I've noticed a pattern where most writers start by amplifying their existing hostility from the game. It's always the snarky remarks at the tavern, the constant bickering during missions, that sort of thing. But honestly, a lot of those early fics feel like they're just rehashing canon dialogue with extra glares. The development kicks in when someone decides to ask why they're so hostile. That's when you get the good stuff—flashbacks to their shared past before Diluc left, maybe exploring a sense of betrayal Jean felt that's never addressed in-game. The shift from rivals to allies usually happens over a life-threatening crisis in Mondstadt, forcing them to rely on each other. After that, the tension changes; it becomes less about anger and more about this heavy, unspoken history. The best stories I've read don't rush into romance. They let the professional respect solidify first, the slow realization that they're two sides of the same coin, both sacrificing everything for the city. It makes any eventual softening feel earned.
Lately, I've seen more fics playing with the idea of Jean being the one to reach out, not Diluc. It's a refreshing twist on the usual 'broody guy thaws' trope. She'll extend an olive branch about coordinating Knight of Favonius and Dawn Winery resources, and he's so thrown by her directness that he can't just refuse. Their interactions become a series of strictly professional meetings that accidentally get personal. He lets a detail about his reconnaissance slip; she shares a frustration with the Acting Grand Master role she tells no one else. It's a quieter development, built on shared burdens rather than explosive drama.
