It would be irresponsible to discuss xenophilic [WORK] romance without addressing its common failure mode: the reduction of the alien partner to a plot device or a static allegory for a human minority. The "Born Sexy Yesterday" trope (popularized by Pop Culture Detective) is a prime example. Here, the alien is a powerful, naive adult who must be taught about love and the world by the human protagonist. This is not a romance of equals; it is a pedagogy.
The romance cannot exist in a vacuum. There is a job to do. Whether it is closing a merger, surviving a zombie outbreak in the office, or launching a satellite, the work goal must intersect with the relationship goal.
