What's in that hocus pocus?!

I think it's from her mom(lilith)

So if she reads it she return to her normal self and wear white outfit.. As the maid said it makes her return to her true self as in the original character behavior but she clearly hates her mother.. I wonder if it's from her mother..

What???

Apparently the mother is the one who is reincarnated into this world not Lilly. She has used a lot of cruel methods to make Lilly the main protagonist which is why she hates her mother. Her mother has literally been beating the lileth of the story into her from a young age. She's rebelling against her mother by acting like a whore
