Imagiromantic is a subset of fictoromantic where one is exclusively or nearly exclusively romantically attracted to fictional characters whom they could never see because the type of media they're from doesn't include images. This includes novels, poems, and any other forms of literature/fictional media which revolve around something other than visual representation like pictures, comics, or drawings.
Examples would be being romantically attracted to a character from a novel or a podcast whose image is never shown.
