Exactly, I was so confused because they keep changing details of novel.
MC died young (at that moment they met axion, mc thought because she didnt know the detail of when she died) -> MC got kidnapped but daddy doesnt know (so she died in prison??) -> she died as an adult by ml's hands right after they've beaten the emperor and daddy got frozen up -> no, actually tower master tried to shield her first with a very lengthy battle with ml but yeah daddy was still frozen up (which doesnt make sense to stand still and doing nothing to save his daughter that long)
Ok so this is how I understand it.
“Died young” aka she doesn’t have a souls and her body is just being forcibly moved through mind control, so you can’t talk to her and she doesn’t move if the primera doesn’t give her an order, that’s how she could also be “the villain at the end of the story” bc it was also said she double died once the primera (her controller) was gone like there was no saving her.
“Suddenly knowing she was a primera even though she fully believes she is an npc” she knows its a story, its just that she THOUGHT she was an npc, but once she realized who her dad was, she then realized who she was, and y’know how they give explanations into the villain’s power before the hero defeats them maybe thats how she knows og lilith is a primera.

its not like its a big deal but the author lowkey cant write women. like all the women in the fl life are just minor characters and and insignificant side characters. the aunt’s role in this manhwa is just the twin mother, and the fl mother? shes just unlikeable.
the plot is also inconsistent. in the beginning, she found out her dad is the mc and shes the daughter that died young but then she revealed she’s gonna be the hidden villain at the end of the story. not to mention how she suddenly knows shes the primera and that’s the reason for her growth stunned when in the first place she fully believes shes just an npc in the story. i feel like the author can expand a little bit of the story development instead of just relying on “og novel” trope. sorry for my language
