Here's an idea: the history of romance.
Go back to the medieval era where romance was all economics, then the fantasy of romantic plays and books, then transition into modern society where romance has become a trial-and-error game where you mix and match with different people until you find someone with whom you can grow old together with.
Or something like that.
