Hi! How are you doing? I hope you're treating yourself well these days. All I wanted to say is that I love your writing! It's so neat and detailed<3
Hi, thank you for this <3 I'm not doing so great tbh, I lost a pet very recently and am currently scrambling to get moved out of my apt while fighting with my university for internship approval.... I'm so tired lol

please and thank you!!!
Hello! Thanks for your patience on this one. I was going to answer it sooner but really waffled between the final picks for a while. Enjoy!
Your matchup is……………………….
NAVIA !!
In the court of Fontaine, the Spina di Rosula organization is well-known for their service to their nation. Its leader is a shining example of both a well-cultured Fontaine lady and a duty-bound servant of the people, cutting no corners in her endeavors to bring relief and aid to those in need. In her personal life, too, she supports those she cares for, through words of comfort and handmade baked goods wrapped lovingly as parting gifts.
These are, as of late, not made by her lonesome. Her partner and friend can be identified less by her ever-fluctuating choice of clothing - which invariably ranges from the adorable and refined to the types of fashion worn in the depths of the Fortress of Meropide - and more by her presence. This is to say: if Navia is ever found to be talking about, carrying on her person, or handing out macarons, you can be sure that her partner has had a hand in baking them recently.
To Navia, gifts and acts of service speak volumes; and the time she and her partner spend baking for one another is superseded in worth only by the time the two of them spend happily at each other’s sides, wonderful moments full of laughter and promises.
Fun details:
You and Navia, of course, are bakers. Well-known in Fontaine by the local folks, too, for giving away your wonderful homemade goods! Naturally, Navia heard rumors of a Fontainian lady who’d both earned the people’s trust and also was a stellar baker - and she just had to meet someone who was so like-minded! (It’s safe to say you got along swimmingly right away.)
You’ll generate quite a lot of Crystallize reactions together in combat. Of course, neither of you is prone to getting yourselves into those types of sticky situations to begin with - you’re both too clever for that - but when push comes to shove, your sharp ripostes will move very smoothly with her powerful claymore attacks. You make a very striking duo, too, dressed to the nines as you always are.
Speaking of fashion - oh, you two have the greatest of times leading (and, often, creating) new trends in Fontaine! Chiori herself has fashioned each of you a weekly wardrobe. Finding ways to blend soft, girly looks with rougher skater and Meropide ones is a challenge you both tackle together - shopping, try-ons, alterations - it’s a tag-team effort. It’s fun to match sometimes, but you both also do enjoy when the sight of you two standing together is quite contrasted, too! Navia always takes your fashion advice to heart, and expect hers to also be sound if you should ask for it.
Surprisingly, it took a bit of time for you two to move forward beyond friendship. This is almost entirely on Navia’s side, because of her hesitancy to lose someone dear to her yet again so soon after losing her close companions. But it is too hard to resist the spark between you two, and your steadfastly positive attitude will only lure her in more.
She will completely understand your feelings about bugs, but she will be the braver of you two and handle them, carefully scooping the stray critter up and putting it safely outside. As for friendlier animals, you’ll both spend a good amount of time petting and feeding the dogs and cats that live in and around Poisson. It’s cute to see them recognize you two and come bounding over to greet you! Navia will love seeing the expression on your face whenever you spot a cute animal while you’re out and about.
Navia finds it impossible to say no to you for most things! She will express her affection towards you in a myriad of ways, but indulging in the things you suggest is definitely more than a tendency. Shopping? Let’s pick a time and day together! A new recipe? Sounds delicious - she’ll procure the ingredients! Dye her umbrella a darker color? Um, that one might not fly - but in general, you’re not going to find yourself getting too irritated by conflicts.
On the flipside, she will not indulge you in too-reckless behavior. This might lead to some friction in your relationship, especially if you try to prove a point or deliberately do something dangerous just to see if it actually is. After all, for all that she adores you, Navia does have the Spina to look after, so she cannot afford the luxury of jumping off that cliff alongside you. You’ll both have to compromise somewhat to make these types of conflicts work.
