The only problem with any past seninna matters comes from the original. Our new Sena won’t remember or know anything that happened unless she’s told about it. She can’t apologize for something she herself never knew or did. I do agree with the fact that they did neglect her and brush aside her trauma. Although they seemed surprised by the extent of the abuse too. The society though is definitely the type to ignore and brush past any trauma and depression. They considered that stuff to be a real illness and treated it as such. Along the lines of “that person is crazy we can’t do much for it so just leave them and do your best to make their life easier, even if that’s ignoring them”
I may be the weird one but up till a few chapters ago the family was brushing off her depression, anxiety and suicidal tendencies and actions. I found that really weird to be honest, in that society it seems like it's looked down upon but it's obvious something was wrong with the people in the house for her to be acting like that.
Lots of stuff may have happened in the past with this charcter but it's honestly weird, it's like the family was turning a blind eye to it and only after the last attempt when she made an effort as a different soul did they notice and start to use her.
The family is full of hypocrites but the girl wasn't even better, she probably hasn't even apologized for what she said to him as a kid, if she remembers she will probably feel horrible because after that, I would neglect her as well. That's emotional truama right there and probably had an effect of his later behavior aswell, hence why he probably does his hair that way to cover up the scar or it's already healed with magic and his ruthless behavior. The exact same thing that slob said to her is like the mirror of what she said to him AS A. KID. The difference is she's already twenty and has already lived one life and is now leading a second. But the boy only has 1 and he's probably been thinking about it for years probably even had nightmares
