What do you know about the idea of being fiction-hearted?

I like the term fiction-hearted. As far as I’m aware its a similar term to one that I came up with- fictionheir. Basically either are good terms for someone who has chosen to identify with a fictional character and take on elements of their persona. Its a good term for people who identify with a character or associate with them, but don’t think that they literally are/were that character.

Fictionkin: don’t chose their identity, experience involuntary feelings/memories, identify AS a character or FROM a fictional world

Fiction-hearted: chose their identity, do no experience memories, identify WITH a character or a fictional world
