I haven't read any kavetham/haikaveh fics yet but bgtea is like one of my favorite genshin writers and they have a couple fics of them you could check out, also they might come out with an isekai plot for them as well (shared it on twitter) and I'm just praying they do cause I'm gonna read that one for sure
thebetterbina is also pretty good and has some haikaveh fics!

I have an unhealthy love for kaveh x Alhaitham, so if you know any good fanfic, please let me know(￣∇￣")
I would also appreciate any other ships(not anything weird pls)
I have a personal favourite and that is "Brief, to Alhaitham's Grief" by anonymous on Ao3
