    Summary

    Kaeya never dreamed that a simple mission of taking out a Fatui base, could go so incredibly wrong.

    UPDATES: Mondays & Thursdays

    ((This is just a de-aged Kaeya story that I couldn't get out of my head so here we are.))

    Summary

    Birthdays are often celebrated in various ways such as a birthday cake or even a simple present from a friend or lover. Kaeya and Rosaria celebrate it differently due to their different views on life. Whether it'd be gifts or spending time together with friends and family, they'll say a birthday is just another passing day.

    Summary

    “Get out of here!” Diluc screams at him. “I don’t ever want to see your face again!”

    And so he does.

    Or,

    After his fight with Diluc, Kaeya escapes to Dragonspine and stays there, teaching himself to survive instead of returning to Mondstadt. It’s not too long until rumors of the signature snowy mountain of Mond being haunted begin cropping up, causing less and less people to travel through Dragonspine over the span of a few years.

    All the while, Jean worries over the disappearance of her friend and Diluc eventually returns to the nation only to discover that his ex-brother has long been missing. Not that Kaeya has any idea that any of this stuff is happening, being left clueless as to why everybody has vacated Dragonspine, even if he tells himself he enjoys the solitude.

    Summary

    Their agreement was pretty simple. It was to be a physical relationship, just mostly sex, no feelings, and nothing more.

    But at some point in time, the both of them will wonder where everything went wrong.

    Summary

    Diluc was too tired to be angry or to deal with the panic still simmering beneath his skin. It was too easy to fall back into his older sibling habits, soothing his little brother when he was in pain.
    Maybe just for tonight, Diluc could put a lock on betrayal and anger and just hold his little brother as he had wanted to for the last four years.
    “’Luc?” whispered Kaeya softly, head lolling against the hollow of Diluc’s neck. “Yeah, I’m here” Diluc hushed, pressing his forehead against Kaeya’s shoulder with an exhausted sigh. “It’s going to be okay, Kae. Just stay awake for a little while longer.”

    Or:
    Kaeya pushes his drinking habits too far and Diluc is there to pick up the pieces.

    Summary

    The Kaeya Birthday/Crepus Funeral Fic no one asked for

    Kaeya struggles under the weight of grief he feels no right to. Diluc faces the reality of three years apart.

    “As an Alberich, you must overcome your emotions,” a man whispered as he guided a stumbling boy in the dark. 

    “Us Raginvindrs are the teary sort I'm afraid,” another man laughed, patting a different teary-eyed boy with a laugh. 

    Kaeya closed his eyes against the memories, listening to the music start. So different yet similar in the end—neither of them were impervious to the dark call of the Abyss.

    Summary

    I tried to give this a decent summary but basically they're forcing Kaeya to stop drinking so he can actually get his mental health in check. It just so happens they're sending him to Dragonspine where Albedo is in charge of the recovery period. Kaeya is unsure if it's a greal deal or an utter nightmare.

    Summary

    The doors to the coffee shop suddenly slammed open, and a voice Kaeya recognized all too well boomed throughout the store.

    “Excuse me, peasants of this establishment. My name is Diluc Ragnvindr of the esteemed Ragnvindr family and I would like to purchase… Kaeya?” Diluc ceased his striding into the coffee shop. “What are you doing here?”

    Kaeya was standing behind the counter when he made eye contact with Diluc. “Diluc? Isn’t this a little cheap for you?”

    “I’m stopping by because I was here and needed coffee. Do you…work here or something?”

    OR

    Kaeya and Diluc haven’t seen eye to eye in a long time. When Diluc walks into a cafe while Kaeya’s working his shift, it rekindles a lot of the emotions he’s been trying to push down. Pair that with Rosaria moving into Kaeya’s apartment, who’s seemingly hell bent on getting the two brothers to make up, and Kaeya’s life is set to take a turn, hopefully for the better.

    A series of one part scenarios (or more) of each of the pairings you see above (we will hopefully try to get to them all)

    Not every pair is seen as romantic so please don't get mixed up with them, but the titles of each chapters should be clear enough

    Summary

    "I don't see you smoking very often, what's the occasion?" Rosaria asked, without looking at him.

    The captain did the same, keeping his gaze on the night sky without blinking. "Releasing tension. You?"

    "No reason."

    -

    Kaeya and his knights were on an expedition for a week, on the last day of work Kaeya overexploits his vision, which ends up almost destroying him. Diluc manages to arrive but his plans do not include helping him in a healthy way.

    Kaeya and Diluc talk, and somehow it all ends with Diluc pointing his sword at him.