You are both very positive individuals. It’s part of what made you two click to begin with! A shared outlook on the future and what it might look like eventually brought you two together. Navia treasures each and every moment that you two spend by each other’s sides. Whether it’s tossing flour back and forth after a baking mishap, or covering each other’s weak spots during a difficult battle, or just sitting together enjoying desserts on quiet afternoon, looking out at the beautiful stretch of land just outside Poisson where it meets with the shimmering ocean… Each of these is a memory she holds deep in her heart. She has many visions for a future Fontaine that is just, safe, and stable, it’s true - but now, those visions are not of her standing alone. She has someone there beside her. (She hopes it will remain that way for a long, long time - as long as you allow.)
--I hope you enjoy your matchup! I also considered Kaveh and Dehya for you, but I thought the fashion and the baking were too much to pass up on!
i apologize for the delay on matchups. i received sad news this week so i am grieving. i have free time tomorrow and honestly need the distraction so i will begin publishing asks then.
please feel free to remind me via inbox if i don't post a matchup response within the next 24 hours - i have the first one nearly finished.
feeling really awful about the world right now SO!! To bring some joy back to it, I'll be opening up genshin impact and mystic messenger matchups! They will remain open for 48 hours. 💌💌💌
Here are two examples of matchups I've done in the past: Genshin | Mysme
Hello! I was wondering if i could have a genshin match up?
Base info (sexuality, pronouns, preferences):
Straight
She/her
I have no age preferences
Likes & dislikes:
I like doing my own nails (like gel x), staying organized, painting, shopping, skiing/ice skating. I like people who can take a joke, or are easily forgiving, I usually make harsh jokes or say things that could be considered mean, however this doesn’t mean i don’t expect people/want people to just take it, id also like a person i could debate with, or banter with! I like people who are complacent in me decorating them, ex: doing their makeup, dressing them up in cute things, doing their nails, and esc. I like more of a 50/50 relationship, where both partners put around the same amount of effort and respect in the emotional aspect, and i like paying for my partner/loved ones things.
I dislike people who are unhygienic, and I honestly cant stand it when people are disrespectful to their mom, or women just in general unprovoked. i dislike prejudice, I think people who are overly apathetic are abit strange,
Personality:
Personality wise, my friends would describe me as protective, argumentative sometimes (but i just like debating), and really loyal. Im not scared to get into a fight/physical fight for my family or friends, i love joking around with my friends and taking care of them, and i like teaching them new things or expressing my opinion on things.
Im more of a ‘everyone deserves respect’, and its their choice if they later loose it and i mostly disagree with people who think respect is earned. I would say im more emotional than rational because i can be rash at times, i care alot about my appearance, and i try my best to look presentable.
vision:
if i had to guess, i would think either pyro or dendro. I would consider myself really passionate about things that i like, and i love learning new things/studying
Flaw/ embarrassing moment:
Sometimes I find myself in situations with sexual undertones without realizing it 😓 i wont get into depth with it but it happens on the regular, i usually find out abt it when i go to sleep or when i shower. i get angry/snappy when its cold/hot out or when im hungry
Additional info:
Im 5’1, with mid-short brown length hair, i wear glasses but i usually just stick to contacts.
Thank you so much! Please remember to drink some water :),
Hi!!! This was one of the first times I've had a name come immediately to me! Enjoy!
Your matchup is........................................
KAEYA ALBERICH !!
There is a very interesting rumor that is making its rounds inside the City of Mondstadt's tall walls. The busy townspeople whisper in broad daylight about the Cavalry Captain's latest outing with his good friend, and they wonder whether he is starting to see her in a new romantic light. They offer evidence for their various speculations, ranging from gifts given to lingering touches to stolen, longing gazes seen by onlookers at the taverns in the evening. But they all agree on one fact: the Cavalry Captain is thoroughly smitten.
This is quite humorous indeed when the grand, romantic rumor is finally brought to your attention by a well-meaning friend. After all, the rumor is quite out-of-date: you've been Kaeya Alberich's girlfriend for a good, long while now! When you share the news with him, he'll have a crooked smile in response to it.
"If it's only speculation by now," he says, "I'll have to try much harder to make it obvious to them, won't I?"
Fun details:
The ferocity with which you defend your loved ones is undeniable in every way. Your Pyro vision is proof of that. It's very reliable, and applying Melt to opponents when Kaeya fights alongside you is just a bonus. Your moveset is sure to match his in style!
