I feel like Ayesha is the reincarnation of the yknow powerful thingy she died and reincarnated as a korean girl and then died a againand reincarnated as another body of her original world thats why she started getting memories that she dated mikhael dude AND Mikhael knows that Ayesha is the reincarnation because he loves her that much and Mikhael made a copy of that powerful girl that he once dated as the main protagonist AND the author is Adel before he died cause he got out of the brainwash Mikhael did to him????
MAJOR SPOILER
so basically abella, michael(past self) and the author aka procreator is the three god's beloved children.
but the three of them have dark attributes and cursed because they comitted a sins. their curse is to reincarnate again, remember their past life and commit their own sins again.
Abella comitted sins of killing her own child. she killed her child bcs she couldn't see her child suffering his illness anymore.
Michael (past self) comitted the sins by killing his lover. Though we didn't know why he killed his lover. The lover identity is abella bcs of that
when they both reincarnate michael will again fall in love with her and kill her (the curse).
The author aka procreator so he is currently living in the earth as lee shin. procreator is the most beloved child by god seeing abella and michael suffering from their curse he turned his back on the god. The god then curse him to be the one who kill his parents. (id rlly know much about the detail). Procreator create this novel universe in hoping that ayesha (abella reincarnation) and michael will found the way to break the curse.
Also about abel it seems like the one who told hades to adopt abel is janice (if im not mistaken she is one of abella reincarnation) and told him to take care of abel and protect him and kill anybody who will tried to hurt him.
The reason why ayesha died early in the novel its bcs of the pills that she is taking. The pills were provided by the church under michael order. The pills slowly killing her and supressed her own powers to prevent her remembering her past life as abella. Michael want to kill ayesha before he could fall in love with her. Soon ayesha will stop taking her pills and remebers the past.
After remember her past as abella and the curse. She told hades to kill her before she killed abel . Of course hades refused to kill the woman that he loved. it said that hades power is like close to god. Ayesha also said she could brainwash hades to kill her (ayesha has divine power and dark power). but Hades told her that he will find a way to break the curse.
Thats it hope you understand. I'll try to summarize as well as i can.
Im sorry wtf is hapening technically
