Looking for a free game to play a very specific character

the character i have in mind is a changeling who has multiple persoanlities. she does not work the exact way a changeling does but there are no mechanical changes to it or her classes. With having two personalities she also has two classes. though the classes can change to fit the group, the concept is that one of her personalities is a religious type trying to be a proper warrior woman, the other just likes to enjoy life. She will probably flirt with others and sleep with with one (not the Party unless they want to, but even then it is going to be quick with saying "We do our thing" and then it is over i don't want anything more than that others can do what they want for all i care, but this is what i want to play if you can handle this kind of character or are interested in her reply or message me so we can talk about what i have so far.
