@Vive I think her previous life weight so much more to her, that's why. It's a traumatic life yes but still a life she live through and cannot be undone even if her memories are stored somewhere to never be remembered again.
And just because her life is good in the next life and she is loved and treasured, that doesn't mean she would brush her previous life off like it's nothing, that life is full of betrayal so now that Sanya and the Empress remembered her prev. Life it's like another betrayal through deception, it's understandably that Sanya would think the Empress would be atoning for her faults but as you can see Sanya was more reacting to the "the past is just a past." Because her past life does undeniably weight more in her heart.

I'm trying my best to wrap my head around this but- isn't she over reacting? Yes they were mean to h...
Well, if I'm stuck in a novel I would crash out too. I mean, Hestia only anchored herself to hold on to live on by taking revenge for his beloved one but suddenly that beloved one announced he's done with the only fight She's been going through and stayed neutral and Hestia really take Kael's opinion to heart because she really love him and would follow through what he decided, but then Kael did it like cutting off the heavy anchor from her leaving it unresolved, so it's like Hestia was just now in a limbo.... So yeah... that's really understandable existential crisis there. I don't know if I explained it right... Whatever my thoughts are tangled.
