Ground control to Captain Andor, AKA the Rebelcaptain Astronaut AU no one ever asked me to make

The year is 2032. It’s the end of construction to extend
the International Space Station with a top-of-the-line rotating habitat, bringing the old station into the new age of
space travel. Captain Cassian Andor has been on a solo mission to the
ISS to install the Key To Station Operations, an AI more commonly known as
K-2SO, whose job it is to manage the newly expanded station, as well as assist
the crew when necessary, enabling the entire station to be run by only one crew-member
at a time. 

To put the new features to the test, Cassian is to leave
the station in the hands of Jyn Erso, a British astronaut send in from the ESA.
She arrives two days before Cassian’s planned departure to earth, and the
widely different pair take an immediate dislike to each other.

Unfortunately for them both (or perhaps fortunately), due to a critical error in
K’s programming, he accidentally ejects Cassian’s return pod five hours too
soon. The capsule is sent floating off into space unmanned, and Cassian is
stuck on the ISS with Jyn. His only option is to wait out Jyn’s two-month
mission and take the planned descend back down with her. Suddenly, they need to
somehow find a way to get along for a total of 64 days.

There’s room enough on the station for them to avoid
each other most of the time, but for some reason they never do; instead they
get in each other’s space, his hand on her elbow when he drifts by her, her
eyes always finding his as the first thing when she enters a room. Cassian
isn’t sure when the feel of her loose hair tickling his throat as she floats by
stopped bothering him. Sometimes he’s not even sure if it ever really bothered
him at all. Jyn doesn’t remember when she started thinking of Cassian’s
discarded jackets left in her workspace as an annoyance and started seeing them
as signs of the kind of life she tried to leave behind on earth, but now longs
for.

Without realising it, they’ve both started closely orbiting
each other as surely as the station itself is orbiting the earth.

By day 17, they’ve both privately begun to understand that
maybe they aren’t as different from the other as they first thought. By day 34
nothing’s been done about it, but even two people as repressed as Jyn and
Cassian will have to snap at some point when pushed together in such close quarters…
