tbh hvswp/fs ships have kinda been free for all cos the fandom is pretty small so ppl just kinda ship and do whatever they want XD I think the obv popular ones are the heavily implied canon ones like stelsa/tyzias (stelzias,lawsbians), galekh/tagora (galora), elwurd/bronya (bronwurd), folykl/kuprum (folykup), konyyl/azdaja (kondaja)... idk if i'm forgetting any other canon ones LOL

i rmmbr charun/cirava (vaporworm) (fan of this one tbh) used to be semi-popular back in 2018. There's a lot of crackship pairings for hvswp cos a lot of their interactions (as far as we've seen) have been pretty limited LMAO.

i have a crackship agenda for Elwurd/Lynera (lynwurd), Skylla/Ardata (skyllata), and Chixie/Remele (remixie) BUT NO ONE HAS OPENED THEIR EYES YET.......
