Hello! You are the first to ask a question!! Yes I can, you could ask for any fandom fan fics and I'll tell you if I can write for that but here's some stuff I'm familiar with and can write for (not guaranteed I know a lot about them):

-MCU (marvel cinematic universe) -My hero academia -Miraculous ladybug -Haikyu!! -Beastars -Saiki K -Maid-sama -Detroit: become human

haha I haven't read any of his yet, but I would love to write one about him eventually. But as you can see, I'm already only able to update this once a week. Adding another story at the same time would be crazy and neither would end up getting done. So I'm going to add that to the ever-growing list of fanfiction I have to get around to writing. 

I've already promised an Iker Casillas one next and then we'll see where I go from there
