Nah, no heads up required. Fuck 'em

Why do we need to give
heads up? Just don't advertise it as being a upper-case-R
Romance and it's fine...
This would be Romeo & Juliet
except Romeo has to kill Juliet. This is what I mean about subverting tropes. The star-crossed lovers dying in each others arms is a trope.
So subvert it. Absolutely have Romeo murder Juliet, or Juliet murder Romeo (#feminism). This is how we find our originality. What makes my French Revolution guillotine story a love story is that it's still about people in love
. Maurice still loves Francoise.
He is, however, forced into executing her by other circumstances. These can be honorable circumstances. Perhaps he feels a sense of duty?
Subvert what duty means. Even if they aren't honorable, even if they are immoral, they can at least be relatable. Have Romeo kill Juliet because he wants to be a revolutionary hero and finally be respected.
Subvert what respect means. Then, how about some irony? He really doesn't give a crap about the ideology, he just wants to fit in.
Subvert what ideology means. These are relatable issues, and they could easily be imaginable in a Revolution. There are so many different iterations you can use on this idea and you can apply it to numerous historical periods, right up to the point where credibility fractures.
Heck, take it as far as you want. Have a detective story on the spaceship, have a gay romance set in World War One trenches. The reason
The Shape Of Water is a more romantic movie than your average boy meets girl is because it's about a weird woman and a weird mutant creature in a horrible dystopian society. The reason
Brokeback Mountain is a great romance is not because of the homosexuality but because of the context in which the homosexuality happens -- cowboys on a mountain. There's no room for straightforward 'handsome boy meets handsome girl in Paris, rubs flowers on her nipples and makes her orgasm' type baloney in literary fiction anymore. Unless the handsome boy is actually a eunuch, handsome girl is actually a boy, or Paris is inside of a snow-globe.
Subvert it.
