I think the first thing to nail with a Micah x reader fic is the tone. 'Arcane' is so visually dense and emotionally raw, you can't just drop a generic reader into that world. The setting should feel oppressive and beautiful at the same time, all rust and neon. When writing Micah, remember he's not just sad; he's sharp, observant, and carries a specific kind of exhaustion from surviving. A scene where he's fixing something and the reader just sits in silence with him can say more than a page of dialogue. His trust is earned through shared quiet, not grand gestures. I've seen fics get his voice wrong by making him overly poetic or whiny. He's practical, even in his pain. The reader character needs their own practical skill to match—maybe they're a fellow mechanic, or a messenger who knows the lanes. That creates a basis for interaction that feels true to the undercity, where every relationship is also a transaction for survival. The romance, when it happens, should feel like a leak in a pipe, something gradual and unavoidable, not a sudden downpour.
Also, fight or action scenes with him are tricky. He's not a flashy fighter; he's clever and uses his environment. A chase through the Promenade level should involve him knowing shortcuts the reader doesn't, forcing a reliance that builds tension. The physical closeness in a hiding spot afterward is a classic beat, but it works because the adrenaline is real. Just don't rush the moment where he finally lets his guard down. It should cost him something.
