I don’t know for certain, but I know it’s probably true that…

• When little Ben Solo was a child he had an “imaginary friend”. He told his mother that this friend had eyes like embers and radiated sunshine. She only visited him when he was asleep. As he got older he convinced himself that it was just the imaginings of a child’s mind. 
• When Rey was a child she’d hear a voice calling to her in the night. It was always the same, a scared little boy calling her name. It frightened her and she chalked it up to the winds of the desert. 
• Kylo is absolutely in awe of Rey and all that she is. She is light, but she is not entirely kind. She’s not just sunshine, she’s an inferno and if she burns him alive then so be it. 
• Sparring is always dangerous. Not because they never half-ass anything and use actual lightsabers, oh no. It’s dangerous because after a half-hour of working up a sweat and chasing each other around someone is gonna get pinned to the nearest flat surface and devoured. 
• Rey initiates their first kiss. 
• The first time they have sex it’s a mess. It’s not “good” because they’re both scared out of their minds. Neither has been with another person before and they’d both heard all the horror stories. There’s a lot of crying and kissing and shushing and hushed declarations of love. 
• The Force Bond they share has led to a lot of very awkward situations but it’s also led to some very… interesting applications of The Force. (None of which the old Jedi would approve of at all.) 
• His pet name for her is “sweetheart”. Rey isn’t the pet name type, really, unless “quit hogging the bed you overgrown doof” counts. 
• The first big fight they got into (that was actually a fight like couples have and not war related) resulted in the leveling of a Sith temple, hoarse voices all around, and Ben’s three-night exile to the Falcon. 
• It took a lot of time for Ben to not be a little grossed out by the way Rey inhales food. He kept having to remind himself where she grew up and that she’d gotten used to eating before anyone could take it from her but it was one of the few things he absolutely did not find endearing about her.
• Rey actually feels pretty bad about the scar she left on his face. He’s endless amused by this fact and will of course tell anyone who asks. He keeps trying to tell her she should use it to her advantage as it cements her places as the most feared force user in the galaxy, but she still feels bad about it. 
• They get married on Naboo, because of course they do.
