Muse A needs to get across the country to see family for the holidays, but has no car and can’t afford to fly. Muse B needs to make the same trip, but can’t afford that much gas and can’t do that much driving alone. Friends of friends connect them to make the journey together.
Bonus points for the muses hating each other on sight and falling in love by Kansas state, discovering they’re soul mates, realizing they were friends in elementary school, getting snowed in at a diner in the middle of nowhere, having to share a bed, one muse pretending to be the other’s SO for meddling family reasons, one muse not actually having family and spending Christmas with the other muse’s family, or the muses rearranging their lives in January/changing colleges/quitting jobs because they can’t bear to be apart. Oh, and mistletoe. Goes without saying.