Speaking of style, Kaeya will happily take some pointers from you, letting you style his hair or paint his nails in a new color or pick his outfit for a day out on the town. When he's working, it isn't uncommon to find something or other you've left with (or done to) him on his person. (That's not to say he compromises his own style, of course, but it's a reflection of his delight with the care you put into those small details.)
Don't think for a moment that Kaeya won't give as good as he gets when it comes to banter - he can and will be sassy right back to you! He can laugh a good-humored joke off, too, and he typically doesn't take personal offense to jabs at his expense. (Just avoid family issues in the early phases of your relationship; those might earn you his ire for a bit if you risk it.)
As a respected gentleman in and around Mondatadt, Kaeya will never put you into a compromising position, and nor will he stand by and let you find yourself in one unawares. If someone makes a comment or suggestion while he's present, he will call it out (or at least call it to your attention) - how you deal with it afterwards is entirely your choice, but he'll back you up regardless.
You and Kaeya will most likely have small conflicts, when they do occur. You might argue over who's to cover the tab at Good Hunter, or whether the gift-giving has gone a little overboard from one of you recently. Each disagreement is a learning experience rather than a rift in your relationship, and you'll learn more about each other's boundaries, likes and dislikes from these discussions.
That's not to say you don't have disagreements on a larger scale. You fall into debates often, arguing over policies or city regulations or other potentially heated topics; but these, too, are not to be taken personally by either party. Instead, these are moments to push each other's viewpoints to the limits, to challenge ideas and knowledge, all in the hopes to grow as people. (These debates are especially popular in the evenings, when tavern-goers will - subtly, but not escaping your attention - place bets on which of you will be going home victorious tonight.)
Kaeya can pinpoint the exact moment he knew he was falling for you. It was a snowy day in Mondstadt, with the wind blowing cold and sharp; your cheeks were pink from the chill as you laughed, skiing across Cider Lake without a care in the world. In that moment, he desperately wanted to freeze all of time to preserve the sound of your voice, to keep the joy in your eyes from ever fading. It was a shocking revelation, but he had no time to process it, because then your eyes met his, and naturally, he made a right fool of himself by falling head over heels on the ice in his suddenly-flustered state. (And once you get together and find out about this, you will never, ever let him live it down.)
Your fierce loyalty to your loved ones is something Kaeya both respects and finds himself conflicted over - not because of you, but just because of his own contentious family history. You'll have to do a lot of emotional legwork to get him to open up about it, but in the meanwhile, he will happily let you share your own troubles and worries with him. He will not let his own difficulties cloud his judgement, and his advice is always fair and sound.
You will often meet him outside of the Knights of Favonius Headquarters, and he'll always be grateful when you treat him to a meal. (Expect him to return the favor as soon as he can.) This becomes so much of a routine that Jean, Lisa, and even Klee will tease him about it - and it's possibly the only thing that will never fail to fluster him a bit. Nevertheless, he looks forward to these meetups.
What Kaeya Alberich admires the most about you is your unwavering loyalty to your family and friends. The lengths to which you will go to defend them are nothing short of heroic. In his eyes, there are few things worth admiring more - but there are, admittedly, a few: the way your eyes light up when you laugh, how lovely your smile is when you win a debate, how fiercely you show your affection for him - all of these things leave absolutely no room for doubt about how deeply he loves you.
--I was also very close to choosing Ayato for you - he would also be a very good match, I think, though I figured the political constraints for jokes and bluntness might not be the best fit. Kaeya's name popped up first in my head as I was reading through, though. Anyway, I hope you like this!
I'm heading off to bed now. I have the next matchup completed, I just have to finish the matching visual and publish it. Hang tight, it'll be out before the inbox closes, I promise!
Matchups are still open! It's possible I may lose power tonight/tomorrow, so I will honor any additional requests received in the event I cannot close my inbox on schedule.
Hi! I'd like to request for a genshin impact matchup please. ^^
Pronouns: they/them
Sexuality: Idk but I prefer men
Age preference: No minors
MBTI: INFP
Enneagram: 4w5 sp/sx
Zodiac big 6: Cancer sun and moon, Pisces rising, Cancer mercury, Gemini venus, Leo mars
Moral alignment: True neutral (leaning slightly towards lawful evil)
Personality: Introspective and rational, terrified of conflict. I daydream a lot and tend to space out when I’m not talking to someone. I’m a true introvert, but I love to talk to certain people and about things I find interesting, like my fixations or a fun hypothetical situation. I observe people more than I want to interact with them. I'm also good at reading people (to the point where my brother thinks I can read people's minds). Purple represents me best as a colour.
