I think modern au kylo and hux have high tech gaming computers but don’t know shit about gaming.
They desided to play minecraft together and they argue about where to build a house. Hux ends up making a house in a tree. Kylo makes a house surrounded by lava. They have wars and taking over villages. They make banners and ride houses. They just get so into the world they built but are laughing and just having a blast.
At night, they talk about there kingdoms well snuggling and kissing. They name there villagers. They think about having a kingdom contract and marry in game. It ends up being a emotional event.
