Eliza has significantly more implied snark, greater entropy, and a darker tone. They are also a god-tier poop-tooter. You seem more innocent and practically reserved, so far, which is amazing considering your proximity to them.
Neither of these are critiques, by the way; just early observations. I think Eliza is great, if a little beyond my ken at times. And you seem nice.
I can relate to the cynicism, and while I loathe to use the word "trauma" for my past negative experiences with others, (feeling that they are not significant enough to qualify as such for me), I do believe they have shaped me quite noticeably.
It's interesting, not being plural myself, I can still relate to having a distinct duality regarding certain things, my sexual inclinations being one of them.
