why are they possessing him? how are they both doing it at the same time? how is he able to resist them both? what purpose is there for three beings to share one body? what is the conflict between the angel and demon? what would the person he meet up with be able to do as far as a resolution goes?
and from a writers place;
are we writing out 6 chars then? of the three who would get priority as the 'main' storyline? is this a religious story(since those are religious creatures)? would this be high fantasy or current-times with a fantastical element?
same still applies, i only play male and for the sake of avoiding concerning stereotypes and lack of general understanding i would really prefer my partner play male as well
only if it has a purpose, i do not do romance for romance's sake even in romantic-themed rps XD those tend to just flit around being coochie-coo then get dropped out of boredom, there needs to be more to it, something to make up the heft (like cake does with romance being the icing, you cannot have just a plate full of icing)
i think i should mention now i only do m/m mxm and m&m
