sans au erp romance

I'm wanting to use a oc for this erp.

I want to do a oc x character erp by now.

I don't mind if it's bxb or bxg

but anyways my idea was that someone from our world ended up by the multiverse inside of a place,or au,idk really.

as for what au we might roleplay in we can decide that if you want to.

I have some extra options ideas for the erp:

1: the character (oc) is a skeletal snake being,they were cold and get saved by the other or meet with the other.

2:the oc is an different kind of demon,an skeletal incubus/succubus,a beast that is trying to contain their own lustful desires away while they are slowly falling in love with the other being.

but as for the aus that I know?:

underswap

underfell

reborntale

rebornswap

rebornfell 

mythcaltale

underlust

and some multiverse stuff.
