Fanfic requests?

  Would anyone be interested in me writing any fanfic requests? I've always wanted to write fanfic but I can never know what media to do because I'm dumb

Lists of medias Ik of

-Harry Potter, HxH, Tpn, Omori, DDLC, Kakegurui, Any NomNomNami game, Ghost and Pals, Vocaloid, Pjsekai, Mlp, A silent voice, Alice in borderland, All of us are dead, Stranger Things,  or your OC's!

(yes I put this in forums and in blogs I didn't know which one to put this in)