I value my authenticity, creativity and emotional intelligence (I can’t say I’m really empathetic, but I listen to people when they need me to and I try to be there for them). But I am quite sensitive and emotional. I tend to remember events in which I was hurt easily. My friend would describe me as a jaded Disney princess because I daydream a lot and used to be idealistic as a kid but now I'm more of a realist/pessimist. They also say that I can be blunt most of the time.
I'm the eldest sibling but didn't grow up to be anything close to a mom friend. I was scolded a lot growing up for not being good enough of an eldest sibling, so I play the role of an observer when around my friend group, not going out of my way to help them if they make any mistakes (honestly I don't like friend groups or feel that close to them anyway). I prefer one-on-one interactions.
Also, according to this personality classification system, I am a mint (I agree, even the sadistic part). https://2-lines-and-a-circle.tumblr.com/post/692988945418633216/in-depth-description-on-flavors-mint
Hobbies: Reading, looking for fanfiction with amazing writing styles (descriptions, vibes, the closer it reads like poetry, the better), writing (fanfiction for now, but I plan to become a professional writer in the future e.g. movies, tv shows, manga), listening to music, psychoanalyzing people, analyzing fictional characters, watching horror movie summaries and anime/movie reaction videos
Likes: POETRY (I follow the web weave tag here and my favourite poet might just be Richard Siken), tofu (my favourite food), chocolate, books (the genres I tend to read are thrillers, fantasy or sci-fi), anime (mostly shounen, but I've watched some movies as well), manga, analyzing characters with many layers to them, personality typology (the closest thing I've had to a hyperfixation. my all-time favourite is enneagram, but I’ve had astrology and MBTI phases), action or comedy movies, visiting cafes, looking at sunrises and sunsets, watching storms (LIGHTNING), crochet flowers and plushies (I don’t crochet, I just buy them), phone charms, the colour purple, window shopping, video essays (marketing - celebrities, not companies, somewhat deep topics like love and philosophy, literature and film analysis - especially themes of horror movies, despite me being too chicken to actually watch the moves)
Dislikes: Exercising, studying for subjects I'm not interested in, being forced to interact with people, having a sudden change in plans that I don't like, many foods like anything spicy or really bitter (I am a very picky eater), bugs (beetles, bees, spiders. I don’t kill them and are fine with them as long as they’re a distance away from me. I get scared when they move about tho), noisy environments, construction noises, small talk (I actually don’t mind talking to people, I just need them to talk about something interesting or at least something they’re passionate about)
Type: Someone intellectual that I can talk with. I wouldn't be able to stand a SO that often cuts me off when I'm trying to talk (especially when I would never do that to them), or someone that's only interested in talking about themselves.
Miscellaneous:
Many people have called me pretty. Also complimented my handwriting, they say it's so neat it looks like computer print.
I don't like when people touch me most of the time. I like to touch them on my own terms. Like a cat.
Tend to get lost in new places. :’)
Thank you for your hard work!
Hello! Thank you for sharing so much detail, this made it both incredibly easy to narrow down to a handful of characters and also painfully difficult to select the final one. I hope you enjoy your matchup!
Your matchup is..................................................
NEUVILLETTE !!
There are those who would easily, and without much thought, misconstrue impartiality for disinterest. Rather, this is the most fundamental tenet of observation: to glean from afar the veracity of what can and cannot be seen with one's own eyes. For it is only once this is done that true judgement can be pursued.
For those who truly observe, the relationship between the Iudex of Fontaine and their partner is one that cannot be told in words alone; actions, rationality, and substance dictate their relationship. This is not to say it is devoid of emotions - far from it, in fact - but it highlights the manner in which they conduct themselves around each other. They are, in this respect, their most honest selves when together.
And, to Neuvillette, what greater sense of justice is there than in upholding truth? Perhaps this is what draws him to you initially - a shared sense of reservations in a room full of acting, or else the eager way you both fall into quiet contemplation - but, undeniably, what strengthens your bond is the undercurrent of authenticity in every interaction you share.
