I'm Mousi and I've been around since HP fandom in like 2003 (god I'm so old). I've been mainly in Johnny's Entertainment fandom for a long while now, but I love shounen and sports anime, so once in a while something sticks.
My AO3 is mousapelli but the easiest place to search through my insane amount of fic is on Kira-Kira.net, my website. The newer stuff will be on Ao3, though, because I'm not the best at updating, and for anime fandoms it's a more worthwhile place to post.
I'm really easy, honestly. If you write something that you enjoy, the odds are that I'll like it too. If you need more guidance, I tend to write the kind of thing that I enjoy reading so you can read through some of the stuff on my archive. In general I lean towards slice-of-life, banter, group fic, that kind of thing.
Friends/teammates hanging around, group setting, banter and teasing, boys just hanging around and doing stupid stuff together, hijinks. I love group setting, so friends at school, or rinkmates, teammates or university friends, that kind of thing. I like all kinds of relationship fic like confessing or getting together or established or moving to next level, casual hook up turns into something else, pretty much anything is fine. Gen is okay too? If it's got a good hook to it, like about character development or people growing together, or something like that.
I actually really like horror or scary stories? Like ghost or supernatural type, not gory. But unless you have a GENIUS idea I'm not sure I'd want to see one with any of the fandoms/pairings I signed up for.
Neutral (wouldn't ask for it directly but I don't mind if it appears)
I don't hate AUs but I prefer fic that's close to canon (aging up is all right, though). Somehow this year ABO became a thing I'm totally fine with, up to and including mpreg if there's a decent explanation for it. I sort of gently don't mind sex/relationship that have a non-human partner (Dark Shadow/whoever in BNHA for example, or the AU where Kirishima is the dragon/Bakugou). In-canon type violence or sports injury don't bother me at all.
I'm not intensely kinky and I don't read a lot of stuff with toys, serious domination, fetish things, etc. I can take tense or sad fic so long as it's going to come out all right in the end, so unfixable things like character death or major injury aren't any good (although see above how good horror/scary fic as an exception). I really like the characters just as they are 95% of the time, so you're better off avoiding stuff like gender swaps.
You do you. I love porn, sure, but if you end up with slow burn friends to lovers and all I get is some kissing, I can live with that for the sake of good build-up and/or plot.
Honestly I feel like I already said what I had to say about these fandoms on the form, but here are some more thoughts if you want them:
I am totally into Suga/Asahi, Hinata/Kageyama, Kuroo/Tsukki, Ukai/Takeda, and also think Bokuto is amazing. I love everybody on Karasuno being friends and helping each other and working out, and training camp or going to nationals or studying together. I really like the future idea of Yamaguchi being captain, and of Kuroo, Daichi, Oikawa, and Bokuto all being together at university in Tokyo together, and I also have a weird interest in Bokuto/Oikawa in that scenario because I think they'd be so into how the other one will also practice until they die. GYM 3!! I like the friends who have been friends for a long time (Tsukki and Yamaguchi) just as much as the pairs who are learning to be friends now (Hinata and Kageyama, Kenma and Lev). and I ADORE sassy senpai (Suga, Kuroo, Bokuto) making their kouhai's life troublesome.
This is also a fandom where i'd really go in for OT3 or OT4, for instance any combination of Kuroo/Bokuto/Akaashi/Tsukki, or any combination of Karasuno first years (including Yachi), or any combination of Gym 3.
Yuri on Ice
I'm super into the Yuri/Otabek (i don't have a weirdness about their ages, but if you need to age them up for you, that's fine). There's just a lot of ground to cover there with living and different countries and training and Yuri's growth spurt about to happen. I love language/cultural differences in general in this show. I love how Victor/Yuuri are something in between friends and mentors to Yuri and I think it'd be interesting to explore how that relationship changes as Yuri gets older and the age gap narrows. For Victor/Yuuri, both fic set in the spaces of the series and fic about the next year in St. Petersburg are both good. Trying to figure out how they're going to live together, where they're going to live, just working out logistics. You could really write some amazingly hot, established relationship sex for these two.
When I watched this, I thought a lot about how Haru and Rin both needed their teams really badly, and how they would have probably been better off as people if Rin hadn't gone away for so long, even if it made them better swimmers (they can make up for it now, though). Also that Rin ended up super happy at Samezuka and any kind of dorm shenanigans or team bonding would make me really happy. For Nagisa/Rei I think you could write really adorable getting together fic where either Rei is a basketcase trying to confess (meanwhile nagisa already knows) or else he's completely oblivious while Nagisa is using all his wiles to get them together. What do they even do their senior year with the others having graduated? Rin and Haru trying to figure out each other at the same time as they deal with university and a professional career and olympics, or else how they've already figured out how to work together even while Haru struggles to cope with change while Rin is always running towards it. Being best friends. Being angry with each other and having other best friends to turn to.
I'm due a rewatch of this and I'm only caught up as far as the anime even when I was watching, but honestly I don't care about spoilers if you're further. The only thing I'd be super into here is Mihashi/Abe, either them fumbling to get together and Abe struggling to get through to Mihashi, or them as established and trying to work through whatever new parts of their relationship or dealing with losses or setbacks together. Or heck, flip the whole thing backwards and have Mihashi trying to get his feelings across to Abe, or their teammates trying to hook them up (even if they maybe are together already and nobody else knows yet).
Thank you again for writing for me! I hope you have a good time!
