Spoiler
Tbh this spoiler already being told before by someone else so I just tell what I remember.. I might remember wrong so I apologise first if I said something false..
God have three favorites child but all three child's committed some sins and were curse and cursed to repeat their sins over and over again..
first child will kill his own lover/wife, second child will kill her child and the third child will kill his parents?( I'm a lil bit confused with the third child)
Second child is aisha and she killed her son (which is Abel) but the reason why she killed abel was because he was sick and to lessen his pain aisha killed him and after she regain her memories she'll have both light and dark magic..dark magic because she's cursed
The first child is the pope, he kill his wife (which is aisha) because he was mad that she killed killed their child.. this is why the pope trying to surpass her mana because he doesn't want aisha to remember their first life because if she does the curse will repeat again he's trying to break the curse..
The third child some said it is the author of the novel aisha read but idk if this is true or not so third child identity is still a mystery to me.. the third child tried to kill the god because he was mad that the god cursed the other two siblings and tried break the curse but failed.. ( I think the third child is the god most favorite child between the three siblings)
Once aisha remember her past life she told hades to kill her before she kill Abel but hades rejected the idea of killing aisha so aisha threatened hades to use her dark magic to manipulate hades into killing her..
Before this there was a woman who told hades to adopt abel that woman was aisha and she warned hades to kill any woman that tried to get close to abel and told him that she remembers her past life..
This is all the spoiler that I have I haven't looked for any new spoiler(〜 ̄△ ̄)〜
Ohh i think I read something about aisha is deborah or something but I'm not very sure about this so I might be wrong( ̄∇ ̄")

I haven't read the raws yet but I got this idea...
What if the reason they made her take the pills is because she has so much mana, more than any of her ancestors. I'm not sure but I think I read somewhere here how light users mana is like a trade off. If one light user has lesser mana, the other light user has more? What if the church has been trying to suppress her mana so that Deborah, the fl of the original novel, can have more mana? They'd prefer Deborah over her since they have a hold on OG!FL.
I have no idea if this makes sense as it sounds more like a crazy conspiracy theory than a legitimate theory, and the fact that I may be interchanging facts from other manhwas I have read, but just a thought ╮( ̄▽ ̄)╭
