So I'm too tired to come up with an actual theory right now, but here are some thoughts.
The mc has black hair. She never mentions having to dye it or anything. But conversely, something interesting about the actual princess we see in the flashback is that her brows are dark unlike the commander's so could she have been bleaching her hair.
Purple eyes are a trait of the Logos empire, as duke Gray kept saying that one time. The eye shape of the princess and Lucien isn't too far apart though.
If the princess and Lucien are the same person, then that raises the question of how each life works, because I doubt Lucien lost her memories. Logically, it doesn't yet make sense for God to confiscate any of her memories unless she maybe did something distasteful.

What I really like about this is the plot and mc's attitude. The worldbuilding is so well done and the politics of the situation are interesting. And following the ml gives us a lot of insight into the military situation. The best part is how capable ml is, he really does play the role of commander.
And the situation really does feel like the mc has no choice and had no way out of the situation. Nothing felt like an obvious trap and the mc's reactions feel so realistic
Also, our mc really feels like a detached being that exists outside of humanity but has also been forced to join them. The lack of emotions really fits the idea that she has lived 8 additional lives but I like her little outbursts of emotion. Like her punching Count Gray. Speaking of count gray, I love her little reflection on how Count Gray doesn't regard them as human and I want to see more of her reflecting on human nature.

Nah....there were pretty obvious traps mc could of avoided.
She, ultimately, is the one who put the children in that position. She's lived 7 lives. You'd think she'd have learned, but instead of convincing the children of how bad the idea was- CHILDREN- and putting her foot down, she got swayed by their delusions and had the gal to be surprised. Such a big diamond was bound to have a lot of people after it, and they thought a group of amateur children could? Don't be ridiculous.
I actually quite like this story, but it's also true the mc is way too attached and gullible (dare I say stupid?), traits that don't really work well together when you're an inmortal being.
Just my two cents.

Honestly you're probably right about that because I came back to this after a couple chapters updated and assumed that it was a group of adults not teens and kids oops
But I still think it feels a bit like she's playing around when she's doing things. I'm probably looking too deep into what might just be stupidity and attachment issues but I kinda imagine her like someone playing a story based game where your attached to the game and you kinda want to help out the characters and hate the bad guys but you still wouldn't lose much if you failed so you don't act too seriously and kind of play around at times (like in the beginning when she has the verbal fight with that one rich prostitution lady or tells the girl that she likes girls with big breasts).
I'm probably just pushing my own thoughts on to her character at this point tho. Thank you for your two cents!

That's what I thought, she's being pushed around by all their wishes and demands. You'd think after living 8 lives with misfortune and being an angel she would be wise enough to advise them against being overly greedy and selfish. Where did that rightness when she taught that old woman at the brothel go?? And also I feel as though the story sped up a lot after the incident, like suddenly she's training to be a spy; she's actually good at it and stronger than the men; her partner found out he's a she; they infiltrated; she met the knight. The pacing felt really rushed

I don't have a problem with her having an attachment. That's, well, nice I guess? To care about others?
What I absolutely can't condone is her stupidity and the way she goes about it, though. There's a difference between getting attached and letting herself strung along. She acts like she cares but...does she really? If she really did care, would she let the children risk their lives for some uncertain future with a plan that could go wrong in so many ways? I can only assume she liked them, but not enough to really care about them, her future is already set after all. That would be the only logical explanation, but then she acts all surprised and...it just gets to me, I guess. Care r don't care, but don't go around acting all innocent cause one way ore another, even if it was by ignorance, you were the one that got them killed.

I came here expecting your usual plot of "oh hey, I got banished purposely here are my plans" sort of villainess reincarnation story... and then I got this interesting plot heavy piece
I love this story so far. I love our mc's struggles, the interesting reflections on the idea of finding your own happiness. Everything about this has such a nice emotional depth to it that you usually don't find in this genre. I want to know where the plot is moving next
So so wholesome, this whole thing. The author really does live up to their name. Honestly that ending is so sweet I feel like I'll get diabetes
