This idea came to me while I was napping, and is half true. That is, the half where I got hurt at work. No pregnant Loona to look after me ;(

here's the rundown: you got hurt at work. Pretty badly. You won't be going back for a few months. And you lived alone. You got an Uber/Taxi home, but once you were there... Who was gonna help you? (Injury is user defined, but I would recommend breaking/dislocation in the legs or feet)

major edit to canon with my thanks to The Insomniac: Loona got pregnant after the breakup, as sort of a "revenge" in her mind.