Fun details:
Considering your association with purple, is it any wonder you received an Electro vision? Your attacks, like your tendencies, are seemingly reserved - simple movements that don't stray into wildly flashy territory - but they pack quite a punch! You and Neuvillette will rarely be involved in battle together, but if you are, your opponents are in for a world of pain!
This man (dragon? judge? he is a man of many forms) will absolutely understand your introversion, and will respect it at all times. He will always listen intently and curiously to whatever it is you have to say, letting you finish first before bringing forward any additional ideas of his own. Like you, he enjoys his personal space, and there will be many times wherein you both sit comfortably apart without touching - there are other ways of communicating besides touch, after all, and if either of you does want physical contact, it's simply a matter of expressing the desire and the other allowing it.
He will feel honored when you are comfortable enough with him to begin sharing about your hyperfixations and your interests. He will always make time to listen to you, even if it means he has more work to attend to later for doing so. He will find himself quite invested in some of these, too, after a while - he'll ask follow-up questions and, in the case where you might have your own questions or be perplexed by something, will take time to conduct his own investigations or research into the subject in the hopes of bringing you some satisfying answers.
Neuvillette is also a very sensitive person. He is not outwardly emotional, but what he does feel, he feels very deeply. This will be a matter you two can discuss one-on-one, but it will feel very intimate to both of you because of how vulnerable it makes you seem. Together, you can talk about the things that have hurt you in the past and how to best communicate with one another to avoid accidentally or inadvertently contributing to those painful memories. This is not one-sided, either - he has quite a lot to work through himself! Having another perspective might prove to be rather eye-opening for him.
Speaking of discussions - he will be fascinated by your interest in typologies. How applicable are they in day-to-day life? In anecdotal experiences? Have they been used in courts of law outside of Fontaine, and if so, to what level of success? He will ask many questions about them, primarily out of the desire to understand how the human mind organizes personality. This will surely be a perfect segue for you to convince him to take a myriad of different typology tests himself!!
A particularly fun pastime of you both will be people-watching, especially at teatime breaks. Whether you're comfortably cozy inside your place looking out the window at the street, sitting outside at a quieter cafe, or looking down from a balcony off the Palais Mermonia, you two will find it quite interesting to observe others going about their day. Neuvillette will never not be flabbergasted at how good you are at identifying people's emotions, and your explanations (about a tell in their movements, or some bend in their brows, or a flash of something in their eyes) will always take him by surprise. Eventually, he will begin to pick up on some of these things, but the overall nuance will still elude him. (If you want to, this is always going to be a great topic to tease him about.)
Your interest in written words will be a shared one. He attends to documents and records on a daily basis, so the preservation of such things is not new to him; however, the art of poetry and stringing words together to elicit particular responses will be something that intrigues him greatly. You can share your favorite works with him, and he will actually read them. Entirely, and without judgement! (Just expect him to bring back notes like some Akademiya student afterwards - he will have much to discuss with you, from syntax to tone to subject matter.)
The most common cause of contention between the two of you are your differing morals; Neuvillette is not devoid of sympathy, but his devotion to the moral code of Fontaine is second to none. Compared to your own neutral leanings, he is very much a stick-in-the-mud. But repeated discussion and debate will broaden his understanding of how varied human morality can be, and to be fair, his view of legality is separate from it. Those will be fun conversations - once you're both over the (admittedly, quite daunting) hurdle of recognizing that disagreement does not equal true conflict.
M. Neuvillette is, despite the assumptions of the people of Fontaine, a very warm and gentle individual. He attends to his obligations with a sense of duty-bound rigidity. But outside of these, his gentle nature can be observed - in the way his eyes soften as they meet yours across a dark theater, in the books of poetry he consumes to better understand you, in the comfortable silences that stretch between you two as the evening falls; and in the way he learns just how deeply his devotion can run.
--I was so close to giving you Baizhu or Diluc, too, agh! It was a tough choice! I know next to nothing about astrology and only the basics of personality typology as they're taught in psychology coursework, so it is my hope that this relationship could swim on vibes and similar views alone, lol!

@imjustabeanie thank you so much for reaching out about this matchup exchange, I've had a blast doing this again!!
