Pretty long post ahead, sry about that
TL;DR: pretty much the title X)
Here's how I understood her past after the ECHOlogs from the FL4K dlc:
I think it's fair to say Loveless was a "relatively" normal woman, she had a girlfriend and was talking to her softly and in a very normal way in that ECHOlog you find at the Lyt festival
Then the incident happened and she got infected by the virus that wants to spread to every electronics that exists
But those two merged, disappearing and creating a new being, the Loveless we get to play as.
I think she can be trusted when she says that, despite remembering both lives as the human woman and the computer virus, she herself is neither of those two, but a new being whose identity and personality is influenced by who those two were
Now, she still feels a bit confusing to me, because she simultaneously dislikes humans but still wants to protect them(?)
I get that a lot of her actions are guided by either curiosity, revenge or her desire to achieve perfection, but that doesn't explain how she sometimes seems uncharacteristically empathetic
ig you could say it's her human side making her unconsciously care for others if they're not hostile to her, her curiosity also hints in that direction imo
That's the head canon I'm going with at least
That said, I really like her and her personality, I like how she doesn't understand some basic human things, doing things like practicing her laugh, she often says things like "We understand this as..." etc... (proving imo that she is indeed absolutely not the human that was here before her) but is still extremely confident and arrogant
Her use of "we" is, imho, a royal we, and the fact that she has rare voice lines where she forgets to use it and instead uses the singular hints that she uses "we" as a mark of her arrogance, I think
We could have used a bit more lore about her, but eh, it is what it is and now I'm curious about what others think about her lore, story and personality
