally think sci-fi works best for this, but I'm more than willing to be proven wrong and read another genre as well!

Spice is fine if it's one or two scenes at the mid/end of the book with love interest.

Poly/Harem and Mono are all fine.

Books that I've read already;
Vixen War Bride Doscher, Thomas J. (So good!)
Between Worlds Williams, J.L.
Of Men and Dragons Hayden, Steven
The Onyx Throne Hexx, Devon

Tried reading Iced Hearts ( Pirate Opotato ) but It went a bit too hard into the spice from the get-go and I'm not all that into amazonians (though, not a dealbreaker)