Your matchup is.................................
ALHAITHAM !!
Among all of those associated with the Akademiya, none are considered as calculatingly cold as the former Acting Grand Sage and his girlfriend. Students and Sages alike tend to tread warily around them both, lest they earn their sharp ire and harsh denouncements.
Of course, among those who consider them their friends, such worries are unreasonable (though not, admittedly, entirely unfounded). If a person is on the receiving end of their criticism, it is most certainly because it is deserved. Nor is the matter of how that criticism is taken either of their problems to deal with. After all, to both Alhaitham and his partner, brutal honesty is not "brutal" - it simply is.
Fun details:
The two of you definitely met because of an overlapping interest in a personal research topic. The fact that it continued to overlap again and again - well. Whether it was intentional or not, neither of you will admit to it one way or another, even under Cyno's line of questioning. (This is partly out of spite, but mostly just to see your friend group's frustration upon failing to get a straight answer out of you.)
Both of you are misunderstood by the majority of Sumeru. Alhaitham is perfectly fine with this. You tend to simply not notice. Whenever Kaveh or another friend brings it to your attention, you both logically remind them that the opinions of your friends matter more than those of complete strangers.
You and Alhaitham will be the death of Kaveh, by the way. There's a distinct lack of care for the fallout of your barbed words - those egos of yours, really! - that he tasks himself with trying to clean up for you afterwards. Maybe one day he'll learn to let it be - in the meantime, you and Alhaitham can amuse yourselves with the many shades of red his face turns.
You both HIGHLY value honesty. Admittedly, Alhaitham acknowledges that truth sometimes "means nothing at all" - but between the two of you, it is one of the greatest tenets of your relationship. It's what makes it truly work so well, your openness to feedback and complaints as they crop up.
Not to say that you don't have your differences. You indulge your friend's bad ideas often enough that Alhaitham is not unused to hearing about the consequences of your own actions, and being entirely unsympathetic to any resulting plight. Meanwhile, you think Alhaitham could stand to live a little more - there is only so much to be learned through words on a page, after all, much as you both enjoy reading. But you respect one another's choices.
You are both not the types to bring your baggage out to air in public. Or private, either, really. Whatever skeletons you each may have in your closets, neither of you will ever try to pry the other's open - that is to say, you'll let them come to you with those things if and when they're ready to share that burden.
Alhaitham can definitely keep pace with your racing mind, managing to follow your leaps of logic and thoughts without you having to explain them often. The two of you value sharing time with one another - most evenings are spent in one another's space, whether it's cuddling as you discuss your days and engage in lively debates or silently sitting on the couch, nudging each other with your feet as you read into the night. Learning for learning's sake is a shared love of yours.
Alhaitham is not the type to be overly physically affectionate, but he shows his feelings through actions and gifts. Dinner, brought home after a late work night; a new book over your shared interest topic, with a brief handwritten note slipped inside the front cover; a new piece of clothing to replace the one mucked up recently by a scuffle with some fungi, in the exact same shade and size as the old one - he gives you things he considers both valuable and practical. (Unfortunately, anything "aesthetic" he gets you will probably be... erm... eclectic. 50/50 whether it'll actually match YOUR aesthetics.)
He likewise values your thoughtful gifts to him. You'll find them proudly on display and scattered around the house, or carefully tucked along the bookshelves near the things he inherited from his grandmother. (The rest will fit in his pockets, somehow, or be incorporated into his daily routine.)
Maybe you're both a bit too harsh, in the eyes of some. Those opinions hold little stock in the grand scheme of things. Certainly, to your boyfriend, they have little meaning to them. Simple pleasures - having fun among friends; slipping a new book into place on your desk and watching the way your eyes light up at the sight of it; opening a present you give him to discover it's just what he's been needing this week; falling asleep and opening his eyes to the sight of you, warm and content beside him - these are the things worth time, worth effort, worth keeping. Those shared, stolen moments between the two of you are the most meaningful of all.
It was honestly a toss-up between Childe and Alhaitham; Childe would match your chaotic energy and enthusiasm for life more than Alhaitham would ever be able to, but he's also deceived people canonically more than Alhaitham has, too. In the end, they would both be excellent matches with you, but I hope you enjoyed this one!
