I’m an aspiring author and I heard about the Hannahaki disease and now I’m totally obsessed with it but when i looked it up it says its not public domain, but that its also doesnt have any known origins. Does anyone know if its still legal for me to write a story about the hanahaki disease? Also if I write one anyways what will happen? Will I get sued (cause I lowkey can’t afford that) or something? Is there also a way to still write one like if I credit the author or something? If anyone knows lmk :)
