Welcome! As the name suggests, this is where I'll be sharing my Honkai Star: Rail x Reader work from my Tumblr (aventurineswife).
I'd love to hear your requests, so feel free to send them in! I hope you enjoy reading!
Warnings: Most of my fics are...
Summary: You and Aventurine are sharing a relaxed afternoon, and a playful argument about his so-called "inspirational mess" turns into teasing banter. When your frustration leads you to mutter in your native language, Aventurine—who’s secretly been learning it—seizes the chance to tease you in return. Caught between embarrassment and laughter, you realize he’s been one step ahead, and Aventurine is all too proud of himself for the surprise.

You’re both lounging around his suite on a lazy afternoon, a stack of paperwork untouched as the conversation somehow spirals into an easy back-and-forth about each other’s quirks. It’s all lighthearted and playful, but it doesn’t take long before you’re teasing him for his incredibly deliberate way of never quite cleaning up his cards and dice, always keeping them just a bit scattered, “for inspiration,” he claims.
“Inspiration, huh?” you say, raising an eyebrow. “Well, maybe my inspiration would be higher if I didn’t trip over your cards every time I’m here.”
Aventurine raises his hands in mock surrender. “I’m telling you, darling, you can’t rush art! It’s all about the atmosphere.”
“Atmosphere?” you scoff, switching to your native tongue as you get more animated. “More like a mess that you just want me to overlook!”
He smirks, feigning offense. “My ‘mess’ is a masterpiece—unlike someone’s habit of muttering incomprehensibly every time they don’t get their way,” he teases, with that knowing look in his eyes. He’s clearly waiting for you to switch languages again.
You roll your eyes, slipping into your native tongue almost instinctively. “Maybe if you weren’t so infuriatingly full of yourself, I wouldn’t have to mutter at all.”
Aventurine chuckles, his grin only widening. “Full of myself?” he repeats, pushing back just enough to keep the mood light. “Look who’s talking—every time you walk into this room, you practically take over.”
“Take over? Oh, please,” you huff, slipping deeper into your language as you mutter, “if anything, I’m saving this place from turning into a pigsty.”
He raises an eyebrow, clearly waiting for the right moment, and finally, you let slip a particularly choice phrase—a cuss word that, in your language, translates a little too directly to “fuck you.”
He seizes the opportunity, his face lighting up with a triumphant grin. “Oh? You’re offering for once?”
The world goes still. You blink at him in shock, the realization dawning as your mind scrambles. He understood you—completely. Your cheeks flush, and before you can help it, you’re sputtering in your native language, tripping over words and trying to make sense of how he even learned it.
Aventurine just stands there, that infuriatingly smug grin plastered across his face, arms crossed in satisfaction. “Surprised?” he drawls, clearly reveling in your stunned reaction. “Turns out you’re not the only one with hidden talents.”
You start freaking out, half-laughing, half-ranting in your language, swearing at him all over again. He just chuckles, standing back and drinking it all in, proud as ever for catching you off guard.
“Oh, please,” he says with a chuckle, “keep going—I’m starting to enjoy these rants.”
You cover your face, torn between embarrassment and laughter, and finally shake your head. “One day, I’m going to get you back for this.”
He leans closer, his voice low and challenging. “I’ll be waiting, darling.”
