TBH super Offering / Little Witch / Corrupted Maiden feels.
IDK just gives me general Elotor feels but maybe Accidental Revolution? Or Dark One saving Elodie in the Corrupted Maiden AU from something?
Dark One Astor though like, having Elodie play dress up in front of him in all sorts of slinky outfits? >_> Nevermind a closet for her to change inside of, she can just do it right in front of him~
