If there is any part of the lore you would like to change (or take issue with), everything's negotiable. I'm more interested in the romance than in the sci-fi.

Btw, the main reason I'm going with a cliche "arranged marriage" trope is it neatly packages two solutions together:
1. It allows us to tell the story of a couple already in a committed relationship. There are quite enough falling-in-love stories in the world and not enough about people trying to maintain an existing relationship.
2. Our characters can't know each other already. How can they when the players don't even know each other? We'd have to retcon and go like, "Of course, she knew he tended to do that." The alternative? 7 years together, and they barely know each other? Not buying that.
